Abstract
This report presents a practical method for estimating registration mapping error for a given relief and satellite attitudes. This method relies on a simulation using a digital elevation model to calculate the mapping error for a set of parameters. The method was applied to a test set of digital elevation models showing diverse terrain reliefs: flat, pretty flat, mountainous, and mountainous near a coast. Mapping error increases for terrains with more relief; but this error can be reduced by using local mapping algorithms, which were found to decrease mapping error for mountainous regions by 80%. Our method quantifies the mapping error and compares the mapping error for diverse conditions. These results can then be used to delimit the change detection capability and to better plan future image acquisition missions.
