Class GeometryTransform
java.lang.Object
org.apache.sis.internal.feature.jts.GeometryTransform
- Direct Known Subclasses:
GeometryCoordinateTransform
An operation transforming a geometry into another geometry. This class decomposes the geometry into it's
most primitive elements, the
CoordinateSequence
, applies an operation, then rebuilds the geometry.
The operation may change coordinate values (for example a map projection), but not necessarily.
An operation could also be a clipping for example.- Since:
- 1.0
