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.
1849: Frenchman Laussedat referred to as the “father of photogrammetry” was the first person to use terrestrial photographs for topographic map compilation.
1858: The first aerial photogrammetry was tested by Laussedat using kites and in 1862 using balloons.
1865: Italian geodesist Porro designed the photogoniometer, this development is significant in photogrammetry because of its application in removing lens distortion.
1893: Meydenbauer was the first person to use the term “photogrammetry”.
1896: Canadian Surveyor general Deville created the stereo-planigraph: the first stereoscopic-plotting instrument.
1899: German Finsterwalder describe the methodology of relative and absolute orientation.
1901: German physicist Pulfrish designed the first photogrammetric instrument.
1903: Airplane invented by Wright brothers
1908: The first aerial photography captured from a plane for mapping purposes was done by Italian Captain Cesare Tardivo
1914: American Brock brothers develop the first aerial camera that was mounted in the plane instead of holding the camera over the side.
1924: Fairchild create mosaic of Manhattan Island with over 100 aerial photos. He played a very important role in developing specialized aircraft for high altitude aerial survey missions.
1926: Surveyor Hugershoff develop among many other devices the aerocartograph which gave the photogrammetrist the ability to perform analog aerotriangulation.
1937: Abrams created Abram School of Aerial Surveying and Photo Interpretation for military training.
1940: Kodak patens the first false-colour infrared film
1950s: Schmid and Brown develop new approaches for camera calibration and bundle adjustment
1957: Helava developed first analytical plotter. He played a critical role in development of digital photogrammetric workstations.
1967: Hobrough developed an automated orthophotographic system utilizing correlation of stereo imager.
1970s: With the widespread development of computers, digital processing comes of age
1990s: Digital soft-copy photogrammetry comes of age
2000s: First modern large-format digital camera gain momentum
