Fig. 4From: The use of terrestrial LiDAR technology in forest science: application fields, benefits and challengesImpact of climatic and sky conditions on scan quality. Wind leads to poor descriptions of tree axes (a), whereas snow intercepts laser beams and leads to an increase of noise points (b) and poor adjustments of geometrical shapes on both spheres and trees (c). The high reflectance of the sun causes information to be ignored by the scanner (d)Back to article page
