Abstract
In this investigation 15 different methods of the computation of mean anomalies of 1° x 1° blocks were examined and compared in a limited test area. The purpose of the study was to find an economical method of the computation of mean anomalies for the blocks in which some observed gravity values were given with corresponding location and elevation information. The mean elevation of the 1° x 1° block was also assumed to be known. As a result of the tests, five out of 15 techniques were found to be usable for the prediction and they were about equal in accuracy. The economy of the computations was also considered in the final recommendation about the best technique to be used. The effect of uncertainty in b-coefficient on predicted anomalies was examined. A simple formula for estimating the effect was given.
