Package org.geotools.referencing.cs

Coordinate systems implementation.


Class Summary
AbstractCS The set of coordinate system axes that spans a given coordinate space.
DefaultAffineCS A two- or three-dimensional coordinate system with straight axes that are not necessarily orthogonal.
DefaultCartesianCS A 1-, 2-, or 3-dimensional coordinate system.
DefaultCompoundCS A coordinate system made of two or more independent coordinate systems.
DefaultCoordinateSystemAxis Definition of a coordinate system axis.
DefaultCylindricalCS A three-dimensional 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 three-dimensional coordinate system in which position is specified by geodetic latitude, geodetic longitude, and (in the three-dimensional case) ellipsoidal height.
DefaultLinearCS A one-dimensional coordinate system that consists of the points that lie on the single axis described.
DefaultPolarCS A two-dimensional 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 three-dimensional coordinate system with one distance measured from the origin and two angular coordinates.
DefaultTimeCS A one-dimensional 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 three-dimensional coordinate system that consists of any combination of coordinate axes not covered by any other Coordinate System type.
DefaultVerticalCS A one-dimensional coordinate system used to record the heights (or depths) of points.

Package org.geotools.referencing.cs Description

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.
