About

A home for South Africa's hydrogeological data

The repository aims to host South African datasets related to hydrology and geohydrology. In addition to the datasets, legacy and newly developed geohydrological software packages are also hosted, along with a growing set of in-browser apps that run directly in your web browser with nothing to install.

Although some resources are public, only registered users will have access to all resources due to copyright restrictions.
