public class ProjectionBase
extends Object

ProjectionTest is the base for all accuracy tests, this class doesn't really test anything.

Method Summary

protected void	consistencyTest(Projection toBeTested, double falseNorthing, double falseEasting, javax.vecmath.Point2d naturalOrigin, Unit units, double scale, boolean conformal, boolean equalArea, String name) Helper method to test if the projections have given values, and do not change internally.
protected String	doAccuracyTest(javax.vecmath.Point2d origPoint, javax.vecmath.Point2d referencePoint, javax.vecmath.Point2d forwardEpsilons, Projection projection, GeographicCRS geographicCRS, boolean inverse) Transforms the given coordinates in the sourceCRS to the given targetCRS and checks if they lie within the given epsilon range to the reference point.
protected void	doForwardAndInverse(Projection projection, GeographicCRS geographicCRS, javax.vecmath.Point2d source, javax.vecmath.Point2d target) Do a forward and inverse accuracy test, using the standard epsilon values.

doAccuracyTest

protected String doAccuracyTest(javax.vecmath.Point2d origPoint,
                                javax.vecmath.Point2d referencePoint,
                                javax.vecmath.Point2d forwardEpsilons,
                                Projection projection,
                                GeographicCRS geographicCRS,
                                boolean inverse)
                         throws ProjectionException

Transforms the given coordinates in the sourceCRS to the given targetCRS and checks if they lie within the given epsilon range to the reference point. If successful the transformed will be logged.

Parameters:

origPoint - to transform

referencePoint - to which the result shall be checked.

forwardEpsilons - for each axis

projection - to test.

geographicCRS - geographicCRS of the points

inverse - true if the inverse projection should be tested.

Returns:

the result string.

Throws:

ProjectionException

AssertionError - if one of the axis of the transformed point do not lie within the given epsilon range.

doForwardAndInverse

protected void doForwardAndInverse(Projection projection,
                                   GeographicCRS geographicCRS,
                                   javax.vecmath.Point2d source,
                                   javax.vecmath.Point2d target)
                            throws ProjectionException

Do a forward and inverse accuracy test, using the standard epsilon values.

Parameters:

projection -

geographicCRS -

source -

target -

Throws:

ProjectionException

consistencyTest

protected void consistencyTest(Projection toBeTested,
                               double falseNorthing,
                               double falseEasting,
                               javax.vecmath.Point2d naturalOrigin,

                               double scale,
                               boolean conformal,
                               boolean equalArea,
                               String name)
