TDOT 3 GREENTDOT 3 NIR
Use in aerial laser profiler (LP) alternative work
When laser surveying is used on slopes, the density of the laser point cloud changes the topography that is reproduced, and consequently the size of the hazardous areas that can be found. TDOT 3 not only provides an alternative to costly aerial laser profilers (LPs), but also eliminates the problem of missing hazardous areas with LPs because of the high laser density from low altitude.
With TDOT 3, it is possible to conduct reliable slope surveys.
With TDOT 3, it is possible to reproduce the topography with high-density point cloud data.

With TDOT 3, it is possible to reproduce the terrain with high-density point cloud data.
When using LP to survey slopes where vegetation is thriving, sometimes it is difficult to see even a steep cliff a few meters in size that is in danger of collapsing. Using TDOT, high-density laser beams on slopes from low altitudes can minimize the impact of thriving vegetation and extract subtle topographic changes.
