对原先的一个代码earth solution的源代码进行的升级，增加了三维地球放大，shp文件加载，纹理贴图定位。-A code for the original source code of earth solution upgrade adds 3D Earth zoom, shp file is loaded, texture positioning.

采用OpenGL技术，三维绘制Shp文件,其中包括解析Shp数据的Cpp文件。-Rending shp file in OpenGL，It will be useful for those major in GIS

用ARCGIS engine进行CAD矢量数据转换为SHP数据，并且通过等高线数据建立三维TIN(可以检查等高线的错误)-CAD vector data conversion performed by ARCGIS engine for the SHP data, and create three-dimensional contour data by TIN (you can check the contours of error)
