Bluesky 3D Terrain Models Upgrade Ambiental Risk Analytics’
3D models derived from high resolution aerial photography are underpinning the most up-to-date flood risk map of the UK. Working alongside Ambiental Risk Analytics (ARA), aerial mapping company Bluesky has supplied photogrammetrically derived Digital Terrain Models (DTM) for the whole of England, Scotland and Wales. Combined with river flow and rainfall data these 3D models allow ARA to deliver a range of flood risk information for any property in the UK.
“Our flood map products are used around the world by insurers, government agencies, property developers and emergency response services to visualise, assess and understand potential flood risk,” commented Mark Nunns, Technical Account and Sales Manager at ARA. “This means they need to be accurate, up-to-date and easy to use. Working with Bluesky we have been able to increase the accuracy, detail and cover of the topographic data outside of other LiDAR coverage. This allows for a more accurate flood model output and a better representation and understanding of flood risk.”
Also known as bare earth models, the Bluesky height models were used to enhance ARA’s national scale topographic flood map dataset UKFloodMap. Using proprietary software Flowroute-i, ARA has integrated the Bluesky DTM data to provide an accurate ground elevation surface over which different water flows can be modelled. UKFloodMap includes all primary flood sources, including...
