| Abstract: | Space database of 1: 200 000 Comprehensive Hydrograpric Geological Map of Nong' an is an example of GIS in application. The whole process of establishing the space database using GIS was introduced. Main operational steps and methods and problems merit consideration in the establishing process are discussed. Ensuring graphical precision mathematically, rationalizing the topological structure and correcting attribute link in data capture and in the establishment of space database with attribute are emphatically discussed. |
