摘要
With the development of information technology, traditional geoscience methods of obtaining geographic information by field observation can no longer meet the needs of the current social development. Since the 1980s, with the advancement of spectral imaging technology, a large number of satellites and unmanned aerial vehicles equipped with panchromatic, multispectral, or hyperspectral sensors have been developed and launched all around the world. Remote sensing has become a popular modern method by processing information obtained by such equipment.
