FOREST RESOURCE INFORMATION GENERATION STRUCTURE AND FOREST RESOURCE INFORMATION GENERATION METHOD

摘要

A forest resource information generation structure and a forest resource information generation method enable more efficiently grasping forest resource information via direct measurement of a breast height diameter with no need for an actual measurement data collection process such as a ground survey are provided. A forest resource information generation structure 100 is a structure for generating forest resource information using point cloud data D00 of forest resources, the point cloud data D00 being acquired via a remote sensing technique, and includes a tree top detection processing section 10 for obtaining tree top information D10 and a breast height diameter calculation processing section 35 for obtaining breast height diameter information D35, and further includes a tree trunk detection processing section 30 for obtaining breast height part information D30 based on terrain height information obtained from the point cloud data D00 and the tree top information D10, and the breast height diameter information D35 is generated by the breast height part information D30 being subjected to processing in the breast height diameter calculation processing section 35.
