Research on DLG Graphics Coordinates Transformation

By means of the program based on the pixel coordinate information AutoCAD DLG graphics were extracted, transformation, update, the DLG graphics coordinate was transformed. DLG graphics coordinates transformation would solve the problems that often encountered in daily work gathered DLG data coordinate system is dif erent from the actual requirement of the dii culties, especially for conversion to solve everyday small batch DLG graphics coordinate system, low cost, convenient use.
