Abstract

The invention discloses a template based one-button type thematic map automatic forming method and system, belonging to the field of computer mapping and relating to the computer automated mapping and mapping synthesized technique. According to the method, a basic data support module comprises a spatial database, a model library and a thematic map mapping template library; the specific mapping steps comprises the follows: establishing the spatial database, selecting content information of the thematic map, establishing the template library, selecting a thematic data representing way, establishing the template library, configuring display information of mapping elements, generating a thematic map configuration XML (Extensive Markup Language) text and analyzing the thematic map configuration XML text, and visually outputting the thematic map configuration XML text. According to the technical scheme provided by the invention, the thematic mapping efficiency and the mapping accuracy can be improved, the mapping automation and intelligence level can be improved, the thematic map making process can be speeded up, and the manpower, the material resources and the financial resources can be economized.

Description

technical field [0001] The invention belongs to the field of computer graphics, and relates to Computer-Aided Cartography (CAC for short) and Cartographic Generalization technology (Cartographic Generalization), in particular to a template-based one-button thematic map automatic mapping method. Background technique [0002] Maps are gradually developed by human beings in the process of understanding the earth, and they are tools for understanding the world created by human beings in social practice. Thematic map (Thematic Map), as an important branch of map, is a map that focuses on one or several elements in natural or social phenomena, that is, a map that concentrates on a certain theme, such as mineral resource maps, ethnic maps, and cultural maps. Wait. The thematic map drawing process is essentially the process of processing and symbolizing spatial location data (basemap elements) and attribute data (thematic elements). Thematic maps can better reflect the spatial loc...
