1) regional ellipsoidal surface
区域性椭球面
1.
In adjustment and transformation for engineering GPS control networks,we should adopt a regional ellipsoidal surface which is in conformity with the reference level for the reduction of side length(projection surface) in survey area,so that an indentical scale for projecting of space side between GPS and the terrestial network can be achieved.
在工程GPS网的平差转换中 ,为使GPS网与地面网在空间边长投影方面取得相一致的边长尺度 ,须选用一个与地面网边长归算高程基准面 (以下简称为投影面 )尽可能贴近的区域性椭球面 。
2.
The regional ellipsoidal surface is more coincidental with the surface of mean height in the region.
这种椭球面DTM是在区域性椭球面上基于测地坐标系建立起来的 ,因此不同于基于投影平面的现有的DTM 。
2) Elements of the regional ellipsoid
