Geological Mapping at SGS
Maps are compiled using field observations, aerial
photographs, remote sensing and thematic mapper
images, topographic maps at various scales, and
laboratory analyses of samples collected in the field.
Geological maps and the accompanying explanatory
notes are published by the SGS publication unit.
Technical expertise, advice and services in all
aspects of mapping of sedimentary rocks can
be provided by SGS. This is available to the
governmental and private sectors, as well as to
those engaged in academic research.
The department produces geosciences maps at 1:250,000 scale with explanatory notes.
