THE GF-2 CAPABILITY ANALYSIS IN SHALLOW WATER REMOTE SENSING BATHYMETRY

This paper takes the domestic GF-2 remote sensing image as the data source, on the basis of data preprocessing, we establish a single-band regression model, a dual-band ratio model and a multi-band regression model, perform the bathymetry on the sea of the study area, and compared with WorldView-2 data. The results show that, in general, the dual-band ratio model has the best inversion, followed by multiple bands and the worst single-band;The inversion accuracy of GF-2 and WorldView-2 is not very different, explain that GF-2 can replace the expensive WorldView-2 data to some extent for bathymetry.
