Abstract: | Considering the differences in area, precision, datum and resolution existing among the national, provincial and urban quasi-geoids, some methods such as datum transformation and weighting according to precision are presented in this paper to normalize the quasi-geoid models with different areas, precisions, datums and resolutions. In this way, the seamless splicing of quasi-geoid is realized. |
