Access TutorialThe super registration algorithms can co-register images with up to 1/10th of a pixel accuracy to reduce the risk of misalignment errors. This misalignment can be caused by poor math models (e.g. inaccurate GCPs), a low quality elevation model or distortions in the camera lens. Poor alignment can make some types of analysis, such as change detection, very difficult.
