New page

A Coordinate Reference System (CRS) tells you how to interpret coordinates on a map.

It defines:
* The coordinate system (e.g., latitude/longitude vs. x/y)
* The map projection or datum (how the Earth’s shape is transformed to a flat map)
* The units and axes (degrees, meters, etc.)

So the same numeric coordinates can point to different places depending on the CRS.

Common examples:
* Web Mercator (EPSG:3857): x/y in meters for many web maps and default in the {{software}}.
* WGS 84 (EPSG:4326): longitude/latitude in degrees (used by GPS and [[GeoJSON]]).
