Rapid population growth vs spatial growth

South Africa continues to experience rapid urbanization with 53.7 percent of the population living in urban areas in 1996 rising to 54.4 percent in 2001 and 67.7 percent in 2011.

It is therefore crucial to monitor urban growth spatially for sustainable development and environmental management. For this reason SANSA has developed methodologies to automatically extract human settlement data from satellite imagery.

Sentinel-2B for enhanced decision-making in agriculture and food security

The successful launch of Sentinel 2B on the 7th of March 2017 provides the users with great wealth of data required to monitor the environment and manage food security. Sentinel 2B is part of the sentinel 2 mission that carries an innovative wide-swath high-resolution multispectral imagery with 13 spectral bands perspectives of our land and vegetation.

Sentinel 2A was launched on 23 June 2015 and has been contributing to a number of national, regional and international initiatives on agriculture and environmental management.
