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 differ significantly at high tide and low tide, and around which a tidal crest circulates once per tidal period (approximately every 12 hours). The tidal amplitude increases, though not uniformly, with distance ...
In the 1992 Spatial Data Transfer Standard (SDTS), one of the first public standard models of geographic information, an attempt was made to formally distinguish them: an entity as the real-world phenomenon, an object as a representation thereof (e.g. on paper or digital), and a feature as the combination of both entity and representation ...

This title provides Mercator's definition of the word as a description of the creation and form of the whole universe, not simply as a collection of maps. The volume that was published posthumously one year after his death is a wide-ranging text but, as the editions evolved, it became simply a collection of maps and it is in that sense that the ...
The collection differs from a set: all the objects must coexist and have some physical relationship. [2] In other words, it is a portion of the physical universe chosen for analysis. Everything outside the system is known as the environment , which is ignored except for its effects on the system.
