LAND COVER CLASSIFICATION METHOD ORIENTED TO GEOGRAPHIC NATIONAL CONDITIONS INVESTIGATION
Developing the project of geographic national conditions investigation is in order to obtain land cover change information which is caused by natural and human social and economic activities,and serve the information for government,enterprise and public.Land cover is an important method to describe the geographic national conditions information,which can truly reflect the land surface material type and its natural attribute.It has been contained in the content system preliminary scheme as an important portion.In this paper,it discusses and analyzes on the method and key technology,with according to the land cover content that geographic national conditions watches on.Then it evaluates the applicability of automatic classification method using in land cover information extraction,and comprehensively analyzes various extraction methods” maximum effectiveness.Finally,it proposes a method that is based on high spatial resolution remote sensing imagery and can be used in engineering applications,which provides a reference method for geographic national conditions investigation.
