Specifications and requirements of topographic survey and the whole survey process

First of all, the mapping process of topographic map can be old-fashioned flat drawing, and it can also refer to the field part of aerial or aerospace photogrammetry. In addition, the process of making topographic maps with different scales is different. Therefore, search for "topographic flat survey specification" and "topographic aerial photogrammetry field specification", and pay attention to the scale.

If necessary, I will upload the last version of these standards, and the new version of aerial survey is being worked out.
