Use of remote sensing in the second national land investigation in China

摘要

Land is an essential resource for economic and social development. Land resources investigation is important yet quite challenging. Geospatial technologies such as remote sensing (RS), global positioning system (GPS), and geographic information systems (GIS) have been utilized to support the second national land resources survey initiated by the Chinese central government since 2007. In this paper, we analyze the feasibility of using the remote sensing technology to support the second land resources survey and discuss the method of processing and interpreting remotely sensed data. We conclude that the remote sensing technology is critical to the completion of the second national land resources survey.
