Digital Terrain Model of the Krycklan catchment, created by Gudrun Norstedt 20170824 The data set was produced by TerraTec Sweden AB in August 2015 on demand of the Department of Forest Resource Management at the Swedish University of Agricultural Sciences. The average density of the data set was 20 pulses/m2. Ground point classification was performed with lasground_new (included in LAStools, a software suite produced by rapidlasso GmbH). The following parameter settings were used in the command line: "-step 10.0 -offset 0.05 -spike 1 -buffered 20 -remain_buffered". The DTM was created with Quick Terrain Modeler, v8.0.6.3. The following settings were used: Processing Options = Process as Group. Grid sampling = 0.5. Gridding options = Adaptive triangulation, Mean Z, Apply Antialiasing, Smoothing filter = None, Remove spikes at minimum spike level = 10 m. Only ground points were imported. The coordinate system of the original file was set to WGS 84/UTM zone 33N with linear units = metre. The coordinate system has (in the available file) been transformed to SWEREF99 by William Lidberg at the Department of Forest ecolocy and management at the Swedish University of Agricultural Sciences.
