OGC StandardsOGC Standards

Technical documents that detail interfaces or

encodings. Software developers use these

documents to build open interfaces and encodings

into their products and services.

http://www.opengeospatial.org/standards

These standards are the main "products" of the

OGC and have been developed by members to

address specific interoperability challenges.


“We can't share maps on the Web.”

”We can't deliver data to different systems.”

"We don't have a common language to speak

about our geospatial data or our services.”

"We can't find and pull together data

from our automated sensors.”

“We have security issues relating to

geospatial data exchange.”

OGC Interoperability Team recommended to sponsors that content of

OWS-8 initiative be organized around the following threads:

• Observation Fusion

– WCS 2.0 Earth Observation Application Profile, WCPS, Compliance Test Scripts

– Detection, tracking, and bookmarking of moving objects in video, implemented using

SWE and other OGC encodings and interfaces.

• Geosynchronization (Gsync)

– Geodata Bulk Transfer: The ability to distribute individual data sets and/or collections

of data sets in a consistent manner offline and over networks.

– Geosynchronization: Web services and client components to support synchronization

and updates of geospatial data across a hierarchical Spatial Data Infrastructure (SDI).



• Cross-Community Interoperability (CCI)

– Advancement of semantic mediation approaches to query and use data based on different

heterogeneous data models, which are available via OGC WFS.

– Advancement of the use of style registries and styling services.

– Advancement of the use of KML.

– Advancement of the use of UML/OCL for Schema Automation on Domain Models.

• Aviation AIXM:

development of reusable tools, benchmarking of compression techniques for enhanced

performance, advancing styling and portrayal support, and validating the emerging metadata

and GML profiles.

– Event Notification Architecture: including Digital NOTAM Events.

– WXXM and weather information: using coverages for encoding representative weather forecast

and radar datasets, supporting on-demand Coordinate Reference System (CRS)

specifications/transformations, exploring alternative distributed architectures for managing Units of

Measure (UoM), demonstrating the applications of probabilistic Terminal Aerodrome Forecasts

(TAF) decision making applications, and reviewing/validating the WXXM schemas.

Observation Fusion: Observation Fusion: CoveragesCoverages

• WCS 2.0 Earth Observation Application Profile (EO-AP) Definition and

Implementation. Build on WCS 1.0 EO-AP developed in ESA’s HMA project.

• WCS 2.0 EO-AP to include data models for:

– 2-D Coverage with latitude and longitude axes, which can represent, for example, a hyperspectral

satellite scene.

– the subset of a 2-D satellite scene (either radar or multispectral)

– a time series of co-registered 2-D satellite scenes

– Stitched Mosaic as a 2-D horizontal coverage which can refer to several co-referenced non-

overlapping Datasets;

– Dataset Series as a collection of coverages; A Dataset Series can refer to any number of co-

referenced Datasets and Stitched Mosaics.

• and supporting these data products:

– MODIS (specific products to be identified.)

– ENVISAT MERIS L3 demonstration products (http://earth.eo.esa.int/level3/)

– ENVISAT ASAR Wide Swath

– Limb-scanning instruments (e.g. Microwave Limb Sounder) typically produce vertical profiles,

– Narrow-swath instruments (e.g., CALIPSO) produce vertical cross-sections.

• and these encodings:

– GeoTIFF, netCDF / CF-netCDF, JPEG2000, HDF-EOS

Observation Fusion: Observation Fusion: CoveragesCoverages -- 22

• Develop WCS 2.0 Extensions for band subsetting, scaling & interpolation,

EPSG CRS

• Deploy a WCPS that provides multi-coverage fusion capabilities with different,

heterogeneous raster types, for example 1-D sensor time series, 2-D

hyperspectral remote sensing data and bathymetry/elevation data, 3-D EO time

series, 4-D climate data.

• Design WCS 2.0 EO-AP to scale to large number of coverages as is typical in

the data archives of ESA and NASA.

• Develop sufficiently complex WCPS queries, taken from real-life examples, to

make them convincing to domain experts.

• WCS 2.0 EO-AP Compliance Testing. Develop Compliance Test suite for the

WCS 2.0 AP including completing the ATS and developing the ETS and

Reference Implementation.

• Processing of EO Coverages: WCPS and WPS. Develop WCPS for advanced

access to Earth Observation Coverages. Develop WPS for Earth Observation

data analysis of multiple coverages and other data.

GeosyncGeosync: Demo Scenario: Demo Scenario


Bulk Transfer CapabilitiesBulk Transfer Capabilities

• The proposed Geodata Bulk Transfer capability consists of a

conceptual 'container' where the 'parts' (defined below) function

independently of the whole container thus allowing potential producers

and consumers to leverage only part of the interoperability standard.

The 'container' should support the ability to:

1. Define the relationships between feature types

2. Maintain integrity (container check sums)

3. Provide a compression methodology optimized for transmission and

consumption on disadvantaged clients

4. Describe the parts or feature types within the container

5. Define the metadata for the whole container as well as the parts of the

container

6. Provide for direct random access (desirable but not mandatory)


GeosyncGeosync in OWSin OWS--8: additional considerations8: additional considerations

• Schema Initialization

– Enable creation of a new feature type in the data server through GSS

• Data Initialization: Ability to add and initialize features on server, prior to

geosynchronization

– Full Copy Data Initialization

– Partial Copy Initialization: similar to full copy data initialization except that a subset

of the source features is identified for geosynchronization (filtered on temporal, spatial

and scalar property constraints)

– No Copy Data Initialization (Point in Time Forward): geosynchronization can begin

at any point-in-time without the need to seed the target feature type with data from

the source feature type. The only requirement is that the target feature type exists or

is created using Schema Initialization. All future changes are integrated from the start

of no copy data initialization.

• Geosynchronization for Time Stamped, Time Sliced Data (WFS 2.0)

– Test spatio-temporal editing, filtering with GSS


Observation Fusion: Motion TrackingObservation Fusion: Motion Tracking

• Implementing and reconciling NATO STANAG and NGA MISB

standards for tracking moving objects in motion imagery, using OGC

Standards. Investigate, evaluate and recommend areas of

harmonization between OGC Sensor Web Enablement, OGC GML-

based standards, and OGC Tracking and Notification Service, to

support STANAG 4607 Ground Moving Target Indication Format

(GMTIF), Edition 3; STANAG 4609, Edition 3, EG0903.0 Video Moving

Target Indicator (VMTI); and NATO Study 4676 NATO ISR Tracking

Standard (NITS).

• Document a set of architecture viewpoints showing the use of SWE and

other OGC standards to implement the TCPED-based GMTI, VMTI,

and ISR Tracking concept of operations. Document any gaps and

shortfalls found in the architecturally relevant OGC suite of standards

where implementations supporting GMTI, VMTI, and/or ISR Tracking

would fall short of defined requirements. The OWS-8 ER on this topic

could become the basis for an OGC Best Practice.
