TerraClim – StoryMap

We progressing well with the TerraClim project, and major milestone in the efficiency and accuracy of interpolations.The regional interpolation analysis divided the Western Cape study area into smaller regions using the local terrain and climatic characteristics of that particular region. The regionalisation of temperature interpolation showed improved accuracy of spatial interpolations by up to 0.8ºC [...]

CITRII – Burgersford Citrus Orchards

This video is a flyover showing the results of a satellite image (WorldView-2 dated 15 March 2020) analysis of a citrus orchard draped over the Digital Elevation Model of South Africa at 2m resolution (DEMSA2). The analysis was carried out for agricultural research and innovation business CITRII. The automated analysis developed [...]

VIDEO #03 | THE TERRACLIM PROJECT | WHAT’S NEXT?

Wynland has released part three of Winetech's flagship project, TerraClim, being undertaken by the CGA. For many wine grape producers in South Africa, access to accurate and detailed climate and GIS data is limited. Terraclim is funded by Winetech and is an online spatial decision-support system specifically [...]

Dense Point Cloud of Vineyard

This is a dense point cloud of a vineyard created with drone imagery with 4 bands (green, red ,red edge and near infrared). The imagery is displayed in false colour using the green , red and red edge bands. The dense point cloud was created using Agisoft Metashape and can be exported as a digital [...]

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 [...]
