Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
As in other languages, the word is formed from the fact that east is the direction where the Sun rises: east comes from Middle English est, from Old English ēast, which itself comes from the Proto-Germanic *aus-to-or *austra-"east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", [1] cognate with Old High German ...
For example, assume A and B in the northern hemisphere have the same latitude, and at A the direction to B is east-northeast. Then going from A to B, one arrives at B with the direction east-southeast, and conversely, the direction at B of A is west-northwest. Latitude circles near the North Pole are shown in red.
For example, a bearing might be described as "(from) south, (turn) thirty degrees (toward the) east" (the words in brackets are usually omitted), abbreviated "S30°E", which is the bearing 30 degrees in the eastward direction from south, i.e. the bearing 150 degrees clockwise from north.
A local coordinate system is set up with the x axis horizontally due east, the y axis horizontally due north and the z axis vertically upwards. The rotation vector, velocity of movement and Coriolis acceleration expressed in this local coordinate system [listing components in the order east (e), north (n) and upward (u)] are: [34]
Data East was founded on April 20, 1976, by Tokai University alumnus Tetsuo Fukuda. [1] [6] Data East developed and released in July 1977 its first arcade game Jack Lot, a medal game based on Blackjack for business use. [7] [8] This was followed in January 1978 by Super Break which was its first actual video game. More than 15 arcade games were ...
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
Some say the name is a mispronunciation of "DeWitt's Corner", while others believe the town was due west on a pioneer trail. [6] The Treaty of Dewitt's Corner, a historic peace negotiation in May 1777 with the Cherokee Indians, was signed in Due West. [7] As a result of the treaty, the Cherokee peoples broke into two factions.
