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)

3D Smart Digital Model Shows Calamities in a City with One-look Overview

A unique 3D smart digital model has been developed to combine the different streams of data from cities on one common platform, and is the result of the ITEA project PS-CRIMSON, a collaboration of six academic and industry partners from the Netherlands and Canada. With this platform, public safety and disaster management can be improved, as pilot projects in Eindhoven and Vancouver have shown. Researchers from Eindhoven University of Technology developed AI image technology that can detect the location of incidents from an image and retrack the walking routes of people using multiple cameras. Today, PS-CRIMSON was awarded with the ITEA Award... (read more)

Integrating Lidar and Photogrammetry Mapping Technology

A system that combines cameras with Lidar is generally called a mapper or mapping system, but is also known as a hybrid system. The airborne market for area-wide 3D data acquisition is experiencing a noticeable trend towards a fusion of Lidar and photogrammetric mapping. Here, the latest trends and technologies are summarized in three articles that give a good overview of the current state-of-the-art in aerial mapping. When Photogrammetry Meets Lidar: Towards the Airborne Hybrid Era The airborne market for area-wide 3D data acquisition is experiencing a noticeable trend towards a hybrid mapping concept. In the near future, most airborne data collection... (read more)

Thermal Mapping Helps Target UK Government Green Home Grants

Using a high-tech thermal imaging camera to measure heat loss from roofs, aerial mapping company Bluesky International is helping to identify poorly insulated homes and other public buildings. The property level heat loss maps provide an accurate and up-to-date picture that could be used to pinpoint homes eligible for financial support such as the UK Government’s Green Homes Grants. The UK Government recently announced a package of grants worth a total £2 billion for energy-efficient home improvements, including installing insulation, double glazing and replacing old boilers. The remaining £1 billion of the package will be spent making public buildings including... (read more)

4 Earth Intelligence Launches Countrywide Satellite Intelligence Data

Earth observation company 4 Earth Intelligence (4EI) has launched a suite of data layers providing insight into a country’s wealth, demographics and transportation links. Derived from satellite imagery and other reputable resources, including the World Bank, OpenStreetMap, census records and historical archives, the Country Intelligence data suite has been created to support economic analysis, policymaking and SMART Sustainable Development Goals (SDGs) reporting. “Satellite imagery records what is happening on the planet rather than what is being reported and so is the perfect resource, when combined with multiple, validated data sources, to provide off-the-shelf resources for countrywide intelligence on economic and...

Japanese City Performs Field Surveys Using GIS on iPads

The City of Tamba in Hyogo prefecture, Japan, performs field survey work using a mobile GIS application designed for Apple iPad tablet computers. The application, called Mobile Matilda, has been developed by an Osaka-based GIS solution specialist, Tsukasa Consulting, using the TatukGIS Developer Kernel 11 (for Delphi edition) with the Embarcadero FireMonkey framework. The mobile application compliments desktop and web-based versions of the Matilda software that are enabled with more features. Unlike web applications, Mobile Matilda can operate in a local (off-line) environment because map layers and data are read from the iPad memory. Users can update records in the... (read more)
