Annual Report 1999-2000
Survey of India
Survey of India, with its headquarters at Dehra
Dun, has been charged with the responsibility of preparing
various types of maps on various scales and generating the
topographical data for the last 233 years. It bears a special
responsibility to ensure that the country's domain is explored
and mapped suitably to provide base maps for planners, administrators
and academicians and ensure that all resources contribute
their full measure to the progress and security of the nation.
Besides, it has also been carrying out Geodetic and Geophysical
Surveys and allied research work in the areas of tidal, gravity,
geomagnetic and project surveys for tunnel alignment, crustal
movement and dam deformation studies etc. Some of the highlights
during the period under report are as under:
Technology Development Projects
i) Modernization of Tide gauge network along
Indian Coast line and Islands is in progress under Sea-level
Monitoring and Modeling (SELMAM) Project assisted by the Department
of Ocean Development (DOD). Tidal data from Acoustic Type
Tide Gauges and Float Type Digital Tide Gauges installed at
various parts is being generated and received at National
Tidal Data Centre, Dehra Dun for processing and analysis of
ii) A Standing Committee for Cartography under NNRMS is working
out the procedure and specifications of a National Spatial
Data Infrastructure aimed to enable users to access a standard
cartographic database for superimposing their thematic information
for research and analysis in GIS environment.
iii) The following Projects are in hand in Digital Mapping
- Formulation and Updation of Standard Operating Procedures
(SOPs) to standardise the procedure for preparation of DCDBs
on 1:250,000 and larger scales.
- Standardisation of symbols to be used in topographical
maps compatible with digital techniques.
- Development of GRAM-GIS Package for use in rural development
in collaboration with IIT, Mumbai under NRDMS programme
Basic Research Projects
(i) Geodetic and Geophysical
- Data generation and its processing for redefinition of
Indian Geodetic Datum.
- Adjustment of Second Level Net of India to refine Vertical
ii) Oceanographic work
- Analysis of Tidal Data for updating the Tidal Constituents
for using these for improvement in prediction of Tides.
- Maintenance of National Tidal Data Centre and receiving/
processing of tidal data of various ports.
Technologies Transferred/ Commercialised
i) Proposal for setting up a Geomatics Centre
at Delhi for the purpose of making the digital/ geographical
data available to public and other organisations engaged in
development planning has been submitted. This will enable
scientists and planners of various Government and Non-government
organisations to extract useful information from the digital
data base and model it in desirable formats. Besides imparting
job experience to the participants, the centre will earn revenue
for its sustainability.
ii) Technology for indigenous production of Photo opaque as
an import substitute item for touching of film negatives has
been developed in collaboration with Indian Institute of Chemical
Technology (IICT), Hyderabad. The production of photo opaque
is being supplied to various Survey of India Directorate/
iii) The production of touch-up fluid again an import subsitute
item, required to correct scribed originals is being undertaken
in R&D directorate for using within the department.
Technology Demonstration Projects Undertaken
in the Area of Socio-Economic Development
i) District Planning
Map Series - A project on preparation of district planning
maps containing thematic information is continued. 135 maps
have been printed out of 249 maps covering half the districts
of India. Districts planning maps for remaining half of the
area are being processed by National Atlas and Thematic Mapping
Organisation (NATMO). These maps are being utilised by the
Government, non-government organisations and private agencies
in socio-economic development of the nation.
ii) Coastal Mapping - Coastal
mapping along the Eastern coast line has been in progress
to study the effect of submergence due to rise in sea-level
and other natural phenomenon. Ground surveys have been completed
for the proposed coastal region and maps are under printing.
iii) Geodetic surveys : Geodetic
surveys for tunnel alignment and other structures such as
Dam, Power House Complex etc. for Tala Hydro-Electric Project
in Bhutan had been in progress. Large scale surveys and mapping
on various scales for about 27 developmental projects have
also been in progress.
- Geodetic and Research Branch (G&RB)
is responsible for carrying out Geodetic Horizontal and
Vertical control for national mapping programme. Tidal,
gravity and magnetic observations across the country for
various scientific studies and control for the project surveys
involving tunnel alignments, dam deformation studies, crustal
movement studies etc. During the year, the Geodetic and
Research Branch (G&RB) is committed to provide 350 GPS
stations, 3140 lin km of high precision/ precision leveling
besides gravity and geomagnetic observations as departmental
i) Geodetic & Geophysical Surveys viz. Tidal
observations, Gravity observations, Geomagnetic observations,
Tunnel alignment, Crustal movement studies have been carried
out in the states of Andhra Pradesh, Goa, Karnataka, Kerala,
Tamil Nadu and Daman and Diu to generate data for further
research work with regard to seismic and seismotectonics activities,
in earthquake prone areas.
ii) With the operationalisation of Digital Mapping Centres
in the department, several application softwares have been
developed to create DCDBs for value added digital products.
Some of the S/W developments are listed below:
- Development of Programme for DVD-1 format to DGN format
and DGN format to DVD-1 format.
- Development of S/W for conversion of DRW formats to DGN
- To demonstrate the capability/ feasibility of the digital
environment regarding digitisation of tidal charts, interpolation
and error correction.
- A team of two officers from Survey of India participated
in the 18th Indian Scientific Expedition to Antarctica.
The objective of this team was to provide precise ground
control points for Geographical & Geophysical field
work and densification of the Topographical control (Horizontal
& Vertical) in the area covering additional base stations
for carrying out contoured mapping at 1 M vertical interval.
Two officers from Survey of India will participate in the
19th Antarctica Expedition during October 1999 to March
Any Other Information
i) International Boundaries
Demarcation, Relocation and Construction of boundary pillars
and preparation of Strip-Maps of Indo-Nepal, Indo-Pakistan
and Indo-Bangladesh boundaries remained in progress during
