2 GIO LAND SERVICE CONTINENTAL COMPONENT

CLC2012 inventory is carried out within the frames of GIO land Continental Component

For sake of completeness a brief overview of the GIO land Continental Component is

given below

Figure 1 Production scheme for pan-European continental component of GIO land services

(extracted from PIP)

The Pan-European continental component of the GIO land service includes the following

steps (Fig 1)

1 Post-processing of space data and the automatic extraction of

intermediate products including the production of Pan-European mosaic of

ortho-rectified high-resolution (HR) images and intermediate products such as

bio-geophysical variables based on HR space data

2 Production of five high-resolution layers with land cover characteristics (ie

attributes of comparable quantitative measures across Europe) related to the

mapping and change mapping of artificial surfaces forest areas agricultural

areas wetlands and water bodies at pixel level and validated at 1 ha grid cell The

production of the five high resolution layers (HRLs) shall include for full

geographical coverage

a Artificial surfaces Mapping of degree of imperviousness

b Forest areas Mapping of tree cover density and forest type

c Agricultural areas Mapping of permanent grassland The analysis will use

the three reference years 2006 2009 2012 to detect the permanent presence


of grassland The discrimination of permanent grassland from other

agricultural land areas such as arable land bare soil etc should take into

account seasonal variations based on AWiFS data (reference year 2012)

d Wetlands Mapping of presence of surface water during the reference year

(2012) Seasonal changes using AWiFS data will be used to map areas covered

temporarily by water

e Water bodies Mapping of permanent water bodies The analysis will use the

three reference years 2006 2009 2012 to detect the permanent presence of

surface water Seasonal AWiFS data will be used to separate temporary water

from permanent water bodies

3 New CORINE Land Cover inventory including

a CORINE Land Cover Change (2006-2012) mapping of all land cover changes

between 2006 and 2012 with a spatial resolution of 5 ha for the standard 44

CORINE Land Cover classes

b Production of CORINE land cover map 2012 generalized to 25 ha

minimum mapping unit Including derived gridded data in 100m and 250m

resolution

4 Validation and quality control of products

5 Collection of in-situ data required for the pan-European continental activities

ie non-space data including ancillary and reference data at European and

national level Collecting national level in-situ data is the responsibility of the

countries

Institutional actors involved in the coordination

EC General Directorate for Enterprise and Industry (DG-ENTR) as leading

governance body

authorities nominated by the Eionet National Focal Points (NFPs)

Following this overview in the rest of the document only questions related to CORINE

Land Cover are discussed


3 IMAGE2012 BASICS

Access to remote sensing data under GIO is handled by ESA For the period 2011-2013 a

new concept of Data Warehouse has been developed The new approach is based on the

procurement of a set of common and pre-defined core datasets made broadly available

to public organisations at European and national level A data access portfolio3 (V25 at

the time of writing) describes the datasets available

A new agreement for data access (Data Warehouse) to provide access satellite data for

GIO land 2011 ndash 2013 has been concluded The agreement intends to provide multiple

right of use of the ortho-corrected satellite images as long as traceability of use is

ensured National Teams will be granted access to these data for internal use as soon as

the Data Warehouse Licence will have been signed There will be no IMAGE2012 delivery

on DVD like eg in CLC2006 but images will have to be downloaded from the Data

Warehouse

31 HIGH-RESOLUTION SATELLITE IMAGES (IMAGE2012)

Two coverages of pan-European multi-temporal ortho-rectified satellite imagery covering

all 39 participating countries and 12 nautical miles sea buffer will be delivered by ESA

(based on the Data Access Agreement) for the period of 2011-20124 with all spectral

bands and cloud masking This set of imagery is called IMAGE2012 (compare with

IMAGE2000 IMAGE2006 IMAGE2009) The raw images will be projected into national

projection systems These images will be the main satellite data input for producing the

core land cover data (CLC2012 databases and high-resolution layers) Two dates of

acquisition (acquisition windows specified by countries) with cloud-free data (maximum 5

cloud coverage) are envisaged to be collected for each area Images will be made

available to contractors and participating countries on a NUTS2 level equivalent reference

layer

In year 2011 high-resolution satellite images covering 13 of Europe have been acquired

In year 2012 images will be acquired for 23 of Europe The ortho-corrected imagery

should be available for the national teams in January following the image acquisition year

the latest (ie January 2013 and January 2014) In 2014 only gap-filling acquisition is

planned with very low percentage of the total coverage

According to the GSC DAP DWH document the following type of imagery is available

(Table 4)

Coverage one (1st priority by countries) is planned to be completed normally by

the Indian IRS Resourcesat-1 and Resourcesat-2 satellites Data are delivered in

20 m pixels in national projection and in 25m pixels in European projection This

dataset is included in CORE_01 of DWH

Coverage two (2nd priority by countries) is planned to be completed normally by

the German RapidEye satellite constellation RapidEye includes spectral bands in

visible and near infrared bands but not in SWIR band Data are delivered in 20 m

pixels in national projection and in 25 m pixels in European projection A 5 m pixel

size version in UTM projection also exist This dataset is included also in CORE_01

of DWH

Access to former pan-European coverage (eg IMAGE2006 IMAGE2009) This

Additionally a medium-resolution monthly (March ndash August) time-composite IRS

AWiFS data are available especially to support the derivation of some of the high-

resolution layers This dataset is included in CORE_08 of DWH

311 Quick guide to access satellite imagery

Participating countries gain access to satellite imagery though a multiple-step registration

system and a number of interfaces maintained by ESA Procedure is rather complicated

with interrelated steps information on use scattered over different websites therefore a

road map guiding through the process is given below (Description includes a large

number of abbreviations needed for identification of elements of the system Collection of

their explanation is found in Chapter 83)

