Accurate 3D mapping can only be achieved via aerial drone surveying
that generates imagery data and can penetrate vegetation
Regardless if it’s a commercial or governmental activity, forest management requires data on forest to make proper decisions. Even if photogrammetry can be useful for tree species identification, it is not accurate for inside-canopy information and cannot give a precise information about DTM under dense vegetation. Hence, it cannot provide a reliable tree height measurement.
An airborne survey using YellowScan is the only way to penetrate the vegetation of a forest in order to produce a terrain model (DTM) and get inside-canopy information for tree species identification, height and size measurements or volume of wood per hectare information.
Key benefit of a UAV + YellowScan LiDAR system
- Higher accuracy of biomass estimation, under canopy layer and ground modelisation. Because the YellowScan can fly lower and slower than a standard airborne LiDAR, it provides a higher point density and more echoes under the canopy. This leads to a better classification of trees, a more accurate modelling of the canopy layers and ground topography. Thus, biomass estimation is more accurate.
- Autonomy: easy-to-use even by non-surveying professionals: you don’t rely on third-party experts or pilots
- Freedom of surveying when you want, where you want. Quick, light and easy mobilization: whole system can be carried in car trunk or airplane luggage
- Rugged & Reliable: compatible with most difficult field conditions (extreme temperatures, humidity, vibrations, dust…)
- Affordable exploration of limited areas (much cheaper than classical airborne LiDAR)
