我们比较了由大比例尺自然彩色航空摄影获得的森林湿地边界的水平精度与由数字正射影像的平视数字化获得的边界的水平精度。野外真实湿地边界与正射影像湿地边界之间的平均距离(±SD)绝对值为3.4±3.4m，略高于实际边界与航空摄影湿地边界之间的平均距离(4.5±4.0m)。实地考察提高了划定湿地边界的准确性，大多数湿地边缘--无论是正射照相还是从照片中提取的--都放置在湿地一侧，相对于真正的边界。
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.
