Investigation Into a Methodology of Establishing an Areal Terrain-Data Base

摘要

This volume contains a compilation of vegetation field data, statistical stand table data and current forestry inventory data for a selected area of the FRG within two 1 : 50,000 scale quadrangle sheets Lauterbach (L 5322) and Hunfeld (L 5324). The data were used for assessing the applicability of existing vegetation terrain data modeling at the WES and necessary improvements. For these purposes, the four dominant German forest species (beech, oak, pine, spruce) were investigated. An approach was made to analyze current inventory data from forestry management books for selected compartments, modifying stand table data from statistical data sources plus investigating some selected field sites according to the common WES vegetation sampling procedures. Finally, a first evaluation on the feasibility of aerial photo interpretation was made for selected species found in West German forests. General procedures for predicting vegetation characteristics were derived for the species investigated. (Author)
