What is the process of converting aerial photographs into map products called?

Photogrammetry is the process of turning aerial photographs into map products. It uses measurements taken from overlapping images, often with stereo pairs, to determine precise 3D positions and elevations. By analyzing parallax—the apparent shift between photos as the camera moves—photogrammetry generates accurate base maps, orthophotos, contours, and digital elevation models. This approach specifically extracts spatial information from pictures to produce usable map outputs. Other terms describe related ideas but not the data-to-map conversion itself: remote sensing is about collecting data from sensors in space or air, lithography is a printing method, and cartography is the broader practice of making maps.
