| Abstract: | This article expounds the detecting techniques of the city quasi-geoid’s internal and external accord accuracy in Chenzhou.The test results show that city quasi-geoid’s precision is less than 2 cm,which can completely replace the work of fourth and even third leveling surveying.Its spread in application changes the traditional mode of height survey,and it could bring in enormous benefits in economy. |
