Do archaeologists use aerial photography?
Aerial photography, the most common type of aerial survey, has revolutionized the archeological community over the past hundred years.
What are the two types of aerial photography used in Archaeology?
Looking at a wide range of photographs (vertical and oblique photographs) from different years will give you a perspective on the changing landscape, condition and preservation of the sites over time.
What is aerial photography GIS?
Aerial photography is the taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically.
What is aerial photography in archaeology?
Aerial reconnaissance is a very effective method of discovering and recording archaeological sites and involves archaeologists flying in a light aircraft, searching for, and photographing archaeological sites and landscapes.
What are some examples of aerial photography?
Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or “drones”), balloons, blimps and dirigibles, rockets, pigeons, kites, parachutes, stand-alone telescoping and vehicle-mounted poles.
What is scale of aerial photography?
Scale is the ratio of the distance between two points on an image to the actual distance between the same two points on the ground. Scale is an important describing factor of vertical aerial photography.
What is aerial exploration?
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Measurements on aerial images are provided by photogrammetric technologies and methods. Aerial surveys can provide information on many things not visible from the ground.
What are types of aerial photography?

How are aerial shots taken?
Normally, air photos are taken vertically from an aircraft using a highly-accurate camera. Other important concepts used in aerial photography are stereoscopic coverage, fiducial marks, focal length, roll and frame numbers, and flight lines and index maps.
What is flying height in aerial photography?
To estimate the AGL, you will need to determine the average elevation of the terrain and subtract that from altitude above sea level. This will give you the average flying height above ground. Example: A camera with a 152 mm focal length takes an aerial photograph from a flying height of 2280m above ground level.
