| Abstract: | Map symbol making is one of the key technologies in digital map and directly related to the effect of the map.According to the basic idea and basic principle of symbol design,the advantages and disadvantages of the main GIS software are analyzed.Taking the design of flood control and drought resistance symbol database as an example,the method and process of making 2D symbol such as point,line and plane and design techniques of some complex symbols are analyzed.And set up a set of relatively complete standard of flood control and drought resistance symbol database,which lays a foundation for the production of thematic map of against flood and drought. |
