控制测量在数据处理时,通常要进行两次投影(地面→参考椭球面→高斯投影平面),也相应地产生两次投影变形,不利于大比例尺测图和工程施工放样。
When processing data in controlling survey , we usually project twice ( land surface → according to ellipsoid plane → gauss projection plane ) and it brings about Deformed projection twice too . It is not good for large scale mapping and setting-out of project construction .
