Geoscience applications of QGIS: a bold new world in mineral exploration
summary
History of field mapping to modern workflows with QGIS shows MapInfo replacement, processing of airborne magnetic grids with a spatial Gaussian gradient/Novac magnitude filter via the map box 3 plugin, direct import of GPS-tagged smartphone and drone photos, Google imagery draped on SRTM with drillhole and surface sample plotting, and published QLR files from Geological Survey WA. A concrete missing piece is a drill hole and cross-section plugin that links 3D subsurface visualisation to mapped data.
