Image Rectification

Image rectification is very useful because it allows the viewer to see actual structures and the lay of the land that is geographically accurate. A great example of this is when the landscape has been changed due to an extreme disaster and first responders need accurate maps to be used from the ground. As useful as image rectification is, there are pitfalls. If the image is out of date and the landscape has changed considerably, it could actually become an impedance. The same applies to images that have been rectified poorly.
