Plate motion correction in satellite bundle block adjustment

Abstract

Plate tectonic movements can cause drift in the position of common points used in generating maps, such as ground control points and tie points. Over time, if not corrected for, plate tectonic movement results in older images no longer accurately reflecting the ground position of the imaged features. Furthermore, plate tectonic movements are not uniform across the world and can vary significantly in direction and velocity from region to region across the globe, or between images, or even within a single image. Several methods for accounting for these movements are described herein that can use images at different times to more accurately indicate current ground coordinates by applying plate tectonic movement information.
