Interface TransformRequest

All Superinterfaces:

OGCWebServiceRequest

All Known Implementing Classes:

TransformRequest_Impl

public interface TransformRequest

extends OGCWebServiceRequest

The transform-schema describes the only mandatory request, which is to adapt from the Transformation-Web-Service

The basic elememts of the reqest are the coordinate-system of the data (SourceCRS), the coordinate-system in which the data should be transformed (DestinationCRS) and the data itself. Additional to this the format of the incoming data and the results are declared.

The determination of a transformation-sequence is optional. Normally several single-transformations are needed for the transformation of coordinates from one system into another. With the <TransformationSequence>- element it is possible to define (a) in which order (b) which transformations should be executed.

It is to notice, that the transformationservice is based on the OpenGIS implemantation specification "Coordinate Transformation Service 1.0.0". I. e. that the transformation of a geometry results from the transformation of its particular coordinates. Splines and other not-linear interpolations get not explicit transformed. So, for the the incoming data only point-geometries and linear interpolated geometries are acceptable. In addition to the GML-coded geometries a coding of "Well Known Text" (WKT) is possible. A WKT-geometry is transported as a string.
