The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Waldmonitoring unter besonderer Berücksichtigung der aus Stereoluftbildern abgeleiteten 3. DimensionSysavath, Vithoone 13 July 2009 (has links) (PDF)
Results of the investigation has been presented to derive digital elevation models of forest areas for the determination of the parallax measuring accuracy from AATE (Adaptive Automatic Terrian Extraction) with the PCI software Geomatica. It has been used the informations from the threefold overlaps of aerial stereoscopic pairs. The parallax measuring errors on forest areas are three times larger than on the arable and pasturelands. It has been shown that the third dimension can be used for the derivative of crown of tree profiles and their roughness and the rates of timber growth can be derived with sufficiently high accuracy from the repeatability flying.
