Total System Accuracy for APPS (The Analytical Photogrammetric Positioning System)

Abstract

The accuracy and speed with which experienced APPS operators can obtain UTM coordinates and the elevation above the datum plane for points of interest designated on various reconnaissance imagery types were determined. These points of interest were transferred by an analytical method from representative operational imagery--panoramic photography, infrared, and radar-- to 1:100,000 scale data base photography and their UTM coordinates and elevation above the datum plane determined. Results were compared with known values and error magnitudes and performance time requirements obtained. Results indicate that experienced APPS operators are very consistent in their placement of points of interest under the reference dot (monocular pointing). The median variability error was 1.6 meters in the XY-plane. Time required per point for monocular pointing was about .18 minutes.
