Abstract:

Regional geological survey has important significance in basic and public geological work of national economic construction in all areas. PRB digital mapping technique has good effect in regional geological survey of Huangshabao sheet with the scale of 1∶50000. In this paper, PRB proeedure of digital mapping techniques from field to indoor and the final production have been introduced. It proves that digital teehniques in region geological survey are high-speed and precise.
