Research Review of Investigation on Land Resources By Remote Sensing Technique

Land resources investigation is a behavior that uses some scientific methods and tools to identify a range of land resources, the quantity, quality, use, ownership status and spatial distribution. It is one of the basic problems in the land resources management. This paper reviewed the application of remote sensing technique in the progress of land resources investigation, and analyzes the application of remote sensing technique in the development process of foreign land resource investigation. The applications of the remote sensing technology of the land resource investigation mainly involve the land use dynamic monitoring, the land use inventory and mapping, the land resources investigation in our country. At last, it points out some problems on the application of remote sensing technique in our country.
