Abstract

Trees within Nacogdoches, Texas were measured for height using Pictometry hyperspatial imagery at 4 inch spatial resolution. Trees measured included baldcypress located on LaNana Creek as part of a hybrid analysis study. Baldcypress, Taxodiumdistichum, was planted along La Nana Creek, Nacogdoches, Texas, for erosion control and as a test bank for growth of the species genotypes. Each tree was located with GPS and entered into the GIS data base in the Arthur Temple College of Forestry and Agriculture, Stephen F. Austin State University. Actual tree height, measured using a height pole in 0.1 inch increments, was compared to tree height measured onscreen using Pictometry hyperspatial 4 inch spatial digital imagery. Remotely sensed tree height using Pictometry digital imagery was within 2.5 percent of actual height.

Results indicate that hyperspatial digital imagery is an effective and cost effective method to measure tree height in lieu of in situ measurements.
