Lidar has many applications in the field of archaeology including aiding in the planning of field campaigns, mapping features beneath forest canopy, [7] and providing an overview of broad, continuous features that may be indistinguishable on the ground. Lidar can also provide archaeologists with the ability to create high-resolution digital ...
Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Ground penetrating radar is a tool used in archaeological field surveys. In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and ...
First developed in the 1960s and 1970s, [citation needed] ALB is a "light detection and ranging (LiDAR) technique that uses visible, ultraviolet, and near infrared light to optically remote sense a contour target through both an active and passive system." What this means is that airborne laser bathymetry also uses light outside the visible ...
LIDAR can be used to detect ground surface changes. [10] Vegetation remote sensing is a principal application of LIDAR. [11] Radiometers and photometers are the most common instrument in use, collecting reflected and emitted radiation in a wide range of frequencies. The most common are visible and infrared sensors, followed by microwave, gamma ...
In the early 1980s a group of researchers interested in the history of Iram used NASA remote sensing satellites, ground penetrating radar, Landsat program data and images taken from the Space Shuttle Challenger as well as SPOT data to identify old camel train routes and points where they converged.
Aerial archaeology is the study of archaeological sites from the air. It is a method of archaeological investigation that uses aerial photography, remote sensing, and other techniques to identify, record, and interpret archaeological features and sites. [1]
Yet the imagery is crisp and looks like an optical image. This has been cited as akin to using a telescope in Los Angeles that is the size of the human eye's lens to image a car in New York. Of course, the trick here is that the asteroid is presented among a very sparse background, allowing for substantial disambiguation.
