Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Often called mean sea level (MSL), it is a type of standardized geodetic vertical datum that is used in numerous applications, including surveying, cartography, and navigation. Mean sea level is commonly defined as the midpoint between the mean low and mean high tides at a particular location. [6] sea stack See stack. seabed. Also sea floor or ...
An icon representing the concept of location. In geography, location or place are used to denote a region (point, line, or area) on Earth's surface.The term location generally implies a higher degree of certainty than place, the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry.
The word "orient" is derived from Latin oriens, meaning east. In the Middle Ages many maps, including the T and O maps, were drawn with east at the top (meaning that the direction "up" on the map corresponds to East on the compass). The most common cartographic convention nowadays is that north is at the top of a map.
The exact application of a toponym, its specific language, its pronunciation, and its origins and meaning are all important facts to be recorded during name surveys. Scholars have found that toponyms provide valuable insight into the historical geography of a particular region.
In geography and particularly in geographic information science, a geographic feature or simply feature (also called an object or entity) is a representation of phenomenon that exists at a location in the space and scale of relevance to geography; that is, at or near the surface of Earth.
Location information (known by the many names mentioned here) is stored in a geographic information system (GIS). There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data.
The word aerodrome derives from Ancient Greek ἀήρ (aḗr), air, and δρόμος (drómos), road or course, literally meaning air course.An ancient linguistic parallel is hippodrome (a stadium for horse racing and chariot racing), derived from ἵππος (híppos), horse, and δρόμος (drómos), course.
