Description

This GeoDataPack of Nelson Mandela Bay local municipality, which includes the city of Gqeberha, combines various DEMSA2 derivatives and is ideal for detailed spatial planning and hydrological modelling.

GeoSmart is currently creating GeoDataPacks for all municipal areas in South Africa.

GeoDataPacks are collections of geospatial datasets tailored for improving decision-making and solving geographical problems.  GeoSmart’s GeoDataPacks were collated from various sources and formatted so that they can be used in various software packages, including Google Earth, QGIS, and ArcGIS.  The datasets can also be viewed as digital maps.
