GeoDataPacks

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.

GeoSmart is currently creating GeoDataPacks for municipal areas in South Africa. Below are some examples of the datasets that are included in each GeoDataPack.
