CHEN Jie①,DENG Min①,XU Feng②,XU Zhen①(①Department of Surveying and Geo-informatics,Central South University,Changsha 410083,China;②Resource & Environment Science College of Hunan Normal University,Changsha 410081,China)  
Measurement of geospatial information is the key factor for evaluating cartographic quality and generalization algorithm,and transferring to geospatial information.To develop a set of new measurements for geospatial information,this paper makes a critical examination of the existing approaches for geospatial information measurement.And then,a reclassification of contents of geospatial information is made from the consideration of geometric,thematic,topological and thematic topology.The corresponding measurements are further developed,including geometric information entropy,thematic information entropy,topological information entropy and thematic topological information entropy.It has been shown by an example that the proposed method in this paper could effectively measure the geospatial information.
