Study of Geospatial Knowledge Map's Visualization Based on Users

Currently,the development of geospatial data from information management to knowledge service was considered as one of the hot research fields in geographic information science.Started with the study related to the theory about geospatial knowledge map and its visualization,aiming at current map' s application needs and development trend,geospatial knowledge's classification and visualization,geospatial knowledge map's characteristics and other contents were analyzed in this article.Then the process model and essential strategy which can turn geospatial information visualization to geospatial knowledge visualization was researched based on the relationship between users and geospatial knowledge visualization.
