Historic LiDAR Archive
A tile catalogue of Historic LiDAR DTMs and DSMs in Wales provided by Natural Resources Wales with download hyperlinks.
This is a temporary asset provided until a more permanent solution is developed through the Welsh Government Lle portal. As such it is liable to change.
The data are available, depending on time and location, in resolutions between 0.25 and 2m. In some locations there will be more than one tile, corresponding to multiple historic dates of capture.
The fields DSM_URL and DTM_URL contain links to the Digital Surface Model and Digital Terrain Models. These can either be copied and pasted into a browser, or set up as clickable hyperlinks in GIS software.
For earlier LiDAR capture, between 1998 and 2002, sometimes only the DSM was made available.
An alternative means of accessing the data is provided through a temporary web map available Here.
To download DSM or DTM data using this map, click on the tile of interest and, in the popup, on the link(s) marked "More Info". In locations where there is more than one historic tile available, or where tiles of differing resolutions are available, these will denoted by "1 of x" at the top of the popup. Clicking the left and right arrows will cycle through all the available tiles.
