By utilizing image rectification, an analyst can take an image that does not have projection info, and effectively lay it over another image that has a stated projection. While modern imagers (even consumer cameras) have the ability to add GPS data to an image, this is a new technology. The ability to rectify any image can aid historical research projects. Areal photographs taken from airplanes or hot air balloons can now have projection info added to them. This will allow researchers to accurately study an area for changes to agriculture or wilderness or to determine old property lines.
There is also the possibility to inaccurately rectify an image, either through a lazy analyst or poor image quality. If this is done, decisions can be made that are based on data that is inaccurate and therefore misleading. Caution would be needed, as well as other outlets of information, in order to make informed decisions based on image rectification.
