Abstract
We compared the horizontal accuracy of forested wetland boundary delineations obtained from large-scale, natural color aerial photography against delineations obtained from 'heads-up' digitizing of digital orthophotography. The absolute value of the mean (±SD) distance between the field-derived 'true' wetland boundary location and the orthophotograph-derived wetland boundaries was 3.4 ± 3.4 m and was slightly more accurate than the mean distance between the 'true' boundary and the aerial-photo-derived wetland boundaries (4.5 ± 4.0 m). Field visitation increased the accuracy of delineating wetland boundaries, and the majority of wetland edges-both orthophotograph- and photo-derived-were placed on the wetland side relative to the 'true' boundary.
