Aerial Photography
Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures, it is also known as aerial videography. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloons, blimps and dirigibles, rockets, pigeons, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remotely operated or triggered automatically. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Elevated photography can also produce bird's-eye images closely resembling aerial photography (despite not actually being aerial shots) when ...

Compound (fortification)
In military science, a compound is a type of fortification made up of walls or fences surrounding several buildings in the center of a large piece of land. The walls can either serve the purpose of being tall, thick, and impenetrable, in which case they would be made of wood, stone, or some other like substance; or dangerous to attempt to scale, in which case they could be made of barbed wire or electrified. Compounds can be designed to double as living spaces and military structures in the middle of hostile territory or as a military area within a country's territory; they are also used by those who want to protect against threats to themselves or their property. A number of survivalists own fortified compound-like structures as a means of protection in case civilization breaks down or their government becomes abusive. The term ''compound'' is also used to refer to an unfortified enclosure, especially in Africa and Asia. See compound (enclosure). Specific group usage Insurgent, ...

Palisade
A palisade, sometimes called a stakewall or a paling, is typically a fence or defensive wall made from iron or wooden stakes, or tree trunks, and used as a defensive structure or enclosure. Palisades can form a stockade. Etymology ''Palisade'' derives from ''pale'', from the Latin word ', meaning stake, specifically when used side by side to create a wood defensive wall. Typical construction Typical construction consisted of small or mid-sized tree trunks aligned vertically, with as little free space in between as possible. The trunks were sharpened or pointed at the top, and were driven into the ground and sometimes reinforced with additional construction. The height of a palisade ranged from around a metre to as high as 3–4 m. As a defensive structure, palisades were often used in conjunction with earthworks. Palisades were an excellent option for small forts or other hastily constructed fortifications. Since they were made of wood, they could often be quickly and easil ...

Rampart (fortification)
In fortification architecture, a bank or rampart is a length of embankment or wall forming part of the defensive boundary of a castle, hillfort, settlement or other fortified site. It is usually broad-topped and made of excavated earth and/or masonry.Darvill, Timothy (2008). ''Oxford Concise Dictionary of Archaeology'', 2nd ed., Oxford University Press, Oxford and New York, p. 376. . Early fortifications Many types of early fortification, from prehistory through to the Early Middle Ages, employed earth ramparts usually in combination with external ditches to defend the outer perimeter of a fortified site or settlement. Hillforts, ringforts or "raths" and ringworks all made use of ditch and rampart defences, and they are the characteristic feature of circular ramparts. The ramparts could be reinforced and raised in height by the use of palisades. This type of arrangement was a feature of the motte and bailey castle of northern Europe in the early medieval period.

Fluvial Terrace
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers". These terraces lie parallel to and above the river channel and its floodplain. Because of the manner in which they form, fluvial terraces are underlain by fluvial sediments of highly variable thickness.Fairbridge, R. W., 1968, ''Encyclopedia of Geomorphology.'' Reinhold Book Company, New York.Blum, M., and T.E. Tonqvist, 2000, ''Fluvial responses to climate and sea-level change, a review and look forward.'' Sedimentology. v. 47 suppl. 1, pp. 2-48. River terraces are the remnants of earlier floodplains that existed at a time when either a stream or river was flowing at a higher elevation before its channel downcut to create a new floodplain at a lower elevation.
