Bluesky International to develop new Triangular Irregular Network simplification tool for collecting data from digital models of towns and cities

NEWS: Leading UK aerial survey company collaborates on major geographic data project

Geographic data specialist will collaborate with University of Leicester experts, funded by SPRINT

Bluesky International, the leading aerial survey company in the UK, has signed up to the national SPRINT business support programme, to collaborate on a major geographic data project with SPRINT partner, the University of Leicester.

The project will improve the processing time, reduce data storage costs and provide energy savings for organisations such as insurers, real estate companies and local administrations collecting data from digital models of the urban environment. It will do this by focusing on developing a triangulated irregular network (TIN) or mesh simplification tool, based on adaptive AI-guided mesh coarsening methods – an established technique used to accelerate the numerical simulation of physical phenomena.

Bluesky will collaborate with the Applied Mathematics Group at the University of Leicester to use artificial intelligence and machine learning techniques to reduce the complexity of existing mesh models intelligently and adaptively, without loss of detail, accuracy or integrity. This will make the models easier to use and disseminate by reducing the data volume.

This project will support Bluesky’s MetroVista mesh model products. These are fully rendered photo-realistic 3D models of UK towns and cities, in unprecedented detail. As they are geometrically and geographically accurate, they can be used for in-depth analysis, measurements, modelling and visualisation, for example.

This project with the University of Leicester will be funded by the £7 million SPRINT (SPace Research and Innovation Network for Technology) programme. The project follows a previous collaboration with the University of Leicester on a major data collection project to collect and analyse key urban environment data to provide business intelligence for the UK insurance sector.

James Eddy, Technical Director at Bluesky International said: “We’ve introduced the new MetroVista product for smart cities and digital twin applications. The models are created as meshes but they are extremely dense so we’re looking to refine our technology to ensure that we offer energy savings, reduced data handling and can make data smaller without losing detail.

“With funded access from SPRINT to the expert team from the University’s Applied Mathematics Group, we aim to make the technology more accessible and open up to new sectors. 3D textured city meshes are rapidly becoming a standard data product in the geospatial industry and this SPRINT project will help us to accelerate the development of the technology and encourage people to get accustomed to it quickly.”

Dr. Alberto Paganini, Lecturer in Applied Mathematics at the University of Leicester added: “This SPRINT project provides an exciting opportunity to apply state of the art mathematics in industrial innovation. It will have considerable impact on making digital mapping technologies accessible to new users.”
