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)

Satellite Imagery: An Aerial Alternative

Remote sensing projects often begin with the question: 'Should I use aerial imagery or satellite imagery?' During long-term projects, this question may arise again, particularly when unforeseen circumstances change the ability to collect data, the reliability of the data or the scope of the work. Budgets, technology and government restrictions constantly change, making it critical to choose the right data inputs. There are a number of key parameters that must be taken into account when beginning any remote sensing project. These include the size and accessibility of the area of interest, the timeliness of the data, whether the data can... (read more)

Land Reform, Data Revolution

How a National Land Register Has a Positive Impact on Life in Rwanda
Thierry Ngoga, Head of Support to State Capability at AGRA, considers the valuable lessons offered by Rwanda’s recent land governance reforms. In Africa, land reform can be a highly complex and political process. As a result, governments are often reluctant to engage in land reform programmes, preferring instead to maintain informality and flexibility in this area. But for those countries that do change the way land is held and administered, the benefits can be significant. Here, Thierry Ngoga, Head of Support to State Capability at AGRA, considers the valuable lessons offered by Rwanda’s recent land governance reforms. Land reform, properly... (read more)

Scanning 100 Dutch Railway Stations

Geomaat recently performed extensive 3D laser scanning and 3D modelling for the Dutch railway organization, ProRail. ProRail is the organization that takes care of the entire railway network in the Netherlands, from construction to maintenance. It is essential that the data in the ‘Basic Management Map’ (Basisbeheerkaart) which is used to manage the network, is up to date at all times. ProRail works with various suppliers to map the railway network. One of those suppliers is Geomaat, which recently supported Arcadis on a ProRail project in order to add its own experience in 3D laser scanning and 3D modelling to Arcadis’ extensive railway-related...

How Rapid Scanning Provides Support During a Global Health Crisis

Geospatial technology can play an important role in the expansion of hospital capacity in response to the coronavirus pandemic. In this feature, David Fowkes, sales director at 3D mapping and monitoring specialist GeoSLAM, explains how the rapid surveying capabilities of SLAM technology can enable health officials across the globe to quickly and safely assess potential hospital buildings. Around the world we have seen unprecedented efforts to increase capacity in stretched health systems as a result of the spread of coronavirus. In Wuhan, China, the epicentre for the virus, the 269,000 sq ft, thousand-bed Huoshenshan Hospital, was built from scratch in... (read more)

Remotely Sensed Data for Efficient Data Collection

Taking a Closer Look at Impact from Hundreds of Kilometers above the Earth
When it comes to impact evaluations, remotely sensed data can increase their timeliness, accuracy and relevance for decision-makers. 3ie and New Light Technologies are enhancing the use of geospatial analysis in IEs. Impact evaluations (IEs) have been evolving to fill a critical gap in evidence about the effectiveness of international development programmes and interventions. Because of their ability to determine intervention effectiveness (and cost-effectiveness), the demand for and production of IEs has grown substantially in recent decades. Rigorous evaluation of development interventions and their outcomes has been a perennial challenge across multiple sectors and disciplines. Remotely sensed data allows to... (read more)
