APPLICATION OF MAPGIS IN GEOCHEMICAL SURVEY: A case study of soil geochemical survey in Luoguhe reconnaissance area

In the soil geochemical survey of Luoguhe reconnaissance area in northern Daxinganling, Heilongjiang Province, the MAPGIS software of geographic information system (GIS) is applied, combined with global positioning system (GPS), to process the geochemical data and draw maps. The method is quick, accurate, and easy to operate. Being coincided with topographic and geologic maps, the anomaly map by this method is a help to the explanation and inference for anomaly and a guide to the exploration.
