And it is a realistic system which can imitative the geography space and a powerful tool which can process and analyze data. Shape file is the file format based on GIS data stored as files. It consists of three parts at least: .shp, .dbf, .shx, which are used to store space information, attribute information, and relationship respectively. The electronic map is free to zoom in and out of the vector map, which is achieved by geographical information system (GIS) and digital mapping technology, relying on the Internet and other digital media map. This paper is based on GIS by using Visual C++6.0. According to analyzing the shape file format, the map is displayed; the function is achieved such as roaming and zooming in and out.
