DESIGN AND IMPLEMENTATION OF DECISION-MAKING SUPPORT SYSTEM FOR THEMATIC MAP CARTOGRAPHY

Thematic map symbol is a basic component of thematic map language and it plays an important role in expressing the thematic content. However, the extensity of users leads to the diversity and complexity of the thematic symbols and expression methods, and most of the thematic maps do not have a fixed format and norms like topographic map. At the same time, we can not require all the users to be very familiar with GIS Mapping knowledge. Thus, it is needed that the system can provide a decision-making support system which can produce high-quality maps for the general GIS users while the geographical information is visualized. Moreover, the decision support system must be built on the basis of map design software. That is to say, there should be a decision support system for thematic map cartographic in GIS. It can combine cartographic knowledge with the map design module and mapping module together. This paper first discusses the necessary and results of the usage of decision-making support system for the thematic mapping application. And then it is followed by a thematic analyse the decision problems in the process of the thematic mapping. The system uses the different decision-making model or different reasoning method according to different issues. In the final, it focuses on the structure and function of decision support system for thematic mapping which is designed and programmed based on JBuilder2005 introduced and SQLServer2000. * ping2puti@163.com; phone: 027-87152816
