Abstract

Large scale map data base for multipurpose uses is designed and mapping program package is developed for map data processing system.
Relational data base model is applied to forming map data base. The map data base consists of data of graphic features and those of cartographic symbols. The geographic features is described by position and shape of terrain, building, boundary etc., as well as attribute data of them. This sort of separated data handling makes the data base flexible for its aplications in different uses.
Mapping program package is used for providing output data for graphic representation.
