Introduction To Hi-tech Survey
Hitech Survey is a process of survey through Modern Technology like Aerial
Photography, High Resolution Satellite Imagery,Differential Global Positioning
System (DGPS), Electronic Total Station (ETS). In Odisha it is carried out under
Odisha Special Survey and Settlement Act and Rule 2012.
In our society, ownership of land has an emotional and social value. In an agrarian
economy like ours, it is treated as an instrument for economic growth. Ownership
of land not only provides socio- economic security but also invests its owner with
certain privileges. In view of the above, survey, preparation and maintenance of
record of rights are important facets of revenue administration particularly for
odisha which is predominantly an agricultural economy.
The survey and settlement operations are being carried out in the State by
following conventional methods which are time consuming, cumbersome and
exorbitantly expensive. The very purpose of survey and settlement is defeated if
the operation takes a long time as changes in the ownership and status of land
are a continuous process.
Odisha Special Survey and Settlement Act, 2012 has been enacted which
provides for undertaking survey and settlement operations in the State by
adopting modern technology to minimize the time span without compromising
quality, transparency and grievance redressal The plot wise survey of a revenue
village is done by preparation of map through modern technology inclusive of
base mapping, demarcation of plots and ground truthing. In this Act in order to
ensure and facilitate active participation of the Land owners, opportunities are
afforded to make self declaration of the lands owned or held by them before the
concerned Tahasildars. The Act provides three stages viz; preliminary preparation
of RoR, draft preparation of RoR and final publication of RoR.
In order to ensure efficient, accurate and transparent delivery mechanism and
conflict resolution in ownership of land, an inbuilt computerized and digital
system of maintenance of record of rights including map is essential. To
accomplish this task, adequate provisions are made under the Act for
engagement of technically qualified persons (Licensed surveyors) on outsourcing
basis to prepare maps to scale, update maps prepared in course of cadastral and
revisional survey, prepare record of rights in post mapping stage, facilitate inter
connectivity among revenue offices etc. The Odisha Special Survey and
Settlement Rules, 2012 provides elaborate procedure to carry out the purposes
of the Act and also envisages to issue technical guidelines with regard to method
of survey by modern technology, works to be done during different stages of
survey and settlement operations, the manner of maintenance and making
available the record of rights and map of a revenue village in digital form to
interested persons and the technical aspects of work of the Licensed Surveyor.
Difference between Hi-tech Survey and Traditional Survey
In traditional Procedure Survey were being made manually using Gunter chain,
Plane Table method, Prismatic Compass and Theodolite. It was time consuming
and more cost and man power required.
Through Hi-Tech Survey the map is prepared digitally with highest level of
accuracy which can be preserved and updated digitally and 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. This
Survey Process is less Time Consuming, Cost effective, and map prepared through
it is of high level accuracy.
Limitations of Traditional system of surveying
Survey operations are not regular- gap between records and field reality
Associated with human errors
Out dated method- Low level of accuracy
Areas above 10 degree slope can not be surveyed
Time consuming- gap between measurement takenand final output
Maps in paper form- difficulty in updation
Reference point of land were subject to displacement.
Advantages of re-survey using modern technologies
Maximum use of machines-errors due to human factors in survey and map preparation are negated
Availability of modern techniques which are more accurate, less time consuming and cost effective.
Coordinate based ground control points- no fear of misplacement.
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
These are of Three type
Pure ground method using ETS & DGPS.
Hybrid method using Aerial Photography and ground truthing by ETS & DGPS.
Hybrid method using High Resolution Satellite Imagery and ground truthing by ETS & DGPS. STEPS FOR RESURVEY
1. Ground control point (gcp) establishment – monumentation 2. Aerial photography or Tasking and acquisition of worldview stereo satellite
data, digitization of existing cadastral maps and authenticated up-to-date record of rights (RoR)
3. Orthoimage generation and ground validation 4. Georeferencing of cadastral map for village boundary and area
confirmation 5. parcel vector generation from ortho-image
6. Field validation of image derived parcel vector 7. Obscured area survey 8. Vectorisation and integration of mutation data up to the date of survey
notification 9. integration of field survey vector with image derived vector to 10. Generate the draft cadastral map 11. Finalisation of draft cadastral map
Establishment of Ground Control Point Network
Primary GCPs- 16 km x 16 km
Secondary GCPs- 4 km x 4 km
Tertiary GCPS- 1 km x 1 km
Primary and Secondary GCPs have permanent value and hence need to be preserved.
Appointment of Vendor/ Agency
The Director Land Record and Survey will appoint one or more vendor/agency
having technical qualification of Survey and Preparatin of map and ROR.
Acquisition of Stereo Satellite Data/ Aerial Photographs
Satellite data need to be procured from National Remote Sensing Agency, Hyderabad.
In other case the aerial photographs need to be taken by low flying aircrafts loaded with GPS and high resolution camera.
Geo-referencing of Sabik Digital Cadastral Map and delineation of Village boundary on the ortho-image
After completion of Geo-referencing, the Survey Team will delineate the Village Boundary on the ortho-image; adjust, if required, the boundary vector at, Edge Plots to ensure that it runs on the physical demarcation features and finalize the Village Boundary on the image. The area computed from the newly generated Village Boundary should be confirmed by the competent authority.
Preparatory work for Ground truthing and Obscure Area Survey
Obscured areas and Gharabari Plots are to be surveyed on Ground using ETS/ DGPS based on locally available GCPs after demarcation by concerned Rl/ Amin in presence of land owners/enjoyers.
Vectors generated from Ortho-Image & DGPS/ETS survey are to be integrated to prepare draft Village Map.
Comparison of village area of cadastral map, ortho-image and RoR data
Maximum tolerable limit – 2% between different sources of village area
For the purpose, RoR data should be up to date
In case of variation (above 2% tolerable limit) field survey is necessary for boundary demarcation.
Field survey is necessary if the village boundary falls under obscure areas or incase large scale variation in the village boundaries. The area obtained from filed survey will be treated as final
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 schedule with area and corresponding Sabik reference in Form No.06 (T) to the Tahasildar.
QUALITY CHECKING :
The QC checks will be done by ORSAC QC team in following stages or as when required:
After generation of ortho-image.
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.
After plot vector generation and prior to ground truthing/verification:
Digitised cadastral maps of one tahasil georeferenced and verified
The geometry of parcels, the village boundary, matched andmismatched plots as seen on the image.
Before submission of Draft Map to Tahasil for verification: The village incompleteness, correctness of matched and mismatched parcels as identified by the vendor.
Before final submission: Village map as a whole and the statistics after
RoR linkage and 'Khanapuri Operation'.
Some of the bund dimensions will be verified by ORSAC for ensuring correctness and quality of survey by the vendor.

Progress in Odisha
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
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
