Method Detail

transform

public static Envelope transform(Envelope envelope,
                                 MathTransform transform)
                          throws TransformException

Transforms the envelope using the specified math transform. Note that this method can not handle the case where the envelope contains the North or South pole, or when it cross the ±180� longitude, because math transforms do not carry suffisient informations. For a more robust envelope transformation, use ReferencedEnvelope.transform(CoordinateReferenceSystem, boolean) instead.

Parameters:

envelope - The envelope to transform.

transform - The transform to use.

Returns:

The transformed Envelope

Throws:

TransformException - if at least one coordinate can't be transformed.

transform

public static Envelope transform(Envelope sourceEnvelope,
                                 Envelope targetEnvelope,
                                 MathTransform transform,
                                 int npoints)
                          throws TransformException

Transforms the densified envelope using the specified math transform. The envelope is densified (extra points put around the outside edge) to provide a better new envelope for high deformed situations.

If an optional target envelope is provided, this envelope will be expanded with the transformation result. It will not be nullified before the expansion.

Note that this method can not handle the case where the envelope contains the North or South pole, or when it cross the ±180� longitude, because math transforms do not carry suffisient informations. For a more robust envelope transformation, use ReferencedEnvelope.transform(CoordinateReferenceSystem, boolean, int) instead.

Parameters:

sourceEnvelope - The envelope to transform.

targetEnvelope - An envelope to expand with the transformation result, or null for returning an new envelope.

transform - The transform to use.

npoints - Densification of each side of the rectangle.

Returns:

targetEnvelope if it was non-null, or a new envelope otherwise. In all case, the returned envelope fully contains the transformed envelope.

Throws:

TransformException - if a coordinate can't be transformed.

                                  throws TransformException

Computes the orthodromic distance between two points. This method:

1. Transforms both points to geographic coordinates (latitude,longitude).
2. Computes the orthodromic distance between the two points using ellipsoidal calculations.

The real work is performed by GeodeticCalculator. This convenience method simply manages a pool of pre-defined geodetic calculators for the given coordinate reference system in order to avoid repetitive object creation. If a large amount of orthodromic distances need to be computed, direct use of GeodeticCalculator provides better performance than this convenience method.

Parameters:

p1 - First point

p2 - Second point

crs - Reference system the two points are in.

Returns:

Orthodromic distance between the two points, in meters.

Throws:

TransformException - if the coordinates can't be transformed from the specified CRS to a geographic CRS.

Parameters:

geometry - the instance of a Geometry to remove collinear vertices from.

minPoints - perform removal of collinear points if num of vertices exceeds minPoints.

Returns:

a new instance of the provided Geometry without collinear vertices.

makeValid

public static List<Polygon> makeValid(Polygon polygon,
                                      boolean removeHoles)

Given a potentially invalid polygon it rebuilds it as a list of valid polygons, eventually removing the holes

Parameters:

polygon -

Returns:

toRectangle2D

public static Rectangle2D toRectangle2D(Envelope envelope)

Converts a JTS Envelope into an equivalent Rectangle2D

Parameters:

envelope - The source envelope

toEnvelope

public static Envelope toEnvelope(Rectangle2D rectangle)

Converts a AWT Rectangle2D into a JTS Envelope

Parameters:

rectangle - The source rectangle

toPolygon

public static Polygon toPolygon(Polygon polygon)

Converts a AWT polygon into a JTS one (unlike toGeometry which always returns lines instead)

Returns:

toPolygon

public static Polygon toPolygon(Rectangle rectangle)

Converts a AWT rectangle into a JTS one (unlike toGeometry which always returns lines instead)

Returns:

toPolygon

public static Polygon toPolygon(Rectangle2D rectangle)

Converts a AWT rectangle into a JTS one (unlike toGeometry which always returns lines instead)

Returns:
