Abstract

The aim of this study was to elaborate the semiautomatic method of airborne laser scanning (ALS) point-cloud data processing for revising a digital forest map in the Tatra National Park, Poland, and updating attributes stored in its descriptive forest database. We proved that elements such as gaps, clearings, biogroups, dead trees, wind-damaged trees, and areas of low canopy closure could be detected with high accuracy, based on this light detection and ranging technology. By using this method and geographic information system techniques, we were able to update selected attributes of the descriptive database, such as forest stand height, which were collected during earlier forest inventories. Moreover, parameters of some parts of forest stands, such as those growing on extremely steep slopes or isolated ledges that are hard to determine using traditional methods, are easily measured with ALS technology. The difference in stand height using the ALS method and that measured by the traditional forest inventory was equal to 1.58 m (2.87 m for absolute differences).
