Electronic map for GPS navigation and its data format conversion research are more and more in depth. In this paper, I have analyzed several existing GPS navigation electronic map data format on the basis of seeing a great deal of relevant information both at home and abroad, elaborate the quality control of production of the GPS navigation electronic map, furthermore, I have programmed a data format procedure of the GPS navigation electronic map. The program have accomplished the conversion of the GPS navigation electronic map from some MapInfo “Tab” format to the “Shape” file of the ERIS. Finally, in this paper, I have summarized the task I have accomplished, analyzed the problem of this paper, and then, I have raised some aspects that I need to improve.