3111 Registering at ESA as GMES user and signing the licence agreement

In order to get access to satellite imagery first a user account for GSCDA has to be

requested from ESA As first step GIO implementing organization has to register as

GMES user at ESA and sign licence agreement between you and ESA Steps of this

process are as follows

1 For registration at ESA in order to become an eligible GMES user e-mail has to be

sent to gmesdataesaint

In reply ESA will send two attachments

SP_Member_List_Templatexls excel file with two sheets both of which

should be filled in

ESA (called CDS-SCI)

3112 Selecting image data using EOLi-sa and downloading through ftp

There are two separate interfaces for selecting required satellite data and for

downloading it The process has three steps using the two interfaces

1 Browsing and selecting requested EO (satellite data) in EOLi-sa catalogue program in

GMES User mode After selecting required data a kmz file containing information on the

images selected should be created (For detailed description of the process see Box 1

below)

In order to be able to log in to EOLI-sa a GSCDA Service Project Personal Account with

the UM-SSO ID (User Management Single Sign On) should be created This account name

and password is given to operators (not the organization) named in Point of contact

Data Access sheet referred to at 3111 at bullet point 1 Process of acquiring an UM-

SSO ID is explained in the link below

5 The GSCDA data and services are accessible in the form of Datasets (there are two types of Datasets CORE

and ADD out of which the first one is relevant to GIO) Access to the Datasets will be granted to the GMES Service Projects (in practice GIO implementing national organization) CORE Datasets are the fixed part of the DWH offer they are pre-defined large datasets covering among others the needs of the operational services to be initiated under GIO

4 PRODUCTION OF CLC-CHANGE2006-2012

41 CHANGE MAPPING

This chapter is partly a repetition of the TGrsquos relevant chapter with some elements more

emphasized and some new elements added

Similarly to the last CLC inventory CLC-Change2006-2012 is the primary and most important

product of the CLC2012 project CLC-Change2006-2012 is an individual product (ie not

derived by intersecting CLC2006 and CLC2012) having a smaller MMU (5 ha) than CLC2006 (25 ha)

The aim is to produce European coverage of real land cover changes that

ndash are larger than 5 ha

ndash wider than 100 m

ndash occurred between 2006 and 2012

ndash are detectable on satellite images

regardless of their position (ie connected to existing CLC2000 polygon or being ldquoislandrdquo-

like)

The production will be carried out by national teams (the Eionet National Reference

Centres for spatial analysis and land cover - NRCs) which combine best expertise with

local knowledge and where ancillary data are available for mapping land cover changes

The overall thematic accuracy of the change database shall be gt85 (similarly to CLC2006)

Mapping of CLC changes should be carried out by applying the lsquochange mapping firstrsquo

approach meaning that changes are interpreted directly based on comparison of

reference images Visual comparison of IMAGE2006 with IMAGE2012 satellite imagery

(with CLC2006 vector data overlaid for spatial reference) is followed by direct delineation

of change polygons Practically if change occurred to a CLC2006 polygon it should be

transferred to the database of CLC changes where the changed part will be delineated

and kept as polygon (Fig 2) At the end of process CLC-Change2006-2012 polygons will be

combined with CLC2006 polygons to obtain CLC2012 database Necessary thematic

geometric correction of CLC2006 data must precede the delineation of change polygons

in order to avoid error propagation from CLC2006 to CLC2012

Therefore change mapping consists of two steps namely CLC2006 correction and

interpretation of changes that occurred between 2006 and 2012 The two processes can

be carried out consecutively or in parallel but on level of individual polygons correction must always precede change delineation (see Ch 412)

The basis of identification of changes is the interpretation of visually detectable land

cover differences on images from 2006 and 2012 Ancillary data such as topographic

maps orthophotos HR layers (derived from satellite imagery) Google Earth imagery are highly recommended to use

Delineation of changes must be based on CLC2006 polygons in order to avoid creation of

sliver polygons and false changes when producing CLC2012 database This means that

during interpretation of changes CLC2006 polygons must be visualised for and used by

the interpreter so that outlines of CLC-Change2006-2012 polygons exactly fit CLC2006 boundaries See Fig 2


Interpreter must give two CLC codes to each change polygon code2006 and code2012 both

included as separate attributes These codes must represent the land cover status of the

given polygon in the two dates respectively Change code pair thus shows the process

that occurred in reality and may be different from the codes occurring in the final CLC databases (due to generalisation applied in producing CLC2006 and CLC2012)

The CLC2006 polygon

including the change is

taken over into the

CLC-Change2006-2012 database

The change area is outlined

by the photointerpreter

The non-changed area is

deleted and the change is coded (211-121)

