Package org.geotoolkit.temporal.object Description

Coordinate reference system definitions as coordinate systems related to the earth through datum. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the SIS implementation.

The root class for this package is AbstractCRS. Coordinate Reference System (CRS) can have various number of dimensions, but some restrictions apply depending on the CRS type:

Common Coordinate Reference System types
Dimension CRS type examples Remarks
3 Geographic, Geocentric ISO 19111 uses the same class, GeodeticCRS, for those two cases.
2 Geographic, Projected GeographicCRS can also be 3D.
1 Vertical, Temporal.
Any Compound Often used for adding a time axis to the above CRS.
Some SIS implementations provide additional methods that are not part of OGC/ISO specifications: In addition Apache SIS provides two distinct classes for geographic and geocentric CRS where OGC/ISO defines a single GeodeticCRS type. OGC/ISO distinguishes the geographic/geocentric cases according the type of the coordinate system associated to that CRS: SIS keeps the geographic and geocentric CRS as distinct types since such distinction is in wide use.
