摘要：Slope distance was measured between the top of 30 light poles and their respective ground level coordinate identified within a central parking lot on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Slope distance measured using Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery within a web based interface was compared to in situ total station and tape measured slope distance. The range for mean slope distance for Pictometry®, total station, and tape measured slope distance was 0.05 meters. Mean slope distance was 15.36 meters, 15.37 meters, and 15.41 meters for Pictometry®, total station, and tape measured slope distance respectively. An analysis of variance (ANOVA) between Pictometry®, total station, and tape measured slope distance resulting in a p-value of 0.9996 indicated there was not a significant difference between Pictometry®, total station, and tape measured slope distance. A two-tail t-test between the absolute difference between Pictometry® and tape measured slope distance and the absolute difference between Pictometry® and total station measured slope distance with a p-value of 0.6680 indicated there was not a significant difference between the two measurement errors. Results indicate that slope distance measured remotely with Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery within a web based interfaced can be used in lieu of in situ total station and tape measured slope distance.
