Bluesky's 3D aerial maps inform flood risk assessments

摘要

Aerial photography and detailed 3-dimensional (3D) height models are being used to assess the risk of flooding and help development projects progress through the planning process. Working with Betts Hydro, part of the UK engineering consultancy group Betts Associates, the geographic datasets from Bluesky are providing ground level information for use within a number of applications, including flood risk assessments, flood consequence assessments, and hydraulic assessments. The data, high-resolution aerial photography, LiDAR (Light Detection and Ranging) measurements and 3D models (Digital Terrain and Digital Surface Models), used by Betts Hydro, are downloaded from Bluesky's online Mapshop.