Figure 2 A method of using

CLC2006 polygons as basis for change delineation is taking over the changed CLC2006 polygons

into the CLC-Change2006-2012 database then outlining the

changed part then deleting the unchanged part


411 Input vector data

There are two input vector layers to be used in implementation of change mapping

The first and most important of these is the CLC2006 database Similarly to CLC2000 a

border-matched version of CLC2006 has been produced by EEA in order to eliminate

inconsistencies along state boundaries As most of the borders were already matched

during the CLC2000 project only a limited level of border matching took place this time

mostly affecting borders of countries newly entering the project in CLC2006

For consistency reasons all countries are expected to use that national version of

CLC2006 which has been clipped from the recent integrated European version These

(vector format national projection) can be downloaded from Eionet Forum (see link below)

Use of CLC-Change2000-2006 in deriving CLC-Change2006-2012

In former CLC inventories geometric and thematic consistency of change databases

following each other was not examined and not considered After completion of the

CLC2006 inventory a study revealed that inconsistencies between the two available CLC-

Change layers exist (see Box 2) Inconsistencies proved to be numerous but not

significant regarding area covered (less than 1 of changed area)

Box 2

Contradictions between CLC-Change1990-2000 and CLC-Change2000-2006

[G Maucha Gy Buumlttner and R Pataki Development of methodology to eliminate

contradictions between CLC-Change1990-2000 and CLC-Change2000-2006 ETC-SIA Report

06302011] were analysed by examining cases where code_2000 of the old (CLC-

Change1990-2000) and the new (CLC-Change2000-2006) change databases did not match on

the same location It was found that

Disagreements between old and new CLC-Change layers are result of combined

effect of obvious positional inaccuracies in delineation slight uncertainties in

application of CLC nomenclature and mistakes in interpretation

Largest number of mismatches was found between forestry changes

Two typical occasions when disagreements were often found

(1) CLC change continued in time on the same area eg 211-133 between

1990 and 2000 while 133-112 between 2000 and 2006 (if mapped

properly)

(2) CLC change continued in the neighbourhood of an existing change polygon

eg 324-311 between 1990 and 2000 and the same type of change in the

neighbour area between 2000 and 2006

Small average polygon size in a disagreement type most likely meant slight

differences in delineation of neighbouring changes (most of disagreement types)

Large average polygon size in disagreement type most likely meant

interpretation mistake either in CLC2000 or in CLC2006 Two such common

interpretation problems are distinguishing between 324 and 321 and between

324 and 323


Aiming to avoid introducing more such inconsistencies national teams are asked to use

the CLC-Change2000-2006 database of the previous CLC inventory as an ancillary support

layer to keep consistency of the ldquooldrdquo and ldquonewrdquo change layers In practical terms

harmonization requirement means that in locations where CLC changes exist in both

layers the same code_2006 is expected to be given in both change databases

However there is no intention to revise CLC-Change2000-2006 data consequently mistakes

found in it are not requested to be corrected On the other hand the CLC-Change2006-2012

should reflect reality visible on images as much as possible Therefore there is priority of

producing a correct CLC-Change2006-2012 over harmonizing code_2006 with CLC-

Change2000-2006 (Ie if a wrong code_2006 is discovered in CLC-Change2000-2006 it should

not be taken over to CLC-Change2006-2012)

In deriving CLC-Change2006-2012 CLC-Change2000-2006 data are recommended to be used in

the following ways

(1) If CLC change continues in time on the same area the change code sequence

should indicate it Eg construction process on arable land 211-133 between

2000 and 2006 133-112 between 2006 and 2012 Try to use the same

outline in the new change polygon as much as possible

(2) If CLC change continues in the neighbourhood of the existing change polygon

Eg 324-311 between 2000 and 2006 and the same type of change in the

neighbour area between 2006 and 2012 In such cases attention should be

paid to drawing the boundary between the ldquooldrdquo and ldquonewrdquo change so that

overlap is minimized

412 Particular requirements concerning CLC2012 mapping

There are particular requirements of change mapping that were indeed mentioned but

(as shown by experience gathered during the CLC2006 verification process) probably not

emphasised strongly enough in CLC2006 Technical Guidelines

4121 CLC2006 correction

Occurrence of interpretation mistakes is an inherent characteristic of visual interpretation

of remote sensing data coming not necessarily from negligence but insufficient

information During updating by examining newly available satellite images or ancillary

data usually a number of thematic mistakes are discovered in the database to be


updated In order to avoid error propagation into CLC2012 mistakes discovered in

CLC2006 are much recommended - in locations of changes absolutely necessary - to be

corrected

These are

1 Systematic mistakes known from the previous inventory but not corrected yet and

ones discovered during change mapping These are relatively easy to find by searching

for the codes that show systematic mistakes Systematic improvement of geometry can

also be included here

2 Random mistakes These are usually ad hoc discovered during change mapping or can

be systematically searched for by visually browsing CLC2006 map in scale 130000-

40000

In case national team decides not to modify previously submitted CLC2006 data the tool

of technical change (polygons of any size in the change database having similar codes for

2006 and 2012) can be used for correction (and transfer of correction to CLC2012) If

used for correction technical changes can be larger than 25 ha Eg if a 50 ha polygon is

coded as technical change (121-121) it means that 50 ha industrial area was not

mapped in CLC2006 As a result of using technical change CLC2012 will include this 50 ha industry as correction

The process of CLC2006 correction can be done either before starting change mapping or

in parallel with change mapping (depending on the software used) However interpreter

must make sure that correction of an individual CLC2006 polygon is always done BEFORE a change is mapped in the same location

