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 […]

Cape Town’s water usage map has residents seeing red

The latest weapon in Cape Town’s water saving arsenal is a map that exposes private meter readings to public scrutiny. The initiative has been launched as the city enters the third year of its worst drought on record. Unless residents can cut their daily water use to 50 litres per person, city authorities estimate that […]

Identifying revenue loss using GIS

Being able to connect meter usage with billing and service requests can help utilities identify the extent of their equipment problems. This article looks at zeroing in on clusters of dead meters using GIS software. Opelika Utilities in Alabama, US serves nearly 20 000 customers. Its mission is to determine the current and future water […]

Combining GNSS and sensor networks for construction efficiency

The construction industry faces a number of challenges. Performing under deadline pressure is just one example. More recently, the focus of attention is compliance with emission values. A geomatics approach could help. The European demolition industry, especially in Germany, must focus on compliance with strict regulations. In the last couple of years it has become […]

Spatial analysis to prioritise spatial investment of social infrastructure

This analysis formed part of a project for the Department of Rural Development and Land Reform where the core focus was on the development of differentiated provision standards for locating a range of social facility types. The ultimate aim is to improve access to, and the spatial distribution of, facilities in rural areas, and ensuring […]
