Description

technical field

[0001] The present invention relates to the application technology of information resources, in particular to the application technology of using information obtained by remote sensing technology to provide auxiliary information for change detection applications such as changes in land resources, forestry resource investigations, and changes in agricultural land. Background technique

[0002] Change detection is to observe the state of the target or phenomenon in different periods, and quantitatively analyze and determine the characteristics and process of the change of the target or phenomenon. It involves the type, distribution and amount of change, that is, it is necessary to determine the ground type, boundary and change trend before and after the change.

[0003] In the past 20 years, many scholars have carried out research work on the dynamic monitoring method of land use / cover change based on satellite remote sensing. At present, the methods that are ...
