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.
