Introduction:

Till date cadastral maps were being prepared as per the provisions of the odisha

survey & settlement act, 1958 which recommended for survey and settlement

operation in the state through 4 methods of survey. Such as;

(a) Theodolite traverse

(b) Prismatic compass traverse

(c) Plain table traverse

(d) Chain triangulation method

These processes are resource hungry (time, cost&man power). Besides

accuracy levels have been very low in those traditional methods of survey.

With the advancement of science & technology, there have been scopes for

use of modern survey equipment &methodology to bring efficacy in survey &creation

&updation of land records with in short time span with perfection & accuracy

compared to old method of survey & record preparation. The odisha special survey &

settlement act 2012, has been enacted by the government of odisha for such hi-tech

survey to minimize the time span without compromising quality, transparency and

grievance redressal with involvement of minimum manpower.

Difference between Traditional Survey & Hi-Tech Survey:

Traditional Survey Hi-Tech Survey1. In traditional Procedure Survey

were being made manually.

2. Re survey is required.

3. Gunter chain, Plane Table

method, Prismatic Compass and

Theodolite are used.

4. It was time consuming.

5. It is more costly and man

power required.

1. Through Hi-Tech Survey the

map is prepared digitally with

highest level of accuracy which

can be preserved and updated

digitally.

2. Re-Survey is not required. The

map is Co-ordinate based

having latitude and Longitude

of each point or location of the

village which helps in post

survey demarcation.

3. This Survey Process is less Time

Consuming.

4. It is more Cost effective,

5. The map prepared through it is

of high level accuracy

Limitations of Traditional system of surveying:

1. Survey operations are not regular- gap between records and field reality

a. Associated with human errors

b. Out dated method- Low level of accuracy

c. Areas above 10 degree slope cannot be surveyed

d. Time consuming- gap between measurement taken and final output

e. Maps in paper form- difficulty in updating

f. Reference points of land were subject to displacement.

Page-3

2. Advantages of re-survey using modern technologies

a. Maximum use of machines-errors due to human factors in survey and map

preparation are negated

b. Availability of modern techniques which are more accurate, less time

consuming and cost effective.

c. Coordinate based ground control points- no fear of misplacement.

d. Final output in digital form- further updation.

How is Hi-Tech Survey being conducted? Role of Revenue Officials in verification,

validation, and preparation of RoR and maps (under Odisha Special Survey and

Settlement Act & Rule, 2012)

Methods used in Hi-Tech Survey:

There are three types of methods used for hi-tech survey, such as;

1. Pure ground method using ETS &DGPS: The method is suitable for small tract

&where plots shapes are large & with relatively straight boundaries.

Pros: It offers most accurate result of land parcel measurement.

Cons: Very expensive in case of small &irregular sized plots.

2. Hybrid method using aerial photography & ground truthing by ETS &DGPS.

Under this method, low flying small aircrafts fitted with GPS & high resolution

cameras are used to take the images of the ground but due to obstructions

between the camera & the ground surface like bushes, trees etc. Some plot

boundaries become difficult to decipher. Therefore, it needs supplementation

by use of DGPS/ETS.

Page-4

Pros:

Suitable for large tract of areas.

Image quality superior than satellite imagery.

Plot level vectorisation will be accurate.

Cons:

Suitable weather condition is required for flying aircrafts- images can be

obtained during limited period of the year.

3. Hybrid method using high resolution satellite imagery & ground truthing by ETS

& DGPS.

The method is high resolution satellite imageries are obtained. However, like

aerial photography method, supplementation by use of DGPS/ETS will be

required due to obscured areas in satellite imagery.

Pros- Suitable for large tract of areas.

Cons- Image quality is inferior as compared to aerial photography.

Steps to be followed for undertaking survey operation:

1. Establishment of ground control point network

a. Primary GCPs- 16 km x 16 km

b. Secondary GCPs- 4 km x 4 km

c. Tertiary GCPS- 1 km x 1 km

d. Primary and Secondary GCPs have permanent value and hence need to be

preserved.

