Downloading Survey Data

Created: 31 October 2023

The Defra Survey Data Download allows the download of pre-defined zip files containing titles of data for the various Survey datasets from different years and resolutions. It can be accessed through the Survey tab on the DSP Homepage.

A list of Operational layers is displayed. The layers can be togged on and off to see what is available in an area of interest. The layers do not need to be selected to be downloadable.

Downloading data

There is the option to either draw a polygon or upload a shapefile of an area of interest using the download tab. A registered user of the DSP will have a predefine area of interest displayed. By clicking ‘Get available tiles’ a list of tiles will appear that are available for download.

The tiles available for download are organised based upon product, year and resolution in three lists.  There may be a delay of up to a couple of minutes while the data is prepared before the download starts. If the area you've selected is too large, you may need to submit a Large Data Request.

For more information about the Survey data provided, see the Geometrics Story Map.

Data Formats available

All LIDAR data is available in GeoTiff format. The tile size is dependent on the source resolution. The National LIDAR Programme and LIDAR Composite data is available in GeoTiff format, supplied in 5km tiles. All LIDAR Point Cloud data is available in .laz format, which is the compressed form of .las files.
