Lidarfinder.com Website Review

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 (Digital Surface Modelling) includes all terrain and above-terrain features (e.g. buildings, trees etc). DSM (Digital Terrain Modelling) includes only terrain features and filters out above-terrain items. It can be useful in situations such LIDARfinder lets you uncover hidden features under the ground by showing you a split-screen view of a map and its corresponding LIDAR LIDARfinder uses publicly-available LIDAR data. Currently, only LIDAR data for England and Wales is available and not all areas are covered. 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 Use the mouse to drag and centre the map as usual.
