Abstract coordinate reference system, usually defined by a coordinate system and a datum.
A coordinate reference system describing the position of points through two or more independent coordinate reference systems.
A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system but is not a projected coordinate reference system.
A contextually local coordinate reference system.
A 3D coordinate reference system with the origin at the approximate centre of mass of the earth.
A coordinate reference system based on an ellipsoidal approximation of the geoid; this provides an accurate representation of the geometry of geographic features for a large portion of the earth's surface.
An engineering coordinate reference system applied to locations in images.
A 2D coordinate reference system used to approximate the shape of the earth on a planar surface.
A 1D coordinate reference system used for the recording of time.
A 1D coordinate reference system used for recording heights or depths.
Uses one of the other EPSG factories backed by a database instead.
AbstractCRS is the base class for all
coordinate reference systems (CRS). CRS can have an arbitrary number of dimensions. Some are two-dimensional
ProjectedCRS), while some others are one-dimensional
TemporalCRS). Those simple coordinate systems can be
used as building blocks for more complex coordinate reference systems. For example, it is possible to construct
a three-dimensional CRS with (latitude, longitude, time) with an aggregation
TemporalCRS. Such aggregations
are built with