4122 CLC change interpretation

1 Geometry

a) The mapping of CLC changes must be done using the geometrical basis of CLC2006

polygon layer The outline of change polygons must therefore match CLC2006 polygon

border otherwise false changes and geometric mistakes occur This means that firstly

there should not be any narrow channels (Fig 3) between or slivers around change

polygon outlines and CLC2006 polygon outlines secondly change polygon outlines

should nor criss-cross over CLC2006 outlines (Fig 4) These mistakes can be most easily

avoided by applying the recommended method of change mapping taking over polygons

from CLC2006 to change database then drawing changes then discarding not changed

parts

b) Topological consistency must be kept Change polygons should not overlap each other


IMAGE2000 + CLC2000 (yellow) IMAGE2006 + CLC-Change2000-2006 (magenta)

Figure 3 Mistake Narrow channel between change outlines (magenta) and CLC2000 outlines (yellow)


Figure 4 Mistake Change outlines (magenta) not matching CLC2000 outlines (yellow)

2 Coding

Interpreter should give two codes to each change polygon according to what is visible on

the relevant imagery one representing land cover in 2006 and the other in 2012 Change

codes should always represent the change process that happened in reality Therefore

codes can be different from respective codes in CLC2006 and CLC2012 databases Eg if

a 15 ha urban green area is being built up change polygon should be coded 141-133

while due to generalization the area is coded as 112 both in CLC2006 and in CLC2012 databases (Fig 5)


Figure 5 Interpreting a real change the loss of urban green (141) lt 25 ha by becoming a construction site (133) must be coded 141-133 in the CLC-Change database although the patch is generalised into discontinuous urban fabric (112) in both CLC2006 and CLC2012

The two codes of change polygons should be described by two different attribute fields in

the data table (called eg code06 and code12)

When giving the codes interpreter always must be able to answer the question what is

the process described by the code I gave Is this process the same what I see on the

image pair Is this really a CLC change This way interpreter can avoid mapping seasonal

differences as change or giving attributes that are meaningless on the field

3 Image dates

In order to avoid mapping seasonal differences as change interpreter should always be

aware of image dates (year and month at least) The best way to achieve this is to

include image date in the image name so that it is visualised all the time It is the same

reason that makes image mosaics of limited use for CLC change mapping in a mosaic

image dates are hard or impossible to check and radiometry (colours) are often strongly

distorted Knowing image dates is especially important in the following cases

Mapping vegetation of mountainous areas vegetation reaches its full

development foliage cover late in the year only around June so earlier images

might mislead interpreter

Mapping hot and dry (Mediterranean and strongly continental) areas vegetation

is usually dried out by early summer which is the ldquonormalrdquo date of images for

land cover mapping Thus vegetation (arable crops grassland) is not detectable

on images or it is almost impossible to distinguish arable fields from patches of

natural grassland or even sparsely vegetated areas Therefore ancillary images

from AprilMay are highly recommended to use in such areas (eg Iberian

Peninsula Anatolia) The same is true for distinguishing natural grassland areas

from sparsely vegetated areas or bare rocks

Mapping changes of lakes especially water reservoirs being unaware of image

dates might lead to mapping seasonal water level fluctuations (lakes shrinking

due to summer heat and water take-up for irrigation) as permanent changes

which is a mistake Same is true for Alpine rivers where highest water level

occurs in springearly summer due to snow melt

Mapping glaciers and permanent snow images of not exactly the same date

(which should be the date of smallest snow extent late August or early

September) are not comparable thus using them leads to mapping false

changes

4 Nomenclature

There are a few conclusions coming from lessons learnt during verification process that

are not or inadequately described in the latest version of the CORINE land Cover

nomenclature so are reasonable to be described here Issues are listed in the order of the relevant CLC code

Industrial and commercial sites (121)

Geothermal fields together with pipelines and the surface between them should

be coded as industry (121) even though real land cover between the pipes is

usually natural

Construction sites (133)

The deposited material along road constructions should be part of the road

construction polygon (133) Interpreter should be aware that these areas are

normally turned back to arable land grassland or are forested after construction

is finished which is a change (133-22x or 133-324) not be missed when

interpreting changes

Construction of ldquoartificial naturerdquo ie natural habitat reconstruction works for

conservation purposes are also part of class 133 As this kind of construction is

not to be considered ldquoharmfulrdquo for environment in the analyses there might be a

need to differentiate from ldquotraditionalrdquo constructions A way of doing this is giving

an additional attribute or assigning it to a level-4 class (for national use only)

indicating that given construction polygon is not going to turn to built-up in the

future Construction of golf courses might also fall into this category

Generally constructions do not last longer than 6 years so these polygons are

likely to have change Checking all 133 polygons in CLC2006 systematically helps

interpreter to avoid omitting these changes

Sport and recreation area (142)

