Discussion on the Method for Extracting Regional Geochemical Anomaly Based on MAPGIS Digital Elevation Model
This paper deals with the extraction method based on MAPGIS digital elevation model, which needs not complex preprocessing before delineating anomalies and takes no account of geological background, geochemical landscape, research extent and profession of researchers. This method is characterized by strong adaptability, suppleness and speediness, and can objectively reflect regional mineralization features and spatial changes of geochemical elements, thus having great significance in regional geochemical study and prospecting for ore resources.
