Possibilities to determine biometric parameters using airborne laser scanning data

The paper brings forward ways to solve the problem of estimating trunk diameter using data airborne laser scanning (LIDAR) relevant for forest inventory. At first stage studying, it was defined regularities tree height and relations various species, as well coefficients coupling equations significance “height-diameter” based on field data. second stage, calculated crown parameters (diameter volume) at 1.3 m level accounting dependent species. Based estimated LIDAR data, resulting calculations diameters were made with 83.2% accuracy. proposed calculation is an important step further development automated algorithm obtain basic taxation indicators, such number, diameter. got by this way can be used high density forests while cuttings assessment LIDAR.
