[Geotools-gt2-users] StreamingRenderer and Gauss Kruger Data

[Thorsten R. <tho...@ig...>]

Hi all,

I have been working with the StreamingRenderer to render a
FeatureCollection with SimpleFeatures. The goal is develop a renderer
which actually renders two different states of the same data in one
panel. You can see the source code for this here:
http://www.esdi-community.eu/repositories/entry/hale/Client/src/eu/esdihumboldt/hale/rcp/views/map/SplitRenderer.java

Basically, everything is working, with the exception that the data gets
rendered a bit strange: rotated by 90° and flipped along the X axis.
Consequently I assumed it might be a problem with the relatively new CRS
that my data uses (EPSG:31251) and it's Axis definitions, so I directly
parsed the WKT for that, using the result for the MapContext given to
the renderer. That did not solve the issue, so I decided to perform a
transformation of the data to WGS84 first before passing to the renderer
again; however, this time the render output even remains empty.

Any ideas what might cause, or even better, solve this issue?

Thanks & Best regards,

Thorsten
