High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

private players who can generate the “theme maps” out of the base maps. Therefore
infrastructure development and growth of GT sector in a country are synergistically
related.
The National Map Policy, 2005
The Government of India, taking cognizance of the situation prevailing in the
geospatial sector promulgated, in the year 2005, a National Map Policy for India. In
broad terms, it seeks to reconcile the concerns of national security and the needs of
sustainable development. The twin objectives of the NMP are (i) To provide, maintain
and allow access and make available the National Topographic Database (NTDB) of
the SOI conforming to national standards; and (ii) To promote the use of geospatial
knowledge and intelligence through partnerships and other mechanisms by all
sections of the society and work towards a knowledge- based society. To ensure that
in furtherance of the new policy, national security objectives are fully safeguarded,
there will be two series of maps called the Defence Series maps (on Everest/WGS
84 Datum and Polyconic/UTM Projection) and Open Series Maps in UTM Projection
and WGS 84 datum. The OSM’s are primarily for supporting development activities in
the country and will have no VA’s and VP’s shown. The Ministry of Defence shall
give a one-time clearance to these OSM’s upon which they become unrestricted for
use and value addition in the open domain.
The volume of work
The creation of the NTDB on 1:10,000 scale is a mammoth task. This is quite
clear, even mechanically going by the number of sheets required to cover the entire
country against each scale, as given below;
