A brief history of aerial photogrammetry

1480: The origin of photogrammetry goes back as far as 1480 when Leonardo da Vinci developed the concept of perspective and projective geometry.

1625: French mathematician Desargues defines projective geometry generalizing the use of vanishing points.

1840: The first use of photogrammetry was by the French geodesist Arago using a process called Daguerreotype.
