The root class in this package is
Various subclasses are defined for various kinds of mathematical rules that determine
how coordinates are associated to quantities such as angles and distances.
Those SIS subclasses provide additional methods that are not part of OGC/ISO specifications:
CoordinateSystemsutility class with static methods for estimating an angle between two axes, determining the change of axis directions and units between two coordinate systems, or filtering axes.

ClassDescriptionThe set of coordinate system axes that spans a given coordinate space.High-level characteristics about the axes of a coordinate system.Modifications to apply on the axes of a coordinate system in order to produce a new coordinate system.Utility methods working on
CoordinateSystemobjects and their axes.A 2- or 3-dimensional coordinate system with straight axes that are not necessarily orthogonal.A 2- or 3-dimensional Cartesian coordinate system made of straight orthogonal axes.A coordinate system made of two or more independent coordinate systems.Coordinate system axis name, direction, unit and range of values.A 3-dimensional coordinate system made of a polar coordinate system extended by a straight perpendicular axis.A 2- or 3-dimensional coordinate system for geodetic latitude and longitude, optionally with ellipsoidal height.A 1-dimensional coordinate system for points that lie on a single axis (not necessarily a straight line).A 1-dimensional coordinate system for parametric values or functions.A 2-dimensional coordinate system for coordinates represented by a distance from the origin and an angle from a fixed direction.A 3-dimensional coordinate system with one distance measured from the origin and two angular coordinates.A 1-dimensional coordinate system for time elapsed in the specified time units from a specified time origin.A 2- or 3-dimensional coordinate system for any combination of coordinate axes not covered by other CS types.A 1-dimensional coordinate system for heights or depths of points.
