Evaluation of airborne laser scanning data for tree parameters and terrain modelling in forest environment
Original language description
The aim of this article is to analyse possibilities of airborne laser scanning (ALS) data utilization in forestry, especially for the purposes of terrain modelling and for forest inventory (determination of forest height, diameter breast height and volume -- DBH). The accuracy of ALS data in forestry was tested on the area of 1.5 ha. On this area the topography and location of all trees as well as their heights were surveyed in detail by means of total station. Firstly, the altitudinal accuracy of ALS for the creation of digital elevation model (DEM) was evaluated, based on the comparison with relief measurement. The research also evaluated different data sources from various types of scanners with a different point density per m2. Further, we comparedtree heights determined from ALS data by different ways of interpolation into canopy height model (CHM) with the surveyed data, following calculations of DBH (diameter breast height) and tree volume based on the regressions.
