Abstract GPS navigation is commonly used to locate each sampling points during regional geochemical sampling work. At present, however, the sampling locations should be recorded in GPS by manual input. This paper mainly deals with the conversion of point file in MapGis to navigation points of MapSource in the regional geochemical sampling arrangement map. This technique can undoubtedly improve the sampling efficiency and precision in field work.
