We systematically expatiated the application of GARMIN GPS Map 60CSx in stream sediment survey of 1:50 000.The channels pointing mistakes caused by using topographic map and other problems such as pointing distortion and sampling random caused by human factors can be avoided.It improves the efficiency of field sampling.After completing field work,GPS track points can be converted to the file which MapGIS software can identify according to the required scale by using GPSMapGIS software.The converted file can be added to the designed base map by using MapGIS software,managers can easily know the progress in the field and accuracy of sampling through GPSMapGIS software.It plays a very good role in sampling quality monitoring.
