Abstract

Multi-scale handling and representation of terrain is one of the key hot topics in GIS. It can meet the demand of different users on the different scale geo-spatial data. Through multi-scale representation of terrain the non-scale GIS can be achieved and the users can acquire the info they care about easily by such GIS. This paper analyzes the concept of multi-scale reprensentation of terrain and the relative researches on multi-scale terrain representation. Also the construction of multi-scale terrain is discussed, and its application in terrain analysis is described.
