The invention discloses a rapid map making system based on GIS (Geographic Information System) data. The rapid map making system based on the GIS data is used for converting the GIS data into map making data in a high-precision map data format for map making publication, and completing intelligent pre-processing of the map making data in the data conversion process by fully utilizing rich semantic information in the GIS data and map making rules predefined in the map making system. The rapid map making system based on the GIS data comprises an original GIS data reading module, a symbol library establishing module, a graphical design repository module, an element conflict process repository module, a map making rule providing module, a map data generating module and a map file input and output module. According to the invention, the GIS data is converted into the map making data, therefore, the pre-processing operation of a large amount of the map making data can be completed before the map is edited, the map making period of a digital map is shortened, and the map making efficiency and quality based on GIS data are improved.
