| Abstract: | Taking certain areas of the project as an example, through the statistic of project workflow, the detail of operation of each period, project progress, and accuracy parameter, this paper explores the application of ADS digital aerial photography system which carries out mapping and image extension using small amount of image control points and reduces the work load and cost of field control surveying, and whose surveying result meets the requirement of large scale topographic map. The application of ADS 80 accelerates production progress and shortens mapping cycle. |
