Orthophotography

Orthophotography (pronunciation: /ˌɔːrθoʊfəˈtɒɡrəfi/) is a branch of photogrammetry that involves the creation of orthophotos, which are geometrically corrected (orthorectified) images that represent the Earth's surface with uniform scale and true perspective.

Etymology

The term "Orthophotography" is derived from the Greek words orthos meaning "straight" or "correct", and photographia meaning "drawing with light". Thus, orthophotography can be interpreted as the process of creating 'correct' photographs.

Process

Orthophotography involves several steps, including the capture of aerial photographs, the correction of these photographs for lens distortion, camera tilt, and topographic relief, and the combination of these corrected images to create a seamless, geometrically accurate representation of the Earth's surface.

Applications

Orthophotography is used in a variety of fields, including cartography, geology, urban planning, environmental science, and civil engineering. It provides a true-to-scale, bird's-eye view of the landscape, making it a valuable tool for mapping, planning, and analysis.
