These settings affect how the lidar layer is displayed.
LiDAR is a technology which uses laser light to create a 3D representation of the earth's surface. It can be used to find archaeological features which are not immediately visible from the ground or through traditional satellite images.DSM LiDAR
DSM (Digital Surface Modelling) includes all terrain and above-terrain features (e.g. buildings, trees etc).DTM LiDAR
DSM (Digital Terrain Modelling) includes only terrain features and filters out above-terrain items. It can be useful in situations such as when researching a heavily wooded area.
LiDARFinder lets you uncover hidden features under the ground by showing you a split-screen view of a map and its corresponding LiDAR view.
LiDARFinder uses publicly-available LiDAR data. Currently, only LiDAR data for England and Wales is available and not all areas are covered. New data will be added as and when it becomes available.
On startup, LiDARFinder will show you a random interesting location. If you have granted the site location permissions, it will move to your current position. If you are using a mobile device, the map will keep following your current location until you centre the map somewhere else.On desktop
Use the mouse to drag and centre the map as usual. Click near the boundary where the two views meet and drag to change the proportion of the map and LiDAR view.On a mobile device
Tap on the map to re-centre or drag it. Tap and drag near the boundary where the two views meet to change the proportion of the map and LiDAR view.
Click the search icon to find a location. Enter a place name or postcode and select the appropriate match from the drop-down list. The map will move to that location.
Click on the target icon to move the map to your current location. If you are using a mobile device, the map will move with you until you centre the map somewhere else.
Tap the cog icon to access the settings menu.
Note: All settings will be 'remembered' by your web browser so the next time you visit LiDARFinder on the same device, everything will be set up the way you last left it.Map settings
Map layer - select the type of map you want LiDAR type - select DTM or DSM data (see What is LiDAR?) LiDAR overlay - choose whether to overlay street information on the LiDAR view. Flip map layers - view LiDAR in the top half of the screen and maps in the bottom half, or vice versa.LiDAR filters
LiDAR data is provided in 'false colour'. Use the options in this tab to adjust the colour, brightness, contrast and saturation of the LiDAR data.Mobile settings [only available on mobile devices]
Follow my location - turn 'follow me' mode on and off Optimise for Retina devices - this improves image quality for some Apple devices with Retina screens.Restore Defaults
This option resets all settings to their default values.

LiDAR Finder has now been updated to include the NR Wales 2020-2022 DSM coverage data.
This is good news for Welsh users as previous coverage was quite slim. DTM coverage is unfortunately still based on the previous flood risk data but we are waiting to see if and when DTM full coverage will become available.
