| Abstract: | While drawing a topographic map,with regard to different geographical environment in different cities,a relationship was put forward between the quality of the map and other steps,such as air photography,data processing and survey controlling when large scaled digital map was used.Meanwhile,the relevant software and efficient operating procedure were fulfilled and some suggestions about how to guarantee the precision of the map and how to solve the practical problems were proposed. |
