Abstract Through the research for the rules of storing entity data in the DXF, achieving that the direct operating of DXF file to complete maps conversion without the CAD support is achieved and the corresponding graphics conversion program has been compiled with specific projects. After test, with this program we can complete map conversion between National Coordinates, National Coordinate and Local Coordinate, Local Coordinates, and we have achieved integrated blocks conversion in the conversion process.
Key words ：
CAD map conversion
DXF file
blocks conversion
national datum modernization
coordinate transformation
