Some of Our Products
5 m Stellenbosch University Digital Elevation Model (SUDEM)
The Stellenbosch University Digital Elevation Model (SUDEM) is a 5 m resolution digital elevation model (DEM) – a database of height above mean sea level records – representing the earth’s surface. The 5 m SUDEM, branded as SUDEM5, is currently the highest resolution DEM covering South Africa. It was interpolated from large scale (1:10 000 and 1:50 000) contours and spot height data, producing the so-called “Level 1 product”.
GeoSmart is responsible for the distribution of SUDEM5 and oversees its continual improvement. We have also used SUDEM5 in several products, including the Flood Hazard Index and the DEMSA2.

Contours
Contours are essential for many applications, including construction planning, hydrological modelling and environmental management. Geosmart Space provides contour data with 50cm vertical interval spacing for anywhere in South Africa. Other intervals (e.g. 1m, 2m, 5m) can also be provided. The contours can be converted to various formats, including those compatible with engineering software such as CAD and ModelBuilder.
