Abstract:In this paper, data processing and precision analysis of GPSurban cadastration controlling network were carried out. In order to transform the geoid height into the normal height, the authors employed the dual polynomial curved surface function and constructed a height anomaly model for local area surveying. The final precisions of fitting points and checking points can attain the Grade-4 precision requirement and meet the needs of the cadastration work.
