A shapefile stores non\|topological geometry and attribute information for the spatial features in a data set, and its inner structure is complex. The method reading geometry and attribute information of shapefile is shown. It sets up a temporary data source, and reads attribute table dynamically. The interface frame of transforming Shapefile to another data structure is designed, and the method of reading Shapefile with C++ is given. The method is testified with the GIS(Geography Information System) manage system of S city pudong construction office, its veracity reachs 98%.
