CGA and SASRI remote sensing in sugarcane research published

Prof Adriaan van Niekerk and Jascha Muller of the Centre for Geographical Analysis (CGA), and Dr Abraham Singels of the South African Sugarcane Research Institute (SASRI), have published their collaborative research assessing the use of [...]

  • Figure 1 Predicted vs actual spread on the 25th of October 2018. The simulated perimeter is red, and the actual perimeter is light blue. Reference points used for the accuracy assessment are black dots with a white outline. The Sentinel-2 image, captured on 25 October 2018, is displayed as a Red, Green, Blue image where Red = Band 12, Green = Band 8A, and Blue = Band 4.

Assessing the ability of the Prometheus Fire Simulation Model to predict fire spread based on the 2018 George fire

By Lauren McCarthy Wildfires occur globally, destroying thousands of hectares of vegetation, affecting ecosystems, the environment, and humans. Fire spread models, based on fire behaviour algorithms, have been developed in different regions to aid [...]

Sentinel-3 land surface temperature for air temperature estimation

Air temperature varies across the Earth and as such it can be represented as temperature surface (map). Temperature surfaces provide critical information for applications  relating to climate change adaptation and agricultural planning [...]



Climate SDSS

Winetech has recently appointed the Centre for Geographical Analysis (CGA) to develop a prototype online spatial decision support system (SDSS) for the wine industry. The project is being carried out in close collaboration [...]
