How to encode coordinate system definitions. Builds on referenceSystems.xsd to encode the data needed to define coordinate
systems, including the specific subtypes of coordinate systems.
This schema encodes the Coordinate System (CS_) package of the extended UML Model for OGC Abstract Specification Topic 2:
Spatial Referencing by Coordinates. That UML model is adapted from ISO 19111 - Spatial referencing by coordinates, as described
in Annex C of Topic 2.
Caution: The CRS package in GML 3.1 and GML 3.1.1 is preliminary, and is expected to undergo some modifications that are
not backward compatible during the development of GML 3.2 (ISO 19136). The GML 3.2 package will implement the model described
in the revised version of ISO 19111.
GML is an OGC Standard.

Element gml:axisDirection
Namespace

Direction of this coordinate system axis (or in the case of Cartesian projected coordinates, the direction of this coordinate
system axis at the origin). Examples: north or south, east or west, up or down. Within any set of coordinate system axes,
only one of each pair of terms can be used. For earth-fixed CRSs, this direction is often approximate and intended to provide
a human interpretable meaning to the axis. When a geodetic datum is used, the precise directions of the axes may therefore
vary slightly from this approximate direction. Note that an EngineeringCRS can include specific descriptions of the directions
of its coordinate system axes. For example, the path of a linear CRS axis can be referenced in another document, such as referencing
a GML feature that references or includes a curve geometry. The codeSpace attribute can reference a source of more information
on a set of standardized directions, or on this direction.

Complex Type gml:CylindricalCSType

Annotations
A three-dimensional coordinate system consisting of a polar coordinate system extended by a straight coordinate axis perpendicular
to the plane spanned by the polar coordinate system. A CylindricalCS shall have three usesAxis associations.
Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it
occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods.
This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.

Identifier of the unit of measure used for this coordinate system axis. The value of this coordinate in a coordinate tuple
shall be recorded using this unit of measure, whenever those coordinates use a coordinate reference system that uses a coordinate
system that uses this axis.
