| Abstract: | In this paper, a method of graphic overlay analysis from the grid data is intro-duced. Four technical processes are proposed: A way of chain topology for converting the vector data into grid data. A specific encoding for data compression of grid mode and and its effective storage. Based on the fuzzy theoory a mathematical model of multielement comprehensiveanalysis is established. A border following program using in the grid merging after attribute data typesoverlay analysis. Finally, an application of land-use evaluation for buji (a town in Shen-zhen city)town planning is shown to examine the proposal model of grid data graphic overlay bythe author. |
