Abstract
When GIS are constructed primarily for the inventory and analysis of geographic phenomena, the data requirements for map production are often not considered. Such systems are also used to produce cartographic products including maps and mapping datasets. However, existing mapping systems built on GIS databases fail to make high quality map, mainly because most systems can not allow one to interactively change individual cartographic graphic representations to protect geo-data from modifications. This paper presents an alternative approach that considers the map requirements from the outset, then defines the unique characteristics and requirements for geo-cartography data to support a GIS-based cartographic system, as well as the process models to create the maps. Any representation is free to be intervened, and will not change geo-data. The geo-cartography data closes the relation between the geographic data and the cartographic data, and performs the function of describing the GIS connection tables or expression rules in visualization mechanism, and the function of supporting and saving the mapping edit in the map-making method. The cartographic representation adopts the geo-cartography data having been edited, not the default cartographic symbols, thus carries out map-making based on GIS, and is easy to renew maps.
