  • An asset used to control the flow of water

    Asset Sub-Types include: Control Gate, Draw Off Tower, Fish Pass, Hydrobrake, In Channel Stoplogs, Inspection Chamber, Jetty, Outfall, Screen, Spillway,...

  • This data shows the individual flood extents for all large raised reservoirs in the event that they were to fail and release the water held on a “dry day” when local rivers are at normal...

  • This data shows the individual flood extents for all large raised reservoirs in the event that they were to fail and release the water held on a “wet day” when local rivers had already overflowed...

  • This data shows the extent of river flooding added to the reservoir model to determine the impacts of failure on a wet-day. It is not exactly the same as the flooding from rivers shown in the Flood...

  • This record is for Approval for Access product AfA055. Flood Alert Areas are geographical areas where it is possible for flooding of low-lying land and roads to occur from rivers, sea and in some...

  • This record is for Approval for Access product AfA054 Flood Warning Areas. These are geographical areas where we expect flooding to occur and where we provide a Flood Warning Service. They...

  • This record is for Approval for Access product AfA439. A habitat map derived from airborne data, specifically CASI (Compact Airborne Spectrographic Imager) and LIDAR (Light Detection and Ranging)...

  • The Flood Map for Planning (Rivers and Sea) includes several layers of information. This dataset covers Flood Storage Areas. It shows those areas that act as a balancing reservoir, storage basin...

  • The data consists of separate packages of data for each large raised reservoir showing the flood extents for two scenarios; a “dry-day” and “wet-day”.

    The dry day scenario shows the flood extent...

  • Oblique aerial photography is an airborne mapping technique, which uses a professional grade DSLR camera to capture images out the side of our aircraft. Images are geo-referenced using our GPS...

  • The SurfZone Digital Elevation Model (DEM) was produced in 2019. Combining LIDAR and near-shore multibeam SONAR Bathymetry elevation data, it is the best currently available Digital Elevation Model...

  • Coastal Topographic Surveys are height transects that form part of the Anglian Coastal Monitoring Programme. A surveyor using a GNSS (Global Navigation Satellite System) staff will make...

  • Compact Airborne Spectrographic Imager is a multispectral pushbroom system that acquires data in visible and near infrared (VNIR) light. Unlike camera systems that generally acquire data in three...

  • Vertical aerial photography is an airborne mapping technique, which uses a high-resolution camera mounted vertically underneath the aircraft to capture reflected light in the red, green, blue and...

  • The estimated flood extent is an un-validated raw product often processed rapidly to share with category one partners during an incident. You must refer to the limitations of the data when using...

  • A saltmarsh habitat map derived from airborne data. The habitat map is a polygon shapefile showing site relevant habitat classes – this is a merged product of multiple sites across multiple...

  • The LIDAR DTM (Digital Terrain Model) Time Stamped Tiles product is an archive of raster elevation data produced by the Environment Agency. Site specific LIDAR surveys have been carried out across...

  • The LIDAR DSM (Digital Surface Model) Time Stamped Tiles product is an archive of raster elevation data produced by the Environment Agency. Site specific surveys have been carried out across...

  • The LIDAR Composite First Return DSM (Digital Surface Model) is a raster elevation model covering ~99% of England at 1m spatial resolution. The first return DSM is produced from the first or only...

  • The LIDAR Composite DTM (Digital Terrain Model) is a raster elevation model covering ~99% of England at 2m spatial resolution. The DTM (Digital Terrain Model) is produced from the last or only...
