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 multispectral remote sensing to determine fractional absorbed photosynthetically active radiation (fAPAR) in sugarcane. Crop growth models regularly use fAPAR as [...]

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 researchers in better understanding fires and fire-management teams in fighting the fires and making important decisions. One such model is [...]

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 and management. The generation of temperature surfaces usually involves interpolating temperature measurements taken at weather stations.  Although the weather stations [...]

Zani Mouton – GIS Scripter & Data Capturer

Biography Zani has always had an affinity for science, which, paired with her passion for computer science and geography led her to pursue a BSc degree in Geoinformatics at Stellenbosch University. Her particular interest in the applications of machine learning in remote sensing guided her research interest as she completed her [...]

Getting ahead of Salinization – article in Fresh Quarterly

The drought in South Africa in recent years has forced farmers to change their watering habits and use water more efficiently, resulting in crops being irrigated less frequently. This can lead to the accumulation of salts in soils, which can have a detrimental effect on production. In the article Getting Ahead Of Salinization, [...]
