| Abstract: | Geographic feature object identifier （GFOID） is an important component of spatial information system. The related definition, property, types and generation methods of GFOID are analyzed and summarized. Thus, a geographic feature object identifier based on map subdivision and feature classification codes or GFOID-MSFCC, is put forward. Then the GFOID-MSFCC＇s features and functions are explored in details. Finally, the application of GFOID-MSFCC to the fundamental geographic information change-only update is also discussed. |

| Keywords: | geographic feature geographic feature object idemifier subdivision for topographic map classification and code of geographic feature change-only update |
