“…By using Geographic Information System (GIS) software, we independently developed 'Geological map automatic inspection and modification system', systematically checking the geological map data of all provinces (autonomous regions and municipalities), matching all abutting boundary areas of the maps and presenting a seamless, nationally consistent, digital geological map. On this basis, we established the database management system of The Regional Geology of China, and achieved automatic mapping based on MAPGIS (Fan et al, 2011;Ding et al, 2012a;Ma et al, 2015;Hu et al, 2018). Based on the DEM data, the three -dimensional geological map was also achieved .…”
