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 [...]

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 [...]

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, [...]

The CGA presented their Introduction to Geographic Information Systems (GIS) short course from 3rd to 7th of June, which was attended by 8 delegates. This course is aimed at beginners to GIS and teaches the basic theoretical and practical functionality of GIS. Themes covered in this course include: An introductory overview of GIS in the context of geo-information [...]

The CGA expanded at the beginning of 2019, adding a number of new members of staff to our team. We would like to welcome Dr Tara Southey, Mr Adriaan Prins and Mr Christiaan Theron. Dr Tara Southey joined the CGA in April as Postdoctoral Researcher focusing on climate change in [...]

The CGA is proud to be one of the winners of the SAEOchallenge! It seems that the judges agreed that our earth observation technology to map and monitor water use of irrigated agriculture at national scale is highly innovative. We hope that this exposure will lead to the [...]

The CGA is excited to be hosting an Advanced GEOBIA workshop with guest trainer Keith Peterson, Product Manager eCognition Trimble Inc. Germany. Themes that will be covered include convolutional neural networks; customised algorithms; point cloud & vector analytics, machine learning algorithms; and template matching.
