Abstract

The GF-7 satellite has high spatial resolution. This article compares GF-7, GF-1 and GF-2 in terms of image color effect, spectral resolution and feature difference, and makes a preliminary evaluation of the accuracy of remote sensing geological structure interpretation and lithology information recognition based on GF-7 data. The results show that GF-7 can accurately identify geological bodies, and it can be used to carry out remote sensing geological information extraction from 1:5,000 to 1:20,000.
