Class  Description 

AbstractCS 
The set of coordinate system axes that spans a given coordinate space.

DefaultAffineCS 
A two or threedimensional coordinate system with straight axes that are not necessarily
orthogonal.

DefaultCartesianCS 
A 1, 2, or 3dimensional coordinate system.

DefaultCompoundCS 
A coordinate system made of two or more independent coordinate systems.

DefaultCoordinateSystemAxis 
Definition of a coordinate system axis.

DefaultCylindricalCS 
A threedimensional coordinate system consisting of a polar coordinate
system extended by a straight coordinate axis perpendicular to the plane spanned by the polar
coordinate system.

DefaultEllipsoidalCS 
A two or threedimensional coordinate system in which position is specified by geodetic
latitude, geodetic longitude, and (in the threedimensional case) ellipsoidal height.

DefaultLinearCS 
A onedimensional coordinate system that consists of the points that lie on the single axis
described.

DefaultPolarCS 
A twodimensional coordinate system in which position is specified by the distance from the
origin and the angle between the line from the origin to a point and a reference direction.

DefaultSphericalCS 
A threedimensional coordinate system with one distance measured from the origin and two angular
coordinates.

DefaultTimeCS 
A onedimensional coordinate system containing a single time axis, used to describe the temporal
position of a point in the specified time units from a specified time origin.

DefaultUserDefinedCS 
A two or threedimensional coordinate system that consists of any combination of coordinate axes
not covered by any other Coordinate System type.

DefaultVerticalCS 
A onedimensional coordinate system used to record the heights (or depths) of points.

DirectionAlongMeridian 
Parses axis direction of the kind "South along 90 deg
East".

Geotools provides some convenience methods for fetching specific coordinate
values in standard units. For example the DefaultEllipsoidalCS
class provides a getLongitude
method that returns the longitude value in a given set of coordinates. This convenience method free
the user from the task of finding which axis is for the longitude, and performing unit
conversion.
