Legends define the meaning of the map's symbols, especially those that are not already intuitive or obvious. [10] In addition, a legend may also serve other purposes, including: organizing the symbols into a structure of layers and importance; educating about the subject matter; or describing how the map symbology was created.

Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]
Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address.
In cartography, a locator map, or just a locator, is typically a simple map used to show the location of a particular geographic region within its larger and presumably more familiar context. Depending on the needs of the cartographer, this type of map can be used on its own or as an inset or addition to a larger map.
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 ...
The game has been described as an educational tool for geography, allowing players to learn and identify various global geographical and cultural characteristics. These include writing systems , architecture , left- and right-hand traffic , flags , vehicle registration plates , landscapes , and flora .
Example of an Alphanumeric board. An alphanumeric grid (also known as atlas grid [1]) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number.
Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS ) and relate them to edges in an existing street graph (network), usually in a sorted ...
