OSNI Open Data: River Basin LIDAR 2010 - DTMs and DSMs

Terrain (DTM) & Surface (DSM) elevation models of river basins derived from airborne LIDAR
survey systems. A Digital Terrain Model (DTM) is a digital file consisting of a grid of regularly
spaced points of known height which, when used with other digital data such as maps or
orthophotographs, can provide a 3D image of the land surface. This data is typically provided in
tiles of 1km x 1km, each containing elevations in a 1m x 1m grid. Tiles are grouped and can be
downloaded by area as shown on the index ‘River Basin LIDAR-Coverage Map’. Data acquired in
2009 & 2010 also contains Point Cloud files, a closely spaced (0.2m) irregular grid of elevations
from which the 1m x1m grids were derived. Please note that due to size constraints, the Ballymena datasets are split up.
By download or use of this dataset you agree to abide by the Open Government Data Licence. 
This data is not a supported LPS product, supporting documentation has been provided to assist /
offer guidance on the data itself.

Water Framework Directive (WFD) River Water Body Catchments Cycle 3 Classification 2022 (Full Resolution)

This is a polygon dataset showing Water Framework Directive (WFD) River Water Body Catchments. The catchments are associated with a single river water body.

This dataset also contains coastal catchments which are the areas of land that drain to coastal waters without passing through a defined WFD River Water Body. Coastal catchments usually include small streams with catchments less than 10km2, and all beaches.

This dataset provides attribution relating to the 2022 classification results, as well as other relevant information and data about each river water body.

Catchments are defined as an area of land from which all surface run-off flows through a series of streams, rivers, and possibly lakes, to a particular point in the watercourse such as a river confluence. 

This data also contains areas of land which drain directly to coastal or estuarine waters, rather than through a river water body. In these scenarios, the field in the dataset called 'water_body_id' is set to a number, and the field in the dataset called 'water_body_type' is set to 'Coastal Catchment'. 

Created using hydrological models based on EA LiDAR data informed with the Detailed River Network which has residual Ordnance Survey rights.

There is a layer file associated with this dataset, which is called WFD_River_Water_Body_Catchments_Cycle_3_Classification_2022.lyrx. Please note that there are limitations with the shapefile format of the data. The data applies to Cycle 3 of the WFD.

LIDAR DTM Time Stamped Tiles

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 England since 1998, with certain areas, such as the coastal zone, being surveyed multiple times. Data is available at varying resolutions of 25cm, 50cm, 1m and 2m, depending on project requirements. 
 
The DTM (Digital Terrain Model) is produced from the last return LIDAR signal. We remove surface objects from the Digital Surface Model (DSM), using bespoke algorithms and manual editing of the data, to produce a terrain model of just the surface.  

Available to download as GeoTiff rasters in 5km zipfiles, data is presented in metres, referenced to Ordnance Survey Newlyn and data aligned to the OS Grid. All LIDAR data has a vertical accuracy of +/-15cm RMSE. The transformation used on the data is specific to the time period of survey.  

Please refer to the metadata index catalogue which show, for any location, what time stamped data is available, the specific dates of survey, resolution of product and what transformation and geoidal model used.

Water Framework Directive (WFD) Surface Water Operational Catchments Cycle 3

This is a polygon dataset showing Surface Water Operational Catchments, created to meet the requirements of the Water Framework Directive (WFD). Operational Catchments are larger than catchments associated with water bodies, but they are smaller than Management Catchments. They contain multiple water bodies.

Operational Catchments are a way of grouping WFD Water Bodies together for the purposes of economic appraisal. Every water body has been assigned to an Operational Catchment. They are not always hydrologically correct catchments as the river water bodies may have been grouped based on pressures and measures than hydrology. The Surface Water Operational Catchments dataset also extends to cover Transitional and Coastal Water Bodies. It excludes the underlying groundwater, and linear artificial waters which are published separately.

Created using hydrological models based on EA LiDAR data informed with the Detailed River Network which has residual Ordnance Survey rights.

There is a layer file associated with this dataset which is called WFD_Surface_Water_Operational_Catchments_Cycle_3.lyrx. Please note that there are limitations with the shapefile format of the data. The data applies to Cycle 3 of the WFD.  Attribution statement: © Environment Agency copyright and/or database right 2024. All rights reserved.

Water Framework Directive (WFD) Transitional and Coastal Water Bodies Cycle 3 Classification 2019 (Full Resolution)

This is a polygon dataset showing Water Framework Directive (WFD) Transitional (Estuary) and Coastal Water Bodies.

This dataset provides attribution relating to the 2019 classification results, as well as other relevant information and data about each transitional and coastal water body.

It comprises both the transitional and the coastal water bodies used for the WFD. Article 2, clause 6 of the WFD defines transitional water bodies as ‘…bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but are substantially influenced by freshwater flows’. They are also referred to as estuaries. 

Transitional water bodies were defined from Mean High Water boundaries, taken directly from OS OpenMap - Local data, and Environment Agency estuarine boundaries defined for the Urban Waste Water Treatment Directive (UWWTD). 

Article 2, clause 7 of the WFD defines coastal water bodies as ‘…a surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters’. 

Coastal waters were defined by territorial waters 1 nautical mile from the Mean High Water coastline taken directly from OS OpenMap - Local data. The boundary between coastal and estuarine waters was delineated using Environment Agency defined transitional water bodies. Water bodies are also split and assigned to River Basin Districts.

There are three layer files associated with this dataset. There is a layer file called WFD_Transitional_and_Coastal_Water_Bodies_Cycle_3_Classification_2019_Chemical_Class.lyrx, a layer file called WFD_Transitional_and_Coastal_Water_Bodies_Cycle_3_Classification_2019_Chemical_Class_ex_uPBT.lyrx, and a layer file called WFD_Transitional_and_Coastal_Water_Bodies_Cycle_3_Classification_2019_Ecological_Class.lyrx. The layer files display the chemical status, and the ecological status or potential for each transitional and coastal water body. Please note that there are limitations with the shapefile format of the data. The data applies to Cycle 3 of the WFD. Attribution statement: © Environment Agency copyright and/or database right 2024.

LIDAR Time Stamped Point Cloud

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 Environment Agency.

The environment agecy site specific LIDAR DSM and DTM Time Stamped Tiles gridded raster products are derived from the point cloud. The component attributes a point cloud contains can provide valuable additional information to supplement elevation and can enable the user to make bespoke raster products such as canopy height models or intensity rasters. 

Site specific LIDAR surveys have been carried out across England since 1998, with certain areas, such as the coastal zone, being surveyed multiple times. The point cloud is available for surveys going back to 2006. Although the DSM and DTM Tile Stamped Tiles products are derived from the point cloud data there may not necessarily be a matching point cloud for each surface model due to historic data archiving processes.

During processing the point cloud classifies the laser returns in the 'ground' and 'surface objects'. Further manual editing undertkaen on the derived digital terrain model (DTM) means the classifed ground points in the point cloud data will not match the final derived DTM.

Data is available in 5km download zip files for each year of survey. Within each downloaded zip file are LAZ files aligned to the Ordinance Survey grid. The size of each tile is dependent upon the spatial resolution of the data. 

Please refere to the coverage metadata files for the start and end date flown of a survey as well as additional component information the point cloud contains such as the average point density. Attribution statement: © Environment Agency copyright and/or database right 2019. All rights reserved.
