Title: | 深圳市1km高分辨率厘米级高精度大地水准面的确定 | Other Title: | Determination of Shenzhen geoid with 1 km resolution and centimeter accuracy | Authors: | Ning, JS Luo, ZC Yang, ZJ Chen, YQ Zhang, TJ |
Issue Date: | 2003 | Source: | 測繪学报 (Acta geodetica et cartographica sinica), May 2003, v. 32, no. 2, p. 102-107 | Abstract: | 利用65个精度优于2cm的GPS水 准数据、5213个实测重力点数据、100m分辨率的数字地形模型和WDM94地球重力场模型,采用移去 恢复技术计算了深圳市1km分辨率的大地水准面模型。将该模型大地水准面高与由29个GPS水准得到的大地水准面高进行比较,其差值的标准差 为±1.4cm。 The geoid of Shenzhen with one kilometer resolution, has been constructed with remove restore technique, using 65 GPS/leveling data with accuracy better than 2 cm, 5 213 discrete gravity data, digital terrain model with 100 m resolutions and global earth’s gravity field model WDM94. The modeled geoid heights were compared with the observed ones derived from 29 GPS/leveling data that not applied to the construction of Shenzhen geoid. The test results show that the standard deviation of the differences is ±1.4 cm. |
