Aerial LiDAR used to survey a large heavily vegetated area for planning and design purposes
The 25cm grid level DSM and DTM was used for planning and design purposes. Aerial LiDAR can collect over 700,000 points per second with an average surface density of >700 points per square meter.
We used aerial LiDAR to survey a heavily vegetated area of long grass, brambles and trees to understand ground levels and the terrain. The large area was inaccessible using traditional surveying methods and very unsafe.
Sometimes it’s not possible to navigate around a large area due to heavy vegetation and sometimes a traditional survey is not possible without expensive vegetation clearance. Using aerial LiDAR overcomes these major issues as the data is captured from the air using a drone with a specialised LiDAR unit attached.
Aerial LiDAR can be used for forest inventory, floodplain mapping, hydrology, landscape ecology, coastal engineering, landslide monitoring, erosion and deformation monitoring, survey assessments and volumetric calculations.
