| Abstract: | The main purpose to develop a Map Graphic Workstation on the widely used micro-computer is that by it the whole processing of map data from capturing, managing, editing, updating to graphic outputting can be realized. Map Digitization System (MDS) is the software system to deal with the initial and also the most important processing. In this paper, the authors introduce a MDS on a micro-computer based Map Orphic Workstation that has been qualitified for the producation of digital map. Since the system is designed totally independently and in the general frame of the Map Graphic Workstation, the capturing and managing and other processings for map data are in an integral manner, in which the producation of digital map can be fulfilled conveniently. At the same time, the system is flexible for function extension and widely applicable to the data from different sources and with different information characterisitcs (e. g. , the processing of Chinese characters on map). |
