21st Century Indian Geodetic System, Distortion-Free Maps, Charts, and GIS

Dec 2005 | Comments Off

As India launches the DSMs and OSMs under its new map policy, it should not let the opportunity to slip by. The Timing could not be better to start producing the most accurate geospatial intelligence. The most accurate geodetic system with IAG recommended modeling is realizable in the very near future (Note: The GPS data collection over six Million square miles for the South American Geodetic System took a week to establish the fundamental framework).

New technique(s) are available to produce distortion-free maps, charts,

and GIS. GPS surveyed ellipsoid heights are the most ef?cient and cost effective vertical control and contours drawn with them on topographic maps and aeronautical charts will depict the real relief. For nautical charts, time-invariant ellipsoidal depths will provide the real bathymetry for safe navigation. All that is needed is to make a start and be ahead of everyone!
