| Abstract: | The detail method was introduced for application of quasi-geoid model to GPS height converting in the earth's surface of main urban region of Haikou. It's proved when we take suitable surveying method to apply quasi-geoid model to GPS height converting in the earth's surface of main urban region crowded with man、vehcle and building、electric power、communication facility,so that the results can be satisfied with the demand of grade-height control for related standard,the manual labor、material and financial resources decreased and the surveying work efficiency raised. |
