The Design of Cartographic Data Organization Model Based on the Availability Improvement of GIS Map Vectorization Achievements
In order to solve the shortcomings and defects of traditional cartographic data organization methods,a visualization expression method for map vectorization results based on Geographic Information System(GIS)is proposed.Based on the ArcGIS platform,the method uses the ArcMap software to carry on the secondary development to realize the processing and the analysis function of the map vector layer and the attribute information.On this basis,combined with spatial data management technology and object-oriented analysis theory,a set of map symbol database,note database,symbol database is constructed which is suitable for the process of making thematic maps of geographical entities.And it realizes all kinds of thematic map online editing,modification and output display operations through the map browser on the Web-side.At last,this paper expounds the key technical problems of the visualization of map vectorization results based on GIS and its application in practical work from many aspects,in order to improve the efficiency of cartographic data organization,and promote its development to a higher level.
