Description
Class Summary  
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. 
Coordinate systems implementation. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the Geotools implementation.
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.