Artificial snow According to the nomenclature ski pistes are not mapped as part

of ski resorts (142) as they can be considered natural grassland most of the

year However in recent years many ski resorts have been equipped with

facilities producing artificial snow (snow canons) Essential part of this

infrastructure is a pond providing water Sometimes the slopes where artificial

snow is applied are fully changed the uneven ground is levelled rocks are

removed etc Chemicals are also mixed into the artificial snow to assure higher

melting point Due to use of artificial snow the length of the season is about

twice as long as before lasting from November to April therefore human impact

on the environment is increased Based on the above it is considered acceptable

to map the creation of such areas as 3xx-142 change (together with pistes) if the

infrastructure (water ponds) is visible

Holiday cottages In Scandinavian countries holiday cottages often far from any

settlement are being built The spatial structure is very loosely built-up houses

are several hundred metres away from each other in most of the cases lacking

any infrastructure (such as roads) These ldquoholiday settlementrdquo do however have

an impact on the environment especially in otherwise untouched areas so it is

important to map them Therefore it is acceptable to interpret these cottages

together with natural vegetation among them as 142

Burnt areas (334)

Burnt forests and shrubland mapped as 334 usually should change in six years

Ie it is expected that 334 polygons in CLC2006 will change in CLC2012 In case

of forests the usual process is the regeneration (334-324 or 334-31x) depending


on the level of damage and the speed of regeneration (more details in Manual of

CLC Changes)

Inland salt lakes and wetlands (411)

Salt marshes along the shores of high salt content lakes far from sea (typical in

Turkey) should not be coded as salt marshes (421) in CLC but as wetland (411)

Salines (422)

Areas of salt production by evaporation should be coded as 422 regardless of

their location (seaside or inland typical in Turkey) Abandoned salines on the

coast should be coded as 421

42 CLC2012 SUPPORT PACKAGE

As part of contribution to the implementation of GIO land ETC-SIA has been

commissioned by EEA to develop a software tool for CLC change mapping by

photointerpretation Development of the lsquoCLC2012 Support Packagersquo is based on the

experience gained during development of former CLC change mapping support packages

user feedback requirements and recent technical considerations

The CLC Support Package will be available for all participating national teams free of

charge from 1st December 2012 Detailed help and printable users guide (in English) as well as user support are inherent parts of the package

CLC2012 Support Package is a significantly modified and improved version of the

CLC2000 and CLC2006 Support Packages (see description in Box 3) successfully used

by a number of national teams and the CLC Technical Teams during the previous two CLC

inventories Its main novelties compared to former packages are 1 on-the-fly

coordinate reference system transformation capability (no need to have all data in the

same projection) 2 ability of using data from web map services (WMS) 3 CLC2012

Support Package is a set of standalone applications developed with Embarcadero Delphi

XE2 and TatukGIS Developer Kernel Thus user does not need to purchase install and

tune any other software to carry out CLC2012 change mapping

CLC2012 Support Package is a specialized task oriented software tool which significantly

facilitates updating change detection and mapping quality control and correction of CORINE land cover databases by means of computer-assisted visual photointerpretation

CLC2012 Support Package consists of three modules

1 InterChange for interpreting land cover changes Program provides a tool for the

revision of CLC2006 land cover database and supports the interpretation of land cover

changes in order to create the CLC-Change2006ndash2012 database The program provides a

convenient and easy-to-use interface for editing polygons in CLC2006 and CLC-Change

databases for viewing and modification of polygon data for finding and correction of

errors generated during interpretation and editing

Major functionalities include

- Polygon editing functions tools for error correction in CLC2006 creation

deleting of polygon in CLC-Change polygon cut split unification

- Interpretation support tools synchronized double-window environment for

displaying CLC2006 (on top of IMAGE2006) and change (on top of IMAGE2012)

data display of data for selected polygon simple polygon data editing CLC code

can be selected from a list comment display options easily adjustable several


polygon search options according to eg CLC code change type comment error supervisors remark progress status area change probability

- Error prevention functions invalid CLC codes not allowed to use warning if

basic interpretation rules (eg MMU) violated non-adjacent polygons cannot be

unified error-checking tool helps to find and correct topological (eg multipart

polygon overlaps) or other (eg zero code MMU error) mistakes

- Information support functions LUCAS data display code code change

colouring error colouring flexible code label display options detailed definition of

CLC classes available with a single click ndash description in national language can be

easily added sophisticated area measurement tools detailed help and printable users guide (all in English)

(left IMAGE2006 in background) and change mapping on IMAGE2012 (right IMAGE2012 in background)

2 InterCheck for checking databases Program serves the checking of revised CLC2006

and CLC-Change data InterCheck program has been prepared primarily for supporting

the CLC2012 Technical Team although national central teams might apply it as a tool for

checking of the completed CLC2012 and CLC-Change databases InterCheck can be used

for checking CLC2006CLC2012 and CLC-Change databases in many file formats not only those that has been prepared with InterChange

Major functionalities supporting control procedure polygon editing not

allowed verification units can be assigned sophisticated search tool according to

several characteristics such as CLC code change type remark area change

probability or technical change remarks can be added to polygons and any point in both databases

3 LUCAS Photo Viewer Program displays the main data and field photos (if any) of

the LUCAS (2006 2012) point selected in InterChange or InterCheck program

Further information and news regarding the CLC2012 Support Package are available at

the dedicated website httpclc2012taracsakhu


Box 3

CLC2000 Support Package was developed in order to help the implementation of the

European CLC2000 project CLC2000 software was a macro package written in Avenue

ArcViews own macro language The software was a supplement to ArcView 3233 GIS

As the CLC2000 macro package was made available for free for countries participating

CLC2000 project (on the condition that it is used solely in the implementation of the

