The Digital Terrain Model (DTM) is a bare earth model, posted at 5m with a vertical accuracy of less than 60cm RMSE (root mean square error). The model represents the bare...

As one of our range of backdrop mapping products, Ordnance Survey's 1:25 000 Scale Colour Raster is backdrop map data of our popular OS Explorer Map series for outdoor...

This is a high resolution spatial dataset of Digital Terrain Model (DTM) data in South West England. The DTM along with a Digital Surface Model (DSM) cover an area of 9424 km2...

The Digital Elevation Model (DEM) domain includes the tidally influenced Conwy estuary, downstream of the Cwmlanerch river gauge on the River Conwy and extending offshore into...

This is a high resolution spatial dataset of Digital Surface Model (DSM) data in South West England. It is a part of outcomes from the CEH South West (SW) Project. There is also...

Hydrologically corrected digital terrain model (DTM) of Plynlimon catchments. The DTM was derived from digitised elevation data from scanned topographic maps.

The dataset details global positioning system (GPS) locations recorded for survey quadrats at six UK saltmarsh sites. Three of the sites were in Morecambe Bay, North West...

This resource is the raw data from a topographic survey of the Sourhope field experiment site, conducted by the Department of Environmental Science, University of Stirling in...

The Most Probable Overland Flow Pathway dataset is a polyline GIS vector dataset that describes the likely flow routes of water along with potential accumulations of diffuse...

Elevation contour lines within the Wye catchment at 10 and 20 metre intervals. The contour lines have been digitised from a scanned topographic map.

The Environment Agency National LIDAR Programme provides accurate elevation data at 1m spatial resolution for all of England. In 2017 we divided the country into 302 survey...

Multibeam echo sounders, for Bathymetric survey, use sonar pulses to measure the distance between the survey vessel and the seabed. This instrument collects point data at a...

The LIDAR point cloud is an archive of hundreds of millions, or sometimes billions of highly accurate 3-dimensional x,y,z points and component attributes produced by the...

The Environment Agency LIDAR Ground Truth surveys dataset is an archive of elevation points and attribute information that have been independently surveyed to verify the...

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...

This dataset is retired and no longer available on the Data Services Platform. The Environment Agency Geomatics team no longer produce a 25cm resolution composite product. This...

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...

The LIDAR derived Vegetation Object Model (VOM) is a raster product produced as part of the Environment Agency’s “Keeping Rivers Cool” project. It is an attempt to identify...
