PREDICTION OF 1'x1° MEAN FREE-AIR GRAVITY ANOMALIES . USING COVARIANCE FUNCTION FOR THE CONTINENTAL PORTION OF INDIAN REGION

Abstract

In physical goodosy for tho dotoraination of Geoid by graviastrio method, t rot uiro gravity data in the fora of amity onopallos at evory pointo of tho oarth,0 curface• Though gravity is a mossurablo quantity, it is imposolblo to make measuromonts for tho ontiro earth's surface. Consoquontly t have to obtain the Gravity data by some method of prodic-tion for the moos where Gravity measuromonts have cot boon °ado or whore it is not poosible to mak° messuromonts, Although thorn rro soma methods for the pro4iction of gravity anomalies in tho presont work tho Loact :4onrss Tochniquo using covariance function of gravity anomolloo has boon ooployod to predict tho lf/x 1 on froe-air gravity anomalios in uravimotrioally void areas of continontol por Lion of India, It has boon found that tho method ucod for tho prediction elm satisfactory moults es the averoao otandard orror of prodiction is in 10 Mails
