一种基于Map GIS区明码文件的快速分类赋色方法

摘要

通过分析MapGIS区明码文件结构，提出一种利用Excel的VLOOKUP函数，批量修改明码文件区颜色参数，并结合VBA编程语言快速实现区块分类赋色的方法。文中方法能够较好地解决M apGIS拓扑重建随机赋色的问题，在一定程度上既简化了图件分类符号化的步骤，又保证了图形数据的正确性。%By analyzing the file structure of MapGIS area codes ,it proposes a method of fast implementation to color block with classification ,with Excel’s VLOOKUP function to batch modifying color parameters in area code files combined with VBA programming language .This method can effectively solve the problem of MapGIS topology reconstruction with random color .To a certain extent ,it not only simplifies the step of map classification symbolization ,but also ensures the correctness of the graphic data .
