public class DefaultLinearCS

extends AbstractCS

implements org.opengis.referencing.cs.LinearCS

A one-dimensional coordinate system that consists of the points that lie on the single axis described. The associated ordinate is the distance from the specified origin to the point along the axis. Example: usage of the line feature representing a road to describe points on or along that road. A shall have one axis.

Constructor Detail

DefaultLinearCS

public DefaultLinearCS(org.opengis.referencing.cs.LinearCS cs)

Constructs a new coordinate system with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotools one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API. This constructor performs a shallow copy, i.e. the properties are not cloned.

DefaultLinearCS

public DefaultLinearCS(java.lang.String name,
                       org.opengis.referencing.cs.CoordinateSystemAxis axis)

Constructs a coordinate system from a name.

Parameters:

name - The coordinate system name.

axis - The axis.

DefaultLinearCS

public DefaultLinearCS(java.util.Map properties,
                       org.opengis.referencing.cs.CoordinateSystemAxis axis)

Constructs a coordinate system from a set of properties. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

axis - The axis.

Method Detail

distance

public Measure distance(double[] coord1,
                        double[] coord2)
                 throws org.opengis.spatialschema.geometry.MismatchedDimensionException

Computes the distance between two points.

Overrides:

distance in class AbstractCS

Parameters:

coord1 - Coordinates of the first point.

coord2 - Coordinates of the second point.

Returns:

The distance between and .

Throws:

org.opengis.spatialschema.geometry.MismatchedDimensionException - if a coordinate doesn't have the expected dimension.