CLC2000 project) users had to possess purchase only ArcView ldquomother softwarerdquo Use

of the Support Package significantly facilitated updating change detection quality

control and correction of land cover databases by means of computer-assisted visual

photo-interpretation The CLC2000 software was used by 15 European national

teams out of 30 participating countries for interpreting changes in CLC2000 project

CLC2006 Support Package was a significantly modified and improved version of

CLC2000 Support Package The package consisted of four main parts InterPrepare for

the preparation of source files and work directories for change detection InterChange

program provided a tool for the revision of CLC2000 land cover database and supported

the interpretation of land cover changes InterCheck program served the checking of

revised CLC2000 and CLC-Change map sheets LUCAS photo viewer displayed the

main land cover and land use data of selected LUCAS point together with field

photographs CLC2006 software was a commercial product customers therefore could

use software licenses without any time or project limitations In the European CLC2006

project 17 European national teams used this software (see figure 7)

Figure 7 copy 2012 Taracsaacutek Gaacutebor

CLC2006 verification by Technical Team was done in all 38 participating countries with

help of the InterCheck Some national teams also used it as a tool for final checking of the completed CLC2006 and CLC-Change databases


ALTERNATIVE SOLUTIONS

During the implementation of the CLC2006 project some countries (especially in

Scandinavia) applied procedures different from visual photo-interpretation for deriving

CORINE Land Cover data These solutions aimed to reduce human work-load and

combined national GIS datasets satellite image processing technology on-screen

digitization (visual photo-interpretation) and GIS-based generalisation Most of these

methods aimed to produce CLC ldquostatus layersldquo (ie CLC2006) but they were also

successful in facilitating partly solving the change mapping job

These GISIP based alternative change mapping solutions are encouraged if results are

compatible (in terms of technical features and accuracy) with the traditional method In

case of change mapping major issues of non-compliance are as follows (as experienced

during CLC2006 verification missions)

- Changes mapped are not ldquorealrdquo changes ie they do not represent a change that occurred in reality

- Changes are topologically (eg overlap) or geometrically incorrect (eg narrow or

sliver polygons)

- Change outlines do not match CLC2006 boundaries

These can be avoided by

- First of all not taking uncritically the changes derived from ancillary databases

but considering them as potential change areas which are to be visually checked

and approved by interpreters or used as background information for interpreters

in manual delineation of changes This is especially true for changes of built-up

areas heterogeneous agricultural classes and non-forested natural classes

Forestry changes are easier to be automatically detected they however also require at least partial visual control (especially forest growth)

- Making sure that source databases are timely ie not outdated but especially not

fore dated (databases of buildings or spatial planning do often contain features that are planned to be raised but in reality are still not existing)

Taking CLC2006 database as a geometrical basis of change mapping is a necessary

requirement In the exceptional case when CLC2012 is produced first and CLC-Changes

are derived by backdating geometrical and thematic compliance with new status layer

(CLC2012) is necessary


5 IN-SITU ANCILLARY DATA In-situ data in GMES definition comprise all non-space-born data with a geographic

dimension Access to existing in-situ is object of the GMES Data and Information Policy

Major use of in situ data in CLC project is to complement the satellite data in process of

production and to validate results provided from space-born data

Interpreter should be aware that primary source of information is IMAGE2006 and

IMAGE2012 which are considered reference data concerning both date and thematic

content

In-situ data requirements include

Topographic maps and basic geographic reference data which will be used during

interpretation mapping and validation process

Aerial photography thematic maps (built-up vegetation forestry hydrology

snow and ice etc) and other ancillary data (eg LPIS) for

identificationinterpretation and verification of land-cover mapping

LUCAS 2012 field survey data coordinated by Eurostat including landscape

photographs from visited points covering EU27 Primary data will be available in

1st half of 2013 In addition to LUCAS2006 data LUCAS2009 data are also

available from Eurostat6

Results of HRLs produced by using the same IMAGE2012 data under GIO land

project (especially degree of imperviousness and tree cover density forest type)

can be used and encouraged to be used as supporting information

Ancillary data complementing the above and being useful in CLC change mapping are as

follows

1 Additional satellite imagery provides more multi-temporal information This is of

utmost importance in mapping agriculture in MediterraneanAnatolian region mapping

vegetation in mountains mapping glaciers avoiding transitional phenomena (eg floods)

falsely mapped as change Straightforward additional satellite imagery is IMAGE2009

which can be downloaded from DWH Core_02 dataset7

2 Google Earth imagery (or equivalent) provides (often multi-temporal) VHR data

where no ortho-photos are available Major uses are identification of fast-changing

processes (eg constructions) identification of plantations (both fruit and forest) dehesa

montado and scattered holiday cottages and their changes use of field photos

Interpreter however should always a) be aware of GE image dates b) treat GE data with

a due precaution as non-valid image dates might occur Ie if GE data contradicts

IMAGE20062012 the latter should be used as reference

6 PRODUCTION OF CLC2012 DATA In the CLC2012 project the CORINE Land Cover database is updated by the bdquochange

mapping firstrdquo approach This means that national teams interpret all changes that are

larger than 5 ha The given change codes should approximate as much as possible the

real evolution process During change mapping discovered errors (thematic as well as

geometric) of CLC2006 have to be corrected providing a CLC2006rev dataset (or a layer

of technical changes)

