REGIONAL SCALE MAPPING WITH ASTER
PhotoSat offers a geological alteration mapping package produced using ASTER satellite photos. In areas of sparse vegetation, ASTER photos are used to map opal/chalcedony, total silica, kaolinite, jarosite, sericite, chlorite, calcite and many other minerals for epithermal gold and silver and porphyry copper exploration.
PROPERTY SCALE MAPPING WITH WV3
PhotoSat offers a geological alteration mapping package produced using WorldView-3 high resolution satellite photos, with about 64 times the resolution of ASTER alteration mapping. In areas of sparse vegetation, 16 band WorldView-3 photos are used to map opal/chalcedony, kaolinite, jarosite, sericite, chlorite, calcite and many other minerals for epithermal gold and silver and porphyry copper exploration.
