Abstract
The term photogrammetry has various meanings for different application areas and over time, it has changed its definitions depending on the technological stage of its development. Currently, the most adequate definition is to consider it as the methodology for modelling 3D space from 2D images generated by digital sensors. In the beginning, it was just photogrammetry which became Analog Photogrammetry, Analytical Photogrammetry and finally, Digital Photogrammetry, which is being replaced by two competing terms which are conventional photogrammetry and UAV-photogrammetry. The question here is whether they are sufficiently different to deserve two distinct denominations.
