I uploaded 2 pictures of the original
(http://geoserver.itc.nl:8080/wps/original.png) and the resulting merged
lines (http://geoserver.itc.nl:8080/wps/mergedLines.png).
I am not sure, what you mean by testcase. I could post a WPS request and
the URL to the process and you could play around with it. Is it that,
what you mean?
Thanks for your efforts.
