Gravimetric and astro-geodetic geoids and mean free-air anomalies in India
Abstract A preliminary gravimetric geoid with respect to the International Spheroid and the latest astro-geodetic geoid computed on the Everest and International Spheroids are given in the form of undulation maps over the Indian Sub—continent. $ 1^{0} $$ x1^{0} $ mean free-air anomalies (modified) on the Geodetic Reference System, 1967 (GRS-67) are also given for the whole country in the form of a chart. For the purpose of computing the gravimetric geoid, $ 5^{0} $$ x5^{0} $ mean free-air anomalies were used outside the area bounded by latitudes $ 0^{0} $ to $ 40^{0} $ N and longitudes $ 60^{0} $ to $ 100^{0} $ E and $ 1^{0} $$ x1^{0} $ mean free-air anomalies within these limits. The anomalies partly computed by Survey of India and mostly collected from other sources (such as B.G.I.) were utilised for this purpose. The astro-geodetic geoid is based on the astronomical data observed in India up to 1978.
