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 ...

As first implemented the system had 21 regions, 221 subregions, 378 accounting units, and 2,264 cataloging units. [ 1 ] [ 2 ] Over time the system was changed and expanded. [ 3 ] As of 2010 there are six levels in the hierarchy, represented by hydrologic unit codes from 2 to 12 digits long, called regions , subregions, basins , subbasins ...
Topographic isolation and prominence A - Nearest higher neighbour. The topographic isolation of a summit is the minimum horizontal distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point.

[1] They are pedagogical themes that guide how geographic content should be taught in schools. [4]
Attributes, characteristics of a feature other than location, often expressed as text or numbers; for example, the population of a city. [19] In geography, the levels of measurement developed by Stanley Smith Stevens (and further extended by others) is a common system for understanding and using attribute data.