CLC2012 database will be produced by adding CLC2006rev and CLC-Change2006-2012 in a

GIS similarly to CLC2006 project

The two major prerequisites of producing CLC2012 out of CLC2006 and change data by

GIS is that

1 CLC-Change2006-2012 outlines are geometrically based on CLC2006 outlines

2 Both CLC2006 and CLC-Change2006-2012 are topologically correct databases (no holes

no overlaps no multi-part polygons no dissolve errors)

If any of these conditions are not fulfilled GIS operation will produce false result and

slivers therefore will give an incorrect CLC2012

Integrating CLC2006rev and CLC-Change2006-2012 in order to produce CLC2012 should rely

on the equation

CLC2012 = CLC2006rev (+) CLC-Change2006-2012

Where (+) means the following operation CLC2006rev (revised CLC2006) and CLC-

Change2006-2012 databases are intersected then CLC-Change polygonsrsquo code2006 is

replaced by code2012 and finally neighbours with similar code are unified Small (lt25

ha) polygons are generalized according to a priority table As an option polygons slightly

below the 25 ha limit (eg 24 ha) can be manually enlarged by a photo-interpreter The

ETC-SIA Technical Team provides an ArcInfo script written for the ldquointelligentrdquo data

integration like in CLC2006 project8

Eionet Forum)


7 META DATA

Similarly to CLC2006 project two levels of metadata are produced in CLC2012 project

71 WORKING UNIT-LEVEL DOCUMENTATION

The purpose of the working-unit level documentation is to document all steps of

production of the CLC-change database National teams are responsible for preparing

working unit-level documentation for their CLC-change database for internal use within

CLC projects The templates for 2006 and 2012 and an example of a filled-in form can be

found in Eionet Forum httpforumeioneteuropaeunrc_land_coverslibrarygio-

landcorine-land-cover-clctechnical-guidelinesmetadataworking-unit-level-metadata

72 COUNTRY-LEVEL METADATA

Country-level metadata mostly serve the users by informing them about the main

parameters of the product

Country-level metadata are to be produced by the national teams for CLC-Change2006-

2012 CLC2012 and if applicable for the revised CLC2006 databases

Since country level metadata for CLC products include information common to all

countries a template XML file specific for CLC has been prepared9 and can be found in

EIONET Forum at


clctechnical-guidelinesmetadatacountry-level-metadata

Country-level metadata can be edited with the INSPIRE metadata editor and saved in a

new XML file XML files should be delivered together with CLC2012 map products

Since the direct editing of an XML file is rather complicated for metadata editing we

recommend to use the INSPIRE metadata editor10 available at httpinspire-

geoportaleceuropaeueditor With the help of this tool one can open previously saved

XML files containing metadata edit them and save in a new file

Be aware that currently only INSPIRE core metadata elements can be entered and

edited with this tool (not possible to add theme specific metadata) For this reason other

XML editors can also be used

An example of a pdf file with metadata for CLC can be found in


clctechnical-guidelinesmetadatacountry-level-metadataexample It is meant to give

an example of what can be written in the country specific XML file Titles like abstract or

resource constraints should be maintained As for lineage we give an example used for

CLC Luxembourg

9 For information country-level metadata for CLC2012 products is INSPIRE compatible and applies EEArsquos requirements which follow the ldquoGuidelines for creators of metadata related to spatial

datasetsrdquo found in httptaskmaneioneteuropaeuprojectssdiwikiCataloguemetadata_guidelines

8 TRAINING AND VERIFICATION

Training and verification for CLC2012 are implemented by the CLC Technical Team under

the guidance of the EEA similarly to previous CLCs

81 TRAINING

In CLC2006 project training of a National Team was organised only on the request of the

team

As the methodology of CLC2012 is the same as that of CLC2006 training will be held

only in exceptional cases on the request of the country in their national proposal for GIO

82 VERIFICATION

In CLC2006 usually two verification missions were organised to each participating

country This was the best way to understand country-specific problems and discuss with

national experts In-situ data (especially ortho-photos and topographic maps) available

only in the countries were valuable source of data to understand problems and find

solutions

Due to the large number of participants (39) and the short implementation time of

CLC2012 (15 years = 68 weeks) it would be difficult to apply the ldquotwo visits in each

countryrdquo strategy for all participants (there would be 78 missions) Therefore a flexible

mix of ldquoremote verificationrdquo (data sent to Technical Team for remote checking) and on-

site missions will be implemented On site missions are mostly planned for countries

which are new in CLC (Albania Kosovo) or which have a reorganised CLC team

Similarly to CLC2006 in CLC2012 two verification actions per country are planned

1st verification (usually remote verification) is due when the first few working units are

interpreted (eg 10-30 of the country) The main purpose of this mission is to reveal

problems in the early phase of implementation Countries new in CLC or having less-

experienced CLC team will be visited A new element is that in countries working with

regional teams (eg Croatia Italy Spain) all regions need to send separately a sample

for first verification

2nd verification (in majority of cases remote verification) is due when around 75 of the

country area is interpreted The main purpose of the mission is to check the database

close to completion and suggest improvements if needed

To support remote verification the following materials will be requested from National

Teams to be made available via ftp

Coverage of completed databases (revised CLC2006 and CLC-Change2006-2012)

