1. A forest resource information generation structure for generating forest resource information using point cloud data of forest resources, the point cloud data being acquired via a remote sensing technique, the structure comprising:
a tree top detection processing section for obtaining tree top information, and
a breast height diameter calculation processing section for obtaining breast height diameter information, the structure further comprising:
a tree trunk detection processing section for obtaining breast height part information based on terrain height information obtained from the point cloud data and the tree top information,
wherein the breast height diameter information is generated by the breast height part information being subjected to processing in the breast height diameter calculation processing section; and
wherein the forest resource information generation structure further comprises a breast height diameter reliability addition processing section for evaluating reliability of the breast height diameter information generated in the breast height diameter calculation processing section, wherein in the reliability addition processing section, reliability information for evaluation of whether or not the breast height diameter information has reliability, the reliability information being determined according to comparison between the breast height part information in a two-dimensional form and the breast height diameter information generated by the breast height diameter calculation processing section, is added to the breast height diameter information.
