Highly detailed, three-dimensional representations of environments.
LiDAR uses laser pulses to measure distances to the target surface. It works by emitting laser light and measuring the time it takes for the light to return after hitting an object or surface. By employing laser light to measure distances with exceptional precision, LiDAR systems generate highly detailed , three dimensional representations of environments.
Capturing Fine Detail
OR3D GEO utilises the Yellowscan Ultra 3 LiDAR unit emitting 640,000 lines per second and 3 Echoes per shot, achieving exceptional accuracy (+/- 25mm) and precision (+/- 30mm) in distance measurements. This technology captures highly dense point clouds perfect for bridge inspections and civil infrastructure and plant projects . Penetrating forest/woodland canopies and heavily vegetated ground to capture the true ground level beneath to produce highly detailed digital terrain models (DTMs). Being laser based it will operate in all lighting conditions, including night time.
Aerial LiDAR is used for capturing large areas such as forests, farmland, energy and utility sites
Forestry: LiDAR is capable of penetrating vegetation, allowing the measurement of tree height, canopy structure, and biomass, creating detailed 3D models. This allows for accurate forest inventory, monitoring changes, assessing health, and managing resources effectively to support conservation and sustainable forest management.
Agriculture: LiDAR in agriculture provides detailed 3D models for precision farming, optimising planting, monitoring growth, assessing yield potential, and improving overall farm efficiency and sustainability.
Environmental monitoring: LiDAR creates highly detailed and accurate maps of terrain features. Maps with a high level of detail can help identify potential environmental risks, such as erosion, deforestation, and habitat destruction.
Energy and Utility Sites: Aerial LiDAR (Light Detection and Ranging) technology is increasingly being used for energy sites due to its ability to provide high-resolution, accurate and detailed spatial data.
Nature Reserves: Accurately monitor and assess the ecological health and stability of nature reserves, providing detailed elevation data and vegetation analysis even in densely vegetated and challenging terrains.
Advanced LiDAR Techniques for Landslide identification
OR3D GEO was approached by a National Forestry organisation to assess landslide risks in a large woodland area prone to terrain instability and erosion. Traditional survey methods were inadequate due to the dense vegetation and challenging terrain. OR3D GEO employed LiDAR technology to conduct a comprehensive assessment. They deployed airborne LiDAR sensors to capture detailed elevation data, which was then processed to generate Digital Elevation Models (DEMs) and point cloud data, revealing subtle changes in terrain morphology.
By analysing the LiDAR-derived topographic maps, OR3D identified areas with steep slopes, potential drainage issues, and signs of previous erosion—key indicators of landslide risks. Visual representations of the terrain were created, along with GIS-compatible maps highlighting landslide-prone zones. Detailed reports outlined the findings and recommended mitigation strategies. The LiDAR-based assessment provided actionable insights, enabling the client to prioritise preventive measures, such as reinforcing slopes, improving drainage, and implementing monitoring systems to enhance forest resilience and safety.
Eliminate the need for personnel to access hard-to-reach areas, such as bridges, power lines, or tall buildings.
LiDAR and photogrammetry are two methodologies used to create detailed 3D models and maps of environments. Both techniques have their unique strengths, limitations, and suitable applications.
Using the Elios 3, OR3D GEO capture detailed visual data of the confined space, enabling inspectors to identify potential issues such as corrosion, leaks, cracks, or structural damage.
