摘要：Urban forests are important as valuable green resources to give moisture and tranquillity of mind in our living, requiring an efficient control of forest increase/decrease and growth rate. In this study, we conducted tree-height measurements using LIDAR data different in resolution at urban parks in the suburbs of Tokyo, and investigated the measuring characteristics. As a result, for conifers, LIDAR data of high resolution (1 m) of high treetop irradiating probability showed higher measuring accuracy. For trimmed broadleaf trees, on the other hand, the LIDAR data of low resolution (2 m) of low penetration probability between branches showed higher measuring accuracy, indicating that the tree-height measuring accuracy by the LIDAR data does not necessarily depend on the resolution
