DATA TRANSFORMATION
Existing Horizontal Datum was defined based on the Great Trigonometrical Survey done between 1802 to 1841
Existing Vertical Datum was defined in 1905 without gravity observations
To meet the present requirement of higher centimeter level accuracy, the datum require further refinement.
Redefinition of Indian Geodetic Datum is underway. For defining the Horizontal Datum, 300 GCPs established earlier further densified with additional 2200 GCPs .
To Redefine the Vertical Datum, more than 44,000 linear km of High Precision Leveling has been completed .
Redefinition of Geodetic Datum
Geomagnetic Surveys• SOI Prepares Magnetic Declination Charts• SOI shares the data with Indian Institute of Geomagnetism
(IIG)• The magnetic observation made at Magnetic Observatory,
Sabhawala, are published in yearly bulletin since 1964• The geomagnetic elements are useful in prospecting for
minerals and natural resources• Their variations may be precursors or indicators of the
likelihood of seismic activity
Tidal Observations
• SOI has been carrying out tidal observations for more than 125 years
• Tide Tables giving the predicted values of tides are published every year
• The Tide Gauge Network are modernized by equipping the tidal observatories with real time data transmission facilities
• Tidal data is received on real time at National Tidal Data Center
• This data is useful for determination of MSL, scientific studies and Tsunami Warning System.

Survey Work in Antarctica
• SOI has been participating in Indian Expedition to Antarctica since 1990-91
• Started Surveying, mapping and scientific studies in Schirmacher Oasis, Antarctica
• A new second station is proposed at Larsemann Hills. SOI was asked to prepare the map of that area during 2006-07
• Accordingly Map on 1:2,500 scale has been prepared.
National GIS Objectives
• A seamless nation-wide GIS ready database.• To serve as a platform for G-Gov• State of art Data/Apps hosting environment• Enabling service provision for different user
groups.• To capture and assimilate data owned by public
owned agencies, create a data platform and develop demand driven GIS products to promote G-Gov.
NGIS- Data Asset Building Plan
• To start immediately, NGIS Data Asset will be built based on 1:50k Geospatial data of SoI.
• secondly, this will be replaced/ upscale with 1:10k data
• Advantages:– Meets some immediate requirements and also makes all
agencies of Govt aware of NGIS and it’s importance– Many technical procedures get established – Can be achieved in 1 year time.– Scope for incorporating better methods and ideas for
developing full scale data asset on 1:10k

1:10K MAPPING• 1:50,000 scale, it is not possible to depict utility buildings like hospitals,
schools, police stations, post offices etc
• On 1:10,000 scale, all such buildings can be comfortably depicted.
• Microzonation for Disaster Management requires 3D base maps on scale 1:10,000.
• In assessing natural resource endowments, agricultural practices, grazing lands, village forests, which are essential for rural development can be shown on scale 1:10K.
• Security forces expressed need for maps on 1:10K / 5K scale for the whole country.
• Increase of population the cost of land/property is increasing exorbitantly creating Demand for large scale maps and the requirement of the accurate control ,
Re-engineering of 1:50K Data
• Generation of GIS enabled 1:50k foundation data from OSM DTDB database.
• To meet the immediate spatial data requirement of NGIS Version-1.0 to operationalize the NGIS Asset.
• Enable integration of data owned by multiple agencies.
Re-engg of 1: 50k cont……
• The re-engineered data will be transferred to a robust, secure, enterprise level RDBMS like Oracle.
• further processed for delivery as interoperable Web Feature Service (WMS/WFS) in OGC's Geography Mark up Language (GML) version 3.2.1 (ISO 19136:2007) format.
• The metadata information implicit in the annotation layers and auxiliary files associated with the data also will be extracted and structured as per NSDI standards .
• Web Catalog Service is also to be created.
Establishing Data Centres• The production system in SoI is PC based. • Data moves back and forth several times from every
SOI state centers to centers like NGDC and GIS & RS for QA/QC, Cartographic symbolization etc.
• Shipment of data occurs in offline mode – generally in CDs and HDs generating multiple copies of the same data .
• Virtually there are lots of duplication in processes to meet every demand resulting in huge wastage of time, effort and resources.
• Security of data being a manual exercise gets compromised.

Virtual Reference System (VRS)• VRS offers highly accurate, alternate DGPS service as a
solution to positional accuracy problems.• VRS involves Continuously Operating GPS Reference
Stations (CORS), at spacing up to 50 to 60km. CORS feed their GPS data to a central processing computer via a computer network.
• The user makes a mobile phone call into the central processing facility, supplying its approximate position (based on a GPS navigation position) and request for corrections.
• The central processing computer generates corrections as though there is a reference station at the approximate coordinates of the rover's position and the rover is positioned relative to this VRS.
• The Virtual Reference Station (VRS) concept is an extension of the so-called real time kinematic (RTK) technique developed for GPS surveying and other forms of high precision positioning.
• With RTK, one can establish a base (or reference) station at a known point and broadcast the data from the reference station to one or more roving receivers.
• The computer processor at the roving receivers (usually in the hand held data recorder or survey controller) combines the reference station data with the rover data.
• With modern equipment, only a few epochs of data are typically required to fix the ambiguities associated with the GPS phase data observable and compute a GPS baseline; the difference in latitude, longitude and height between the reference and rover positions
Processing & Control Centre
Pilot project for VRS• The location of reference stations has been selected in such a
way that they fall in the most developed areas of the above three states.
• The radial distance between two adjacent stations has been kept within 50 to 60km.
• Total 32 reference stations will be established in the first phase of the project in the three states Odisha, Andhra Pradesh and Gujarat. For establishment of reference station available GCP Phase-I or GCP Phase-II locations will be selected whose coordinates have been computed and standardised with reference to a particular ITRF at a particular epoch.
• The Control station will be located at Geodetic & Research Branch, Survey of India, Dehra Dun.
