Managing heritage resources in the digital age

The South African Heritage Resources Information System (SAHRIS) online content management system allows South Africans to play a role in the preservation and conservation of their heritage, and offers the South African Heritage Resources Agency (SAHRA) a way to effectively coordinate the management of heritage resources.  The South African Heritage Resources Agency (SAHRA) is the […]

Smart infrastructure: mapping underground utilities

Beneath roads lie complex networks of cables and pipes, but often the owners of these systems don’t know their precise nature or location. Emerging digital technologies could enable the creation of real-time 3D maps of buried utilities – reducing inefficiencies, costs and risks. In recent years, sectors such as communications and the media have been […]

Mapping rockfall sources and deposit areas

Rockfalls are one of the major threats to the viability and liveability in the Alps. To identify areas that are at high risk due to rockfalls, it is important to study historical events and develop spatial models that provide accurate maps of rockfall deposit areas. To study rockfalls it is necessary to validate the results […]

Sugar cane monitoring and analysis using remote sensing

There is a need for more reliable and useful information that can aid farmers and various interested and affected stakeholders in optimising their operations. This study employed remote sensing and GIS techniques to monitor sugar cane crop performance and harvesting on the east coast of South Africa. The South African agricultural industry makes a significant […]

Cloud-based monitoring of SA’s water resources

Water is a critical and scarce resource in southern Africa and is likely to become even more so as the regional impacts of global climate change become more evident. Being able to accurately and repeatedly monitor available water resources across the entire landscape is a key information requirement for successful water resource management. GeoTerraImage has […]

Optimising stope design and quality monitoring with laser scanning

The demand of copper is such that progressively lower grades of copper ore are being mined profitably. One way to do so is by reducing the overall volume of waste material extracted, ensuring the highest concentration of the metal by minimising external dilution. Laser scanning can play a crucial role in achieving this. From a […]

Addressing shortcomings of land tenure reform in customary land rights

Despite over two decades of intervention, land reform in South Africa is failing [1; 2]. The failure of land reform is attributed to an inappropriate logic of land reform [2], which we link to differences in how land is understood, giving rise to application of inappropriate theory for the context [3, 4]. For land reform […]

Analytical-physical modelling and interoperability propel BIM

The increasing adoption of BIM as the method of choice for conceptual and detailed architectural design has resulted in more elaborate and complex designs than ever before. With this complexity, there is a need for more effective and automated BIM to structural analysis interoperability. As BIM becomes pervasive in all types of engineering projects, structural […]

Using drones to map land ownership in Kenya

Mapping land boundaries is an important way to boost a country’s economic growth and development. It contributes towards better security of land ownership, allows land owners to get bank loans and helps governments to tax owners correctly. Unfortunately, in most African countries only about 30% of the land boundaries have been mapped. Mapping is done […]
