WebLiDAR sensors are able to achieve range accuracy of 0.5 to 10mm relative to the sensor and a mapping accuracy of up to 1cm horizontal (x, y) and 2cm vertical (z). This makes them particularly useful as a remote sensing tool for mobile mapping. Additionally, LiDAR sensors are able to collect multiple returns from a single light pulse. Web04. apr 2024. · The resulting canopy height histograms were thus, in effect, converted to maps with 90 layers (90 bins per histogram per cell), and each layer records the lidar sample count within the range of the height bin. In addition, map layers associated with average canopy height and sample point density within each cell were generated.
