Pattern is the spatial arrangement of objects in the landscape. The objects may be arranged randomly or systematically. They can be natural, as with a drainage pattern of a river, or man-made, as with the squares formed from the United States Public Land Survey System. Typical adjectives used in describing pattern are: random, systematic ...
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method".
Green, 515/520–590/600 nm, is used for imaging vegetation and deep water structures, up to 90 feet (30 m) in clear water. Red, 600/630–680/690 nm, is used for imaging man-made objects, in water up to 30 feet (9 m) deep, soil, and vegetation. Near infrared (NIR), 750–900 nm, is used primarily for imaging vegetation.
This category is for articles about specific, individual, mostly man-made objects (including matching sets). Buildings and bodies of water are not categorized here, nor are other geological, geographic or astronomical features. Classes of objects will be found under their respective collective names.
An object can mediate messages between time or space or both between people who are not together. A work of art, for example, can transfer a message from the creator to the viewer and share an image, a feeling, or an experience. [10] Material can contain memories and mutual experiences across time and influence thoughts and feelings.
The use of radiometric dating was first published in 1907 by Bertram Boltwood [2] and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of Earth itself, and can also be used to date a wide range of natural and man-made materials.
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.
This definition is typically loosely extended to include collisions between sub-orbital or escape-velocity objects with an object in orbit. Prime examples are the anti-satellite weapon tests. There have been no observed collisions between natural satellites, but impact craters may show evidence of such events.
