| Abstract: | Digital geographical base map it provides the basic geographic elements for compiling various thematic maps for the geological departments. Taking Caofeidian Binhai region of Bohai Rim as an example, this paper completes the 1: 50000 digital geographical base map with the specification of geographical base map by GIS software. At last there is some suggestion for how to make 1: 50000 digital geographical base map work better in geological environments investigation. |
