Photogrammetry is the science of obtaining reliable information about physical objects through analyzing photographs. It involves recording, measuring, and interpreting images and patterns of electromagnetic radiation. There are different types of photogrammetry based on the distance from the camera to the object, including close-range photogrammetry from distances less than 10 meters, terrestrial photogrammetry from 10-100 meters, aerial photogrammetry from 2-10 km, and space photogrammetry from 30+ km. Photographs can also be categorized by tilt, including vertical, low oblique, and high oblique. Vertical aerial photographs are taken in parallel strips with overlap between photos to allow measurement. Photogrammetry has advantages like extracting geometric data cheaply and quickly to
