ABOUT, SURVEY OF INDIA
SURVEY OF INDIA IS THE NATIONAL
MAPPING AGENCY OF OUR COUNTRY.
• IT IS THE OLDEST SCIENTIFIC
DEPARTMENT OF GOVT OF INDIA.
• IT WAS SET UP IN 1767 AND HAS
CREDIT OF OVER 247 YEARS OF
GLORIOUS SERVICE TO THE NATION
SOI - VISION
SURVEY OF INDIA TAKES
IN PROVIDING CUSTOMER FOCUSSED,
COST EFFECTIVE AND
INFORMATION AND INTELLIGENCE
FOR MEETING THE NEEDS OF
SECURITY, SUSTAINABLE NATIONAL
DEVELOPMENT AND NEW
All Topographical Mapping, Providing Ground
Control, within AOR.
Mapping and Production Of Geographical maps
and Surveys for Developmental Projects.
Large-scale mapping, Cities, Guide Maps &

OSM (1:50K Scale) :- Complete
DSM (1:50K Scale):- Complete
1:25, 000 Scale Map Digitization :- Undergoing
State Map of Jharkhand (Hindi & English Edition) :- Completed and released
in public domain by Hon’ble Governor of Jharkhand during Mar 2012.
Ranchi Guide Map : Undergoing
NUIS Project : Data Sent to SNA but again taken back for Attribute collection
of Core area.
Coal Mine/CMPDI Project : Undergoing
Supply of DATA (Lat, Long, Bearing, Height etc.) to Indenters: Continuing
Supply of Data to Indenters
Applications are received from Indenters for Supply of
Certificates/Data for Coordinates, Aerial Distance, MSL
Heights and Bearing etc for obtaining their project
clearances from competent authorities of State/Centre.
On receipt of full payment , as prescribed Govt. rates, the
same is processed on first come first serve basis.
The Certificate/ Data are supplied as per prescribed
format at the admissible degree of precision.
ABOUT PROJECT ‘NLRMP’
This integrated programme envisaged by the
Government of India and to be implemented
by all state governments, would modernize
management of land records, minimize scope
of land/property disputes and enhance
transparency in land record management
system enabling e- Governace
Develop a modern, comprehensive and
transparent Land Records Management
System in the country.
No doubt, It will be an essential tool for e-Gov
To implement the conclusive land-titling
PRINCIPLES BASED UPON
A single window to handle land records
including the maintenance and updating of
textual records, maps, survey and
settlement operations and registration of
The Mirror principle - which refers to the
fact that cadastral records mirror the
PRINCIPLES BASED UPON
The Curtain principle – which indicates
that the record of title is a true depiction of
the ownership status, mutation is
The Title Insurance- Which guarantees the
title for its correctness and indemnifies the
title holder against loss arising on account
of any defect therein.
LIKELY STAGES OF WORK
Scanning of old records, maps.
Geo- referencing High Res Image data and processing for
feature extraction using sufficient number of Precise
Ground Control points .
Digitization of features.
Selection of Scale, Projection, Datum etc with an aim to
fit the data on National framework for seamless
Linking the attributes.
Capacity building for the project executing agencies
QA/QC capability in domain like Digitization, Elevation
generation and other aspects of map design .
Use of Geospatial tools like GPS/DGNSS, Total station, Digital
Levels etc for provision of thousands of ground Control
points (x, y, z) with mm of accuracy.
Updating of these Data at certain interval.
Training and maintenance of data
USE OF ‘VRS’/ ‘CORS’ TECHNIQUE FOR NLRMP PROJECT
• Accurate locations are needed at village/town/city level
for survey . Thousands of such control points are required
in entire country. The accuracy requirement is in the order
• To complete such a huge task in a country like India,
several years are required with the present available trained
manpower and technique of post processing based GPS
• However, this task can easily be fulfilled by establishing a
n/w of Real Time Kinematic (RTK) infrastructure i.e., Virtual
Reference Stations (VRS) which is also known as
Continuous Operating Reference Station (CORS) Network.
DIFFERENTIAL GPS THROUGH MULTIPLE N/W REF STN
(CALLED VIRTUAL REFERENCE STN, VRS)
1. Each reference station is equipped with
one dual frequency receiver which
continuously feed their GPS data to a
central processing computer (Control
Centre) via computer network.
2. The central processor uses the ref
stations’ data to model the spatial error
and generate appropriate correction.
3. The Rover station working in the area by
getting this correction through mobile
link and applying the same, gets very
accurate positioning in real time.
4. Continuous operating reference station (
CORS ) are placed at a spacing of 50 – 60
5. The accuracy achieved in positioning is
of the order of 1 cm. and Neither time
nor distance is the limiting factor for
OBJECTIVE OF THE ‘ CORS ’ PROJECT
• Objective of the project is to convert some of the
GCPs already established throughout the country as
Continuous Operating Reference Stations (CORS)
which will provide centimetre level accurate real time
positioning, using low cost single frequency
GPS/GNSS receiver to numerous users using the
Area Correction Parameter (ACP)/VRS concept.
Nearly 30 Such points are proposed to be
established in Jharkhand state. These points have to
be established in secured place/campus for which
suitable places will be requisitioned from state Govt.
INITIATIVES BY SOI
• SoI provides Horizontal and Vertical Ground control points for
mapping as well as for various infrastructural projects such as
development of Railway, Road and Irrigation network, drainage
system, township development, navigation, power projects etc.
• In this endeavour, G&RB Dte of SoI has already provided about
2500 Ground Control Points (GCPs) covering entire country
(Mainland as well as Islands).
• 65 Such GCP,s are existing in Jharkhand state for which data
has been provided to State Govt, which may be utilised for
projects like NLRMP etc.
SOI proposes to establish CORS (Continuous Operating
Reference Stations) Network to provide real time precise
positioning with single frequency/cheaper GPS receiver for
OTHER APPLICATION AREA OF ‘CORS’
• Transport and communication management
• Real Time Kinematics (RTK) applications for thousands of GPS
• Differential Global Positioning System (DGPS) applications
• Monitoring of Crustal movement/ Tectonic plates in India and
• Combination of the GPS derived ellipsoidal heights with a precise
Geoid model to replace conventional leveling.
• Land Surveying, Cadastral Surveying, Airborne Photogrammetry,
Geographical Information Systems (GIS)
• Applications in the public supply services (power, gas, etc.)
• Fleet Management , Precision Farming etc.
• Hydrographic Surveys , Environnemental Applications etc.
