Due to the region’s proneness to occasional wildfires, the Geomatics Division at the University of Cape Town, South Africa, has conducted research and project work around the theme of 3D reconstruct...

How 3D Modelling Supports Game-changing Urban Development

How 3D Modelling Supports Game-changing Urban Development

Accurate digital representations of cities are game changers in urban development. By enabling virtual modelling and smart simulations, they allow decision-makers to explore, test and assess the measu...

Automated Mobile System for Mapping Mine Shafts

Automated Mobile System for Mapping Mine Shafts

Read about this automated mobile laser scanning system developed for mining. It facilitates fast and precise measurements to produce a 3D model of the mine shaft for further analysis. Mine shafts are ...

Digital Twins: A Comprehensive Solution or Hopeful Vision?

Digital Twins: A Comprehensive Solution or Hopeful Vision?

The concept of the digital twin has been gaining significant momentum in the geospatial domain since 2016. Although there is some consensus on the basic features of a digital twin, some critical refle...

SDG 11 as a ‘Glocal’ Framework

SDG 11 as a ‘Glocal’ Framework

In urban planning, there is a case for stronger connections between global and local (‘glocal’) issues, strategies and actions. How can the Sustainable Development Goals (SDGs) help local governme...

The Surveyor’s Need to Embrace Data Management

Read this interview with Topcon's Ulrich Hermanski for his views on the current status of the surveying profession, the key advances and the future role of surveyors. Since graduating in Geomatics Eng...

The Pitfalls of Working with Lidar

The Pitfalls of Working with Lidar

The arrival of unmanned aerial vehicles (UAVs or ‘drones’) has democratized the Lidar market forever. Everyday projects can be flown easier and faster, and sensors are getting lighter, more accura...

Visualizing Point Clouds in Game Engines

Visualizing Point Clouds in Game Engines

How can the dense point clouds that originate from 3D mapping be turned into useful game engine scenes? This article considers issues including point classification and segmentation, geometric accurac...
