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!
