Abstract: A new concept based on map cache slicing, GPS positioning technology and mobile terminal was proposed to build synchronous updating field surveying system of geographic national condition data and fundamental geographic information data. The system can implement that the same feature only needs to be measured once to updating geographic national condition data and fundamental geographic information data in the field. Repeated field production can be avoided by the system. Therefore the updating cost of geographic national condition data and fundamental geographic information data will be reduced.

Key words: synchronized updating, survey, geographic national condition, updating at 1∶10000 scale, updating at 1∶50000 scale
