ProjectionTransform

public ProjectionTransform(ProjectedCRS projectedCRS)

A projectiontransform with an id set to FROM_geoID_TO_projId

Parameters:

projectedCRS - The crs containing a projection.

Method Detail

doTransform

public List<javax.vecmath.Point3d> doTransform(List<javax.vecmath.Point3d> srcPts)

Description copied from class: CRSTransformation

Do a transformation, e.g. the incoming data comes from the sourceCRS and must be transformed to the targetCRS.

Specified by:

doTransform in class CRSTransformation

Parameters:

srcPts - the points which must be transformed, expected are following values either, long_1, lat_1, height_1, long_2, lat_2, height_2. or long_1, lat_1, long_2, lat_2

Returns:

the transformed points

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in class CRSTransformation

Returns:

true if this transformation doesn't transform the incoming points. (e.g. is the id. matrix)

toString

public String toString()

Overrides:

toString in class Identifiable
