Case Applications for Forest Resource Assessment Using Airborne Laser Scanner
Three case applications for forest resource assessment using airborne laser scanner (LiDAR) will be introduced. The first case is “assessment of high density forest area”. The area where forest maintenance is necessary is extracted using colour composite of three layers developed from laser point group; (1) attained distance from DSM into forest (2) tree height (3) reflection intensity. The sec...
متن کاملA Quality Assessment of Airborne Laser Scanner Data
A Toposys-1 airborne laser scanner (ALS or LIDAR) measurement campaign was arranged in June 2000 (Kalkkinen) and another campaign with helicopter-borne TopEye laser scanner was arranged in September 2002 in southern Finland (Masala, Otaniemi). The Toposys flying altitudes were about 400 and 800 m above ground and for the TopEye, 100, 200, 400 and 550 m flying altitudes were used. Reference meas...
متن کاملLaser-based Field Measurements in Tree-level Forest Data Acquisition
Remote-sensing (RS) methods, such as airborne laser scanning (ALS), are capable of acquiring tree-level forest information with high accuracy. However, these methods need more detailed reference data from sample plots than standwise mean characteristics. Field-measured treewise characteristics must be matched with ALS data on the measured position of the tree. In addition to tree position and s...
متن کاملEstimating Forest Structure Indices for Evaluation of Forest Bird Habitats by an Airborne Laser Scanner
Bird species diversity is affected by the vertical and horizontal diversity of forest structure; therefore, several indices of forest structure have been proposed for the evaluation of bird habitats. If these indices could be measured in a wide area by remote sensing, it would be very useful for wildlife habitat assessment. The indices that we evaluated based on whether they can be estimated fr...
متن کاملEstimating Leaf Area Index in Mixed Forest Using an Airborne Laser Scanner
Leaf area index (LAI) is one of the most important parameter of forest structure. The study site was an isolated forest in Kyoto City in Japan and it vegetation type was mixed forest. We took fisheye photos at 102 points in the study area, and calculated the LAI and Canopy-open. We classified the laser data into 4 classes, that is, First pulse, Last pulse, Only pulse and Ground pulse. We counte...
