Abstract

Digital photogrammetry provides an opportunity to automate the measurement of tree heights. A sufficiently
dense canopy model with tree height data at nearly 100% sampling rates has the potential to improve
significantly the reliability of strategic and operational forest inventory. This study investigates the utility of
digital photogrammetric techniques to map tree height within radiata pine plantations. A digital
photogrammetric workstation, the Leica Helava DPW 770, was used to generate digital canopy models (DCMIs)
of both closed canopy and thinned stands. The performance of the workstation and several post-processing
filters were assessed using scanned aerial photographs of different film types and scales, including colour, black
and white.
