摘要

This paper describes the results of the manipulation of high resolution stereo satellite images for forest inventory purposes. The approach used the softcopy photogrammetric workstation LH Systems DPW 770, panchromatic IRS-1C imagery and digital aerial imagery. The study was conducted over various sites with pine and eucalypt in the Sabie area in South Africa. The extraction of stand parameters such as tree/stand height has been performed manually, semi-automatically and automatically. The manual extraction of elevation information from the satellite imagery has been very promising featuring deviations from the terrestrial values of about +- 5%. However, the automatic determination of tree heights in the IRS-1C imagery has failed to yield useful results. The results are of considerable relevance to those concerned with the inventory of vast, inaccessible forest areas and for those searching for highly efficient, cost-effective schemes.
