Staying ahead of Hurricane Dorian with geo-information

As Hurricane Dorian moves north in the Atlantic Ocean, brushing the United States’ Southeast coast with strong waves, winds, and rain, the United States Geological Survey (USGS) is providing comprehensive scientific capabilities and information that decision makers, emergency responders and communities can use to help them prepare, cope and recover from the storm. The USGS’s […]

Understanding the applications and benefits of ground penetrating radar

The ground penetrating radar market in South Africa is gaining popularity. This paper will look at what it is, explore its complementing technologies, where it is used, some examples and case studies from around the world and what is happening in this market in South Africa.

Surveying remote areas with precision for bird conservation effort

How a new approach to precise positioning is helping solve a century-old problem on an isolated island. John Houston is not a surveyor. He’d be the first to tell you that. He’s not a keen traveller, either. So what was he doing on a speck of an island in the South Atlantic Ocean, knee deep […]

Machine learning for road width capture from aerial photography

In this proof of concept, the use of feature extraction through machine learning using convolutional neural networks to classify aerial photography pixels as either road or non-road, and produce a basis for a polygon feature representing the road surface (and therefore road width) is demonstrated. Aurecon received a brief from a client to build a […]

Census geography: What constitutes the ideal output area for South Africa?

A specific designed output (spatial) layer to disseminate census data is aimed at enabling governmental departments, municipalities, various planners and researchers, with the smallest geographic areas that will be linked to census data to facilitate better and more detailed planning and decision-making processes. By not using the census operational layer, i.e. the Enumeration Areas (EAs), […]

A spatio-temporal approach to underground mine health and safety monitoring

Health and safety of employees in their work environment, particularly in underground mines which are deemed one of the most dangerous work places in the world, is of critical importance. This article highlights a prototype application that integrates legacy underground mine systems with a geographic information system (GIS) for the analysis of streaming digital sensor […]
