METHODS FOR FITTING LOCAL QUASIGEOID AND THEIR APPLICABILITY ANALYSIS
摘要
Abstract
The character and applicability several fitting methods for refining local quasigeoid are systematically analyzed in some examples which have the different area, the terrain complexity, the diverse accuracy of GPS/leveling data and the various resolutions of gravity quasigeoid. Finally, those methods are applied successfully in three typical projects of refining quasigeoid, and the good effects are obtained.关键词
