The Survey of India (SOI), the national
survey and mapping organisation set up in 1767, is the National
Principal Mapping Agency.
The Survey of India bears a special
responsibility to ensure that the country’s domain is explored
and mapped suitably to provide base maps for an expeditious and
integrated development and ensure that all resources fully contribute
their mite for national progress, prosperity and security.
The primary responsibility of
SOI is to maintain topographical map coverage.
The topographical map coverage covering
the entire country has been completed. The map sheets are updated
at regular intervals to depict the latest spatial information.
While the Survey of India meets
the national needs in cartography, some specialised thematic maps
required to meet the needs of the specific users are taken care
of by the National Atlas and Thematic Mapping Organisation (NATMO).
It also concentrates its attention
in a number of areas to integrate resource maps with other relevant
socio-economic data and represent them in spatial forms, useful
for developmental planning. (PIB Features).
