Estimating Accuracy of Photogrammetric Data—Mechanism and Implementation
Publication: Journal of Surveying Engineering
Volume 124, Issue 4
Abstract
A method for estimating the accuracy of data collected from aerial photographs is presented. The emphasis is on its implementation in accuracy estimation when gathering data for digital terrain model databases. The method, based on error propagation of the photogrammetric solution process, facilitates the determination of accuracy for applications based both on direct photogrammetric measurements and on digital terrain model databases in addition to determining the measurements' accuracy. The mechanism and implementation at different levels of complexity is described, and various aspects of the proposed method are demonstrated, especially with applications dealing with the altimetric component of the terrain.
