What is the difference between a georeferenced a rectified and an orthorectified photograph?

Georeferencing is the process of projecting and thereby assigning coordinates (e.g. latitude and longitude) to an image. … Orthorectification is the process of removing internal and external distortions to assign more accurate coordinates to the final image.

What is the difference between Georectified and georeferenced?

Georeferencing is the recording of the absolute location of a data point or data points. Georectification refers to the removal of geometric distortions between sets of data points, most often the removal of terrain, platform, and sensor induced distortions from remote sensing imagery.
