Range 1500m PM-1500 Aerial LiDAR Scanner LiDAR Mapping System For Monitoring

FoV 75° accuracy 5mm@50m range 1500m PM-1500 2000kHz airborne LiDAR system for coastal zone sedimentation monitoring

Coastal zone is a special area of sea land interaction. Under the background of global sea level rise, coastal zone erosion disaster has seriously threatened the survival and living environment of coastal zone. The coastal zone is rich in tidal energy, wave energy, wind energy and other energy resources. At the same time, there are also sudden natural disasters such as storm surge and typhoon, as well as slow disasters such as coastal erosion, seawater intrusion, land subsidence, sea surface rise, sediment deposition in estuaries and ports. Due to the uncertainty, abruptness and severity of the surrounding environment of the coastal zone, it is very difficult to use traditional means to monitor, especially the large-scale sedimentation monitoring of the coastal zone. Airborne LiDAR system can efficiently obtain a large area of topographic data. Through the comparison and analysis of multi-stage data, it can monitor a wide range of coastal sedimentation.

Taking Fenghu VTOL UAV as the carrier, PM-1500 airborne LiDAR system can obtain the laser point cloud data of the coastal zone to be monitored in different periods. Through the pre-procesing of point cloud like denoising and thinning, the multi temporal terrain data of the monitoring area is generated by interpolation. Comparison of the topographic data of different phases can objectively analyze and evaluate the sedimentation of a wide range of coastal zone.
