| Abstract: | The method to interpolate the quasi-geoid of GPS leveling using application software CASS to create digital terrain model of height anomaly and draw its isolines is introduced in this paper. To compare this method with several methods of curved surface interpolation, this has better interpolation effects and is easy to use in practical engineering applications. |
