Abstract In an approximately 3 000 km2 hilly and semi-mountainous area of South China, 269 gravity points are measured to compare accuracy through various modelling types, algorithms and resolutions. Finally, the Bouguer gravity model anomaly model is calculated by the direct modeling method, and the accuracy was 1.7 mGal after the external coincidence test.
