COMPUTER-AIDED DESIGN OF MAP COLOR
摘    要:The design of map color is an important part in map design, especially for thematic mapping, importance is no less than that of map content itself.Tranditional method in map color design is to make several designing variants and then make a comparison among them and finally choose one of them.This method is time-consuming and rather expensive.With the development of interactive computer graphics,now the design of map color can be completed by means of computer processing. During this procedure, cartographer's knowledge in map design, rich color in computer and the powerful functions of graphic processing of computer can be combined together. Three main problems about comprter-aided design of map color are discussed in this paper: The first is to create a database which forms the basis of color producing; the second is to create a cartographic database for organized raster data; the third is to design an interactive svstem for the design of map color with the support of the two databases mentioned above.
