Abstract: The GPS-RTK technique,which is used to control the surveying in mountainous area and the layout method,data processing and accurate evaluation of large-scale digital mapping,are described. With this theory,engineering practice,precision analysis and verification are carried out.  The useful conclusions and suggestions are put forward,which will provide guidance and reference for engineering practice in the future.

Key words: GPS-RTK, the large scale digital mapping, control survey
