package org.geotools.datum
{@linkplain org.geotools.referencing.datum.AbstractDatum Datum} implementation. An explanation for this
package is provided in the {@linkplain org.opengis.referencing.datum OpenGIS® javadoc}.
The remaining discussion on this page is specific to the Geotools implementation.
Extensions to OpenGIS API
Convenience methods were added to the
{@linkplain org.geotools.referencing.datum.DefaultEllipsoid default ellipsoid}
class in order to compute orthodromic distance.

| Java Source File Name | Type | Comment |
| AbstractDatum.java | Class | Specifies the relationship of a coordinate system to the earth, thus creating a
. |
| BursaWolfParameters.java | Class | Parameters for a geographic transformation between two datum. |
| DefaultEllipsoid.java | Class | Geometric figure that can be used to describe the approximate shape of the earth.
In mathematical terms, it is a surface formed by the rotation of an ellipse about
its minor axis. |
| DefaultEngineeringDatum.java | Class | Defines the origin of an engineering coordinate reference system. |
| DefaultGeodeticDatum.java | Class | Defines the location and precise orientation in 3-dimensional space of a defined ellipsoid
(or sphere) that approximates the shape of the earth. |
| DefaultImageDatum.java | Class | Defines the origin of an image coordinate reference system. |
| DefaultPrimeMeridian.java | Class | A prime meridian defines the origin from which longitude values are determined. |
| DefaultTemporalDatum.java | Class | A temporal datum defines the origin of a temporal coordinate reference system. |
| DefaultVerticalDatum.java | Class | A textual description and/or a set of parameters identifying a particular reference level
surface used as a zero-height surface. |
| Spheroid.java | Class | A ellipsoid which is spherical. |
