Abstract

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 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 DSM (Digital Surface Model) is produced from the last return LIDAR signal and includes heights of objects, such as vehicles, buildings and vegetation, as well as the terrain surface. Available to download as Geotiff rasters in 5km zips, data is presented in metres, referenced to Ordinance 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.

Quality and validity

Lineage

Light Detection and Ranging (LIDAR) is an airborne mapping technique, which uses a laser to measure the height of the terrain and surface objects on the ground such as trees and buildings. Hundreds of thousands of measurements per second are made of the ground allowing highly detailed terrain models to be generated at spatial resolutions of between 25cm and 2 metres. The vertical accuracy of the LIDAR dataset is +/-15cm RMSE.
