Advanced Urban 3D Modelling and Visualization

A Generic Workflow for Automatic Building Detection and 3D Modelling
The automatic detection, data extraction, 3D modelling and visualization of buildings in urban areas using remote sensing data is an essential task in various applications such as cadastre, urban and rural planning, change detection, mapping, updating geographic information systems, monitoring, housing value and navigation. Even today, this task still remains challenging due to the inherent artefacts (e.g. shadows) in the remote sensing data used, as well as the differences in viewpoints, surrounding environment, complex shape and size of the buildings. This article outlines a generic workflow using modern technologies. Besides the recent developments in image processing, advances in computer vision... (read more)

Full Automation in Mobile Lidar Data Classification

An End-to-end Framework Using 3D CNN and SVM
A deep learning architecture called MMCN opens up the possibility for fully automated classification of highly dense 3D point cloud data acquired from a mobile Lidar system. This offers interesting opportunities in applications such as high-density maps, autonomous navigation and highway monitoring. Classification of highly dense 3D point cloud data acquired from a mobile Lidar system (MLS) is essential in applications like creating high-density maps, autonomous navigation and highway monitoring. MLS data classification algorithms available in the current literature use several parameters or thresholds. The right selection of these parameters is critical for the success of these algorithms under different... (read more)

Explosion in Beirut Seen from Space

On 4 August 2020, there was a huge explosion in the port of Beirut. The scale of the accident was so large that the damage could be seen from the satellite orbit around Earth. The European Sentinel satellites, operating under the Copernicus programme, took pictures illustrating the enormity of the damage. Just after the explosion in the port warehouse, pictures began to circulate showing the moment of the explosion. The scale of damage in zone was so big that it could even be seen from several hundred kilometres above sea level, for example on images taken by the European Sentinel-2 satellite.... (read more)
