Application of GF-14 satelliate hyperspectral image in shallow sea depth inversion
At present,the spaceborne hyperspectral water depth remote sensing inversion application is mainly based on foreign satellite data,and the research and application of domestic satellite data are sparse.To explore the potential of shallow sea depth inversion in domestic high resolution satellite hyperspectral images,we use the domestic GF-14 satellite image.We also take the west island of Sanya Bay as the test area to study the water depth inversion ability of hyperspectral image and to establish the dual-band ratio water depth inversion model through the measured water depth points and ICESat-2 lidar data processing.The results show that the GF-14 hyperspectral images have good shallow water depth inversion ability and inversion accuracy.The paper will provide reference for the domestic satellite to carry out the space-borne hyperspectral data water depth inversion research.