Topographic maps covering working units selected for verification

Optionally other in-situ data supporting interpretation are also much welcome by

Technical Team executing the verification The InterCheck software (known from

CLC2006) will be used in the verification Remarks will be written into the CLCCLC-

Change database (associated to a polygon or a specific location) if mistakes were found

in order to orient the correction The results of the verification will be expressed in

qualitative terms (applied already in CLC2006)

A (accepted) means only minor problems were found

CA (conditionally accepted) means there are more problems but relatively easy to

correct following corrections the working unit is accepted


R (rejected) means there are many mistakes in the database (incorrect application of

the nomenclature omitted changes false changes etc) which takes considerable work

to correct


9 DELIVERABLES11

Delivery of national CLC2012 products from National Technical Team (NT) to the EEA is

part of the CLC2012 planning in countries and follows the agreed CLC2012 projects

schedule Any foreseen alteration of the delivery schedule shall be indicated to the CLC

Technical Team in advance so these can be accommodated appropriately in the project

plan

National data can be considered as lsquoready for deliveryrsquo after the following steps are

fulfilled

1 Last verification mission of CLC Technical Team took place and Verification Mission Report has been issued

2 Recommendations specified in the Verification Reports have been integrated into the data by the NT

3 Technical quality of deliverables has been checked internally by NT and screened using

online tool (see Ch 911) to conform to all specifications as defined in the CLC2006

Technical Guidelines and summarized in the lsquoDelivery Guidelinesrsquo (see Ch10 in CLC2006


Compared to CLC2006 there is an additional delivery revised CLC200612 The following

deliveries [delivery file name] are expected from the countries (xx means the two

91 DELIVERY PROCEDURE

911 Online quality screening

When deliveries are ready to be uploaded into CDR folders dedicated for national

CLC2012 deliveries the NT performs final quality check using the CLC QC Tool - online

technical quality screening service Conformity to the CLC specifications as defined in the

technical guidelines can be checked there and results are provided visually as well as

11 Written by T Soukup (GISAT)

12 Revised CLC2000 in CLC2006 project was not an obligatory deliverable and was strongly

missing in indicator development Revised CLC2000 was collected following the completion of

CLC2006 and needed significant extra efforts This should be avoided in CLC2012


reported via dedicated reports and errors correction supporting GIS files in automatic

manner The tool supports national teams in their DIY compliance checking in order to

assure conformity of the final deliveries prior to upload to EEA CDR in a standard

transparent and more effective way This shall streamline final data acceptance and

provision of the DBTA Report - the Database Technical Acceptance Report

CLC technical quality screening service is available as web service via web address

httpclcqcgisatcz The service launch will be announced via EIONET forum in the

2Q2014 and eligible national team users will be notified with access information For

detailed information about the CLC QC Tool functionalities please consult documentation

(The CLCQC Tool Quick Guide April 2014) For any additional questions related to

CLC2012 technical quality screening service please contact tomassoukupgisatcz

912 DBTA report

When online checked deliveries are uploaded into the CDR the central technical team

proceeds with final acceptance As mentioned the DBTA report contains summary of

data and metadata conformity checks as specified in the lsquoDelivery Guidelinesrsquo (see Ch10

in CLC2006 Technical Guidelines) and is therefore used either as

A - final data acceptance confirmation - to confirm that all delivery parts have been

accepted by ETCSIA without problems listing all exceptions if present

or

B ndash a part of lsquothe request for improvementrsquo from the ETCSIA documenting inconsistencies

found and guiding the NT in data improvement In this case the DBTA report draft is

accompanied with supporting information and GIS files for such guidance and sent to

National Team Nevertheless number of these iterations shall be minimized if not

avoided at all by introducing the online technical quality screening service Nevertheless

in case of some non-conformity still found in data the NT will be notified with request to


proceed with improvement of datasets new online checking and new submission into

the EEA Central Data Repository (CDR)

913 Final delivery

The final data delivery process is very simple All deliveries shall be uploaded into the

EEA Central Data Repository (CDR) In order to deliver data you have to log in with your

EIONET account and password in the relevant folder for your country in the Reportnet

Central Data Repository (see list below) You should then carry out the following steps

bull Create the delivery envelope

bull Activate the task

bull Upload your files from your system to CDR

bull Verify that the delivery is complete

bull Release the envelope (Files which should not be available to the public can be locked)

bull Finish

All final accepted deliveries (the DBTA report is issued) shall be uploaded into the EEA

Central Data Repository (CDR) subfolder named final together with the DBTA report

National CLC2012 coordinators should liaise with National Focal Points on the delivery

process to the EEA If you need any assistance during the delivery process do not

hesitate to contact EIONET helpdesk at helpdeskeioneteuropaeu or by telephone on

+372 508 4992 from Monday through Friday 900 to 1700 CET

92 COMPARISON TO 2006 DELIVERY PROCEDURE

As seen above the delivery workflow for CLC2012 update mapping remains mostly the

same as in the case of CLC2006 one In addition the CLC2012 technical quality

screening service is introduced

to guide and support NT in consistency checking providing online screening tool

to reduce number of iteration and data exchange in delivery process

and thus to streamline the overall delivery and acceptance process

This will help to assure technical consistency of each individual national CLC database

from countries in shorter time and enable subsequent smooth and fast integration of data

into the seamless European CLC2012 products
