To address the critical issue of terrain instability in a dense woodland area in North Wales, OR3D GEO was approached by the National Forestry organization to assess landslide risks. The project focused on creating precise elevation models that would aid in identifying high-risk zones and implementing effective mitigation strategies. The YellowScan Surveyor Ultra LiDAR system was employed due to its exceptional ability to penetrate dense vegetation and capture detailed elevation data. The survey covered 60 hectares and was completed in a single 30-minute flight at 50 meters altitude. The LiDAR system’s high pulse rate of 640,000 lines per second, combined with its capability to capture up to three echoes per shot, delivered high-resolution data with accuracy of +/- 25mm and precision of +/- 30 mm. The collected data enabled the creation of Digital Elevation Models (DEMs), Digital Surface Models (DSMs), and Digital Terrain Models (DTMs). These models revealed critical terrain features such as slope gradients, drainage patterns, and erosion-prone areas, which are crucial for predicting and managing landslide risks.
