SAR project for southern Africa underway

Scantherma has started collating and mosaicing SAR imagery for southern Africa. The project was initiated and financed by several junior mining companies and stakeholders to help build a base for further geological mapping in nations such as Botswana, Zimbabwe, Mozambique, Tanzania and Zambia.

The project will primarily use imagery acquired by the JERS-1, RADARSAT and PALSAR satellite sensors with spatial resolutions of between 10 and 50 meters.

The total mosaic is expected to be over 30Tb, so no doubt a few compression techniques will be required to make the data use-able in mapping software such as ArcGIS and MapInfo.

Geologists can expect to identify the following from the final product:

  • Regolith. Extent, and relevance towards regional geology and geomorphology
  • Identification of faults and lineaments
  • Analysis of folds and curvilinear features. Particularly important in low-lying terrain where surface features are often too subtle for immediate identification
  • Paleo-channel mapping in arid regions. This is particularly important to diamond and uranium exploration.
