Precision of the geoid, computed from terrestrial gravity measurements
Abstract
A method is developed to compute the precision of the geoid and of geoid differences from gravity measurements. The gravity values may have a variable quality and the density of the gravity networks in different areas may also be variable. This meets the reality. The method can also be applied for planning a gravity survey. Given the needed precision of geoid differences, the density of the gravity points can be estimated. On hand of table 1 the computation is very easy and can be done with a pocket calculator.