Page-5

2. Acquisition of Stereo satellite images

a. Data need to be procured from National Remote Satellite Sensing Agency,

Hyderabad.

b. In other case the aerial photographs need to be taken by low flying

aircrafts loaded with GPS and high resolution camera.

Page-6

3. Validation of ortho image

The ortho image are validated by ORSAC following tie-line measurements

taken on the Ortho image in the laboratory & the corresponding ground using

ETS/DGPS for those points in the field.

4. Digitisation of cadastral maps

All maps of any revenue village are first digitised & mosaic to create the

complete village mosaic in the auto CAD environment. After preparation of

digital files, a printout map is taken in the original map scale & verified with the

original maps on glass table with tolerance accuracy of 1mm. Any error found

during this checking need to be rectified in the digitised map.

5. Delineation of village boundary over ortho image.

Village boundary polygon after being digitised is super imposed over the ortho

image matching the cultural features/plot polygons within the village which

have not been changed in the field over a period of time & are accordingly

clearly visible both in the ortho image as well as in the digitised cadastral map.

Generation of Draft Village Map and RoR :

After compliance of the orders of the Camp Officer/ Tahasildar relating to one

Village, the survey team shall furnish Village Map complete with integration of

textual data,plot schedulewith area and corresponding Sabik reference in Form

No.06 (T) to the Tahasildar.

Quality Checking:

1. The QC checks will be done by ORSAC QC team in following stages or as

when required:

2. After generation of ortho-image.

3. After geo-referencing of 'Sabik' cadastral maps with the image:

Georeferencing of individual parcels and the village as a whole for

delineation/demarcation of village boundary.

4. After plot vector generation and prior to ground truthing/verification:

Page-7

Digitised cadastral maps of one tahasil geo-referenced and verified:

1. The geometry of parcels, the village boundary, matched & mismatched

plots as seen on the image.

2. Before submission of Draft Map to Tahasil for verification: The village

incompleteness, correctness of matched and mismatched parcels as

identified by the vendor.

3. Before final submission: Village map as a whole and the statistics after

4. RoR linkage and 'Khanapuri Operation'.

5. Some of the bund dimensions will be verified by ORSAC for ensuring

correctness and quality of survey by the vendor.

Progress of Hi-tech survey in Odisha –A case study of Deogarh District:

The odisha government has been conducting piloting high-tech land survey in

nine districts suchas;Cuttack, Khorda ,Keonjhar ,Bolangir, Deogarh,Subarnapur,

Sambalpur, Ganjam & Sundargarh. However, 4 districts are postponed for

certain period where as 5districts like Sambalpur,Bolangir, Deogarh,

Sundargarh& Subarnapur are in progressing phase. The State Government has

decided to roll it out to other districts. The Revenue department has been

Page-11

directed to work out a detailed project report (DPR) for undertaking high-tech

survey of the land in the entire State.

Meanwhile, Record of Rights (RoR) of all 51,675 revenue villages have been

computerised and put online in Bhulekh website. Maps of 51,612 villages have

been also digitised and uploaded in the website.Modern record rooms have

been developed in 279 out of 317 tahasils and steps have been taken to

develop similar facility in rest of the tahasils.

Conclusion:

After successfully piloting high-tech land survey in nine districts, the

State Government has decided to roll it out to other districts. The Revenue

department has been asked to work out a detailed project report (DPR) for

undertaking high-tech survey of the land in the entire State.

A sub-committee was formed under the chairmanship of Principal Secretary IT

P.K. Jena to look in to storage, security and usability of the data.

Representatives from National Informatics Centre (NIC), Directorate of Land

Records, Odisha Remote Sensing Application Centre (ORSAC) and Odisha

Computer Application Centre (OCAC) are members of the committee.

Meanwhile, Record of Rights (RoR) of all 51,675 revenue villages have been

computerised and put online in Bhulekh website. Maps of 51,612 villages have

been also digitised and uploaded in the website.

.Presently, re-survey work of the land records through modern technologies

have been taken up in 9 districts namely Cuttack, Khordha, Ganjam, Keonjhar,

Deogarh, Sundargarh, Bolangir, Subarnapur and Sambalpur
