Research on 1∶10000 Basic Surveying and Mapping Production Based on Gaofen-7
Gaofen-7 is the first sub-meter resolution civil stereo mapping satellites in China. According to the design requirements, Gaofen-7 satellite can meet the civil 1∶10000 scale map production requirements by using satellite image stereo mapping. Based on this, Altai region of Xinjiang was selected as the survey area, and GaoFen-7 satellite images were obtained in this paper. Different control point layout schemes are adopted to adjust the regional network. With the check points and scattered points measured in the field, the adjustment results of regional network are tested and the optimal control point layout scheme is proposed for the terrain type of flat area. This provides reference and support for the popularization and application of Gaofen-7 in 1∶10000 scale basic surveying and mapping products.
