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...

Eye-bot Aerial Solutions Creates Highly Accurate 3D Vertical Monopole Models

ContextCapture Safely Collects More Data Faster to Build Precise Reality Meshes
In 2017, Eye-bot Aerial Solutions, a drone service company, completed a 3D reality model of cell tower antennas in Springdale, Pennsylvania. The project team at Eye-bot initiated the Springdale Monopole project to improve model fidelity, positional accuracy, and photo-realism by comprehensively modelling vertical monopole structures that feature transparent, complex cross-bracing. In the long term, Eye-bot strives to use the enhanced models to help create standardized 3D modelling workflows. The organization specializes in using unmanned aerial vehicle (UAV) photogrammetry to generate 3D models of cell towers. Based in Pittsburgh, Pennsylvania, Eye-bot has worked within several industries, including industrial manufacturing, oil and... (read more)

3D Repo Adds Geospatial Dimension to Digital Construction Week

The annual Digital Construction Week kicked off on Monday 16 October with a packed British Information Modelling event held at the Geovation hub in central London. The fourth in a series of bi-annual events organised by 3D Repo, speakers from Bryden Wood, Skanska, Flux, Ordnance Survey and Podaris took up a geospatial theme with delegates debating issues such as data access, integration and collaboration. Skanska’s Vaibhav Tyagi talked about its lead in the Innovate UK government backed project to provide integration between geospatial and BIM data. Elite Sher of Bryden Wood was then joined by 3D Repo’s Pavol Knapo to present their developments... (read more)

BIM Market to Reach US$18.8bn by 2024

The value of the global building information modelling (BIM) market has been projected to reach US$18.8 billion by 2024, up from a valuation of US$3.6 billion in 2016. The 'Global Building Information Modelling Market' report, published by Esticast research and consulting, found that emerging countries in Southeast Asia and Europe will be major drivers of this projected expansion, with rapid growth propelled by infrastructure development to support rapidly growing populations in nations such as India and China. The report divides the BIM market into application areas, defining commercial, residential, institutional, infrastructure and industrial segments. Geographically, the market is segmented into North America, Europe,... (read more)

Bringing in GIS (3)

Innovative GIS projects are exciting to the technologist who understands and clearly sees the benefits. More challenging is convincing budget-holders and broad business that the investment is worthwhile. This can be done using the simple but powerful benefits-modelling approach.<P> This article, the last in a series of three, represents the final piece in the jigsaw of a business-driven approach to justifying GIS projects. The first article demonstrated the merits of a top-down, business-led approach to effecting change, as opposed to a bottom-up, technology-driven solution. The second article  showed how to design an organisation and plan for success by establishing a... (read more)

Unique 3D Habitat Map of the Great Barrier Reef

International aquatic remote sensing company EOMAP recently showcased its unique contribution to the world's first 3D habitat map of the Great Barrier Reef (GBR) at the International Forum on Satellite-Derived Bathymetry (SDB Day 2019) in Australia. The mapping project, titled ‘3D live habitats for the full extent of the Great Barrier Reef’, will for the first time provide maps of the predicted coral types and underwater landscape for the more than 3,000 reefs within the 350,000 square kilometres of the GBR. EOMAP’s cutting-edge technology provides essential data for this revolutionary project, in which the University of Queensland (UQ), Great Barrier Reef Marine Park... (read more)

Precision Flood Models and Spatial Analysis of Flood Risk

This article explains how modelling is a vital tool in understanding flood risk and in mitigating the effects of flooding in Great Britain. Paul Drury explains how recent research undertaken by flood risk specialists at Ambiental has enabled the development of precision flood models and explores how data generated through flood modelling can provide some interesting insights into the spatial pattern of flood risk. Flood modelling depends on accurate topographic data. The resulting outputs, combined in a GIS with accurate spatial representations of our built environment, enable insurance companies, public authorities and the general public to understand flood risk and...

EarthSense Systems Computer Models Impact of Trees on Urban Air Pollution

Software developed by EarthSense Systems has been used to assess how trees impact on urban air quality on one of London’s most polluted streets. Called FluidAir, the state of the art solution uses Computational Fluid Dynamics (CFD) to simulate the flow and dispersion of pollutants within complex 3D surroundings, such as city streets. Scientists at EarthSense Systems, who specialise in air quality monitoring solutions, integrated road, building and tree data to create an accurate 3D model of the Marylebone area of London. Recorded pollution levels were combined with traffic flow data from the Department for Transport and meteorological information from... (read more)
