Services provided include

Search for satellite image coverage for a client’s area of interest free of charge.
Acquisition of satellite imagery:

        e.g. Sentinel-2, ASTER, Landsat 7,
              Landsat-8, SPOT,
              QuickBird, Pleiades,
              WorldView, GeoEye-1,
          Kompsat, RadarSat.

High precision geometric correction of satellite imagery.
We can also provide pre-processed Landsat TM and Landsat 7 mosiacs for regional scale studies.
Image processing to obtain the optimum visual contrast and edge enhancement to sharpen structural features.
Preparation of 3 band false colour composites and pan-sharpening.
Alteration processing of Sentinel-2, Landsat and ASTER data using any available geological control.
Sentinel-2, Landsat data can be processed to identify haematitic and jarositic iron oxides and generalized clay alteration anomalies.
Specialized processing of ASTER or WorldView-3 SWIR data using proprietary techniques to determine a range of alteration minerals that can be used to characterized hydrothermal systems and identify high temperature alteration centres.

Alteration mineral assemblages that can be identified from ASTER include:

         Adularia, Albite, Alunite-pyrophyllite,
         Biotite, Carbonate, Chlorite, Dickite,
         Epidote, Iron oxide, Illite-smectite,
         K-feldspar, Kaolinite, Limonite,
   Sericite.

Processing of night-time ASTER thermal imagery for detection of silica and carbonate alteration.
Preparation of colour coded alteration intensity maps on an ASTER, Sentinel-2 or Landsat B/W image background.
Provision of alteration data in vector format for use within a Geographic Information System.
Provision of image files as Geotiffs in the client's required format (e.g. ArcGIS, MapInfo).
