Orthorectify is a technical term often used in geographic information systems (GIS). It refers to the process of correcting the geometric shape and spatial orientation of an aerial or satellite image to remove distortions or misalignments caused by the terrain or the camera's viewpoint. There are several synonyms that can be used for the word orthorectify depending on the context or the level of precision required. These synonyms might include georeferencing, rectification, registration, alignment, projection, calibrating, resampling, warping, or re-projection. All of these terms relate to the process of transforming raw image data into accurate, reliable, and useful geospatial information.
