Urban Energy Modelling - Semantic 3D City Data as Virtual and Augmented Reality

The visualisation of results from urban energy modelling and simulation is a crucial part of energy research as it is the main communication tool among scientists, engineers and decision-makers. Energy modelling and simulation results are directly linked to spatial objects, and 3D therefore becomes a necessity. The multiple interactive 3D visualisation environments that exist are mainly targeted as 3D viewers for use on desktop machines and lack immersive components that enable users to truly immerse themselves, explore and interact with the real environment onsite. In this study, the team focused on a holistic approach that implements a seamless transition from... (read more)

Dense Image Matching for Easy 3D Modelling

New Threat and Opportunity for Professional Surveyors
Normally when something is too good to be true, it is not true. But in the case of dense image matching (DIM), professional surveyors should look twice – because their clients, and certainly those in the construction, infrastructure and 3D city mapping markets, certainly will. 'GIM International' asked John Taylor, who is responsible at Bentley Systems for reality modelling in Asia Pacific and in the global defence market, for his insights into DIM. Dense image matching (DIM) did not arrive like a bolt from the blue. It has been around in the photogrammetric world for the past two decades but, through further... (read more)

The Expanding Field of 3D City Model Applications

The application space of 3D city models has expanded hand in hand with technical advancements. In addition to the ‘traditional’ use cases in urban planning and zoning, 3D city models are expected to facilitate energy analysis, detailed architectural visualisation, interactive and immersive applications development, and participatory GIS. All this places challenging requirements on 3D city model platforms. The discussion about 3D city models is further complicated by the amount of different platforms used for 3D city model applications. In addition to the professional GIS/CAD tools, 3D city models are used on game engines and various web-based 3D viewers, such as... (read more)

CloudCities adds IFC Support to its 3D City Models

CloudCities, formerly known as SmarterBetterCities, has announced a new upgrade to its platform to support the IFC (industry foundation classes) file format for BIM. This news follows the company’s announcement last October that it had integrated VUEWorks asset management products into its 3D city model service. That partnership enabled the easy integration of asset data, BIM, CAD, and GIS information with 3D reality data such as 3D meshes. With the added IFC support, the company says, working with BIM in the cloud is simplified further. The import workflow now offers user-friendly grouping options. CloudCities has also added an attribute editor,... (read more)

3D GIS in China

Chongqing Survey Institute Realised What Many Still Dream Of
Since 1998, the Chongqing Survey Institute (CSI) has been managing the 3D geoinformation database, including terrain, buildings, underground pipelines, geology and underground buildings, of the Chinese megapolis of 30 million people. For the commercial market, CSI’s 3D Mobile group focuses on combining the indoor and outdoor environment with e-commerce systems. Meanwhile, its BIM and GIS Integration group concentrates on three fields: geological survey, construction sector and municipal administration. Chongqing is a city of unique topographical and landscape features. It is built on mountains and partially surrounded by the Yangtze and Jialing rivers, making mapping the city a big challenge for...

Bluesky and Skyline Create Dynamic 3D Building and City Models

Aerial mapping company Bluesky is working with SkylineGlobe UK on a project to provide high-accuracy, photorealistic 3D city models that will be available as off-the-shelf datasets and via an internet streaming service. The new, dynamic 3D models will provide a visualization and analytical platform for smart city projects, transport and infrastructure planning, risk assessment and mitigation, development planning and environmental work. To create these unique 3D digital twins, Bluesky and Skyline will integrate leading-edge technologies. To capture the city imagery, Bluesky has deployed its hybrid oblique imaging and Lidar airborne sensor. Skyline is then processing and publishing the data into... (read more)

Bluesky 3D Models Improve 5G and Smart City Network Planning

3D digital models derived from high-resolution aerial photography are helping network operators plan the rollout of services including WISP (Fixed Wireless Access), 5G and Smart City applications. The work by Leeds based Wireless Coverage uses Digital Terrain and Surface (DTM / DSM) models. Derived from Bluesky’s aerial photography, the models are used within Wireless Coverage’s WISDM software which uses GPU Acceleration technology to create dynamic coverage maps. These maps are already being used to help operators plan network infrastructure, undertake property level look-ups and conduct marketing campaigns. “Recent jumps in wireless technology allow huge uplifts in speed of data access...
