Arrangement of terrestrial laser scanner positions for area-wide stem mapping of natural forests.

Popis výsledku v původním jazyce

With the development of terrestrial laser scanning and applications in forestry, the question arises as to how the scanners should be ideally placed for the best possible data acquisition. We searched for an optimal scanning distance for recognition of stems in natural beech-dominated forests, focusing particularly on the shading effect of tree stems and terrain. Recognised tree stems in TLS point clouds were compared with reference stem maps. A GIS based visibility simulation was carried out to enhancethe quantitative assessment and generalizability of results. The analyses also include the additive effect of multiple scanning positions. Single scans only have a tree recognition rate above 80% up to a distance of 15 m from the scanner; using at leastthree scanning positions a comparable recognition rate was attained up to 20--25 m. A simulated coverage of a beech-dominated natural forest by laser beams using a 40 m square grid of scanning positions captured at least half of the stem
