schema/components/crs/1.0.1/crs.schema.json

The coordinate reference system (CRS) component specifies the spatial reference for an object's coordinate data. It supports three representations, exactly one of which must be provided:

• epsg_code — An integer EPSG code (between 1024 and 32767) from the EPSG Geodetic Parameter Dataset.
• ogc_wkt — A WKT2 string representation of the CRS.
• An unspecified CRS (no properties), used when the coordinate reference system is unknown or not applicable.

The CRS defines the order, direction, and meaning of every coordinate axis. Coordinate field labels such as x, y, and z denote the first, second, and third CRS axes — they do not imply easting, northing, and elevation. See Coordinate reference systems and axis order.
