Brandenburg

I have a couple of German Web Map Servers.

State of Brandenburg DOPs:
http://isk.geobasis-bb.de/ows/dnm.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
Administrative boundaries for Brandenburg:
http://isk.geobasis-bb.de/ows/dnmvg.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
Digital Navigation Model, Scale 1:10000:
http://isk.geobasis-bb.de/ows/dnm010.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
Digital Navigation Model, Scale 1:25000:
http://isk.geobasis-bb.de/ows/dnm025.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
Digital Navigation Model, Scale 1:100000:
http://isk.geobasis-bb.de/ows/dnm100.php?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.2.0
Digital Navigation Model, Scale 1:250000:

They use an inofficial EPSG-Code 325833 which is EPSG:25833 with an additional
false easting of 3000 km (which is the official CRS for Brandenburg, ETRS89
with 7 digit rightings). More about these servers can be found here:

These servers have just been moved to a new system two weeks ago.

I also have WMSs for Saxony, including DOPs from the great flood in 2003, but
right now I get 502 Proxy Errors for the whole website of the department of
geography of Saxony.
The saxonian servers have been used by me in uDig. I might add them later on
if anyone wishes them to be included.
