atlaszkoordinátarendszer

An atlaszkoordinátarendszer, often translated as atlas coordinate system, is a system used in cartography and geographical information science to define the location of points on a specific map or atlas. Unlike a global coordinate system like latitude and longitude which refers to the entire Earth, an atlas coordinate system is tailored to the projection and boundaries of a particular map sheet or atlas.

The fundamental components of an atlaszkoordinátarendszer typically include an origin point, an x-axis, and a y-axis. The origin is a designated reference point on the map, often a corner or a prominent feature. The x-axis usually runs horizontally across the map, and the y-axis runs vertically. Positions are then expressed as distances along these axes from the origin.

The specific units of measurement for these distances can vary depending on the atlas or map. They might be in meters, kilometers, inches, or other conventional units. In some cases, the atlas coordinate system might be derived from or directly related to a larger geodetic datum or projection, but its primary function is to provide a localized referencing method within the confines of the atlas itself. This makes it practical for users to locate features within that specific map without needing to understand the complexities of global geographical coordinates.
