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. Group penetrating radar (GPR) is a non-destructive geophysical method […]

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 […]

Second SpaceDataHighway satellite successfully launched

The EDRS-C satellite, the second node of the SpaceDataHighway network (also known as the European Data Relay System (EDRS)), has been successfully launched into geostationary orbit at 31° East. After testing, it will double transmission capacity of the system in order to serve two observation satellites simultaneously and provide redundant back-up for the SpaceDataHighway. This […]

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 […]

Mapping the global human footprint

The number of people flocking to cities in search of employment and better prospects is growing at an unprecedented rate. By 2050, the global population is estimated to reach nine billion, 70% of which will be living in urban areas. The World Settlement Footprint 2015 (WSF-2015) is the first map, using mass collections of radar […]
