Hello,

is there a possibility to add support for the CRS with the EPSG-Code EPSG:3068 to GeoServer? I have try to fit the file epsg.properties in the data-directory with the following line, but it doesnt't work.

3068=PROJCS["DHDN / Soldner Berlin",GEOGCS["DHDN",DATUM["Deutsches_Hauptdreiecksnetz",SPHEROID["Bessel 1841",6377397.155,299.1528128,AUTHORITY["EPSG","7004"]],AUTHORITY["EPSG","6314"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4314"]],PROJECTION["Transverse Mercator"],PARAMETER["latitude_of_origin",52.41864827777778],PARAMETER["central_meridian",13.62720366666667],PARAMETER["false_easting",40000],PARAMETER["false_northing",10000],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AUTHORITY["EPSG","3068"]]

I think the parametervalue "Transverse Mercator" is incorrect, but GeoServer doesn't accepts the parametervalue "Soldner", which is specified in PROJ.4.

Best regards

Hi,

I believe that the problem is that Geotools does not support the Soldner projection as you state (i could be wrong). What issue are you seeing when you change the projection? A blank map when you zoom to the relevant area?

Hopefully Martin or Andrea (our referencing experts) will have more useful information for you.

Right, current GeoTools code do not known about "Cassini-Soldner" projection. We would need a volunter for implementing it (usually the task is a single Proj4 C file to port to Java).

Cool,

I have created a jira task for this:

http://jira.codehaus.org/browse/GEOT-1757

Now all we need is a voluneteer... :slight_smile:
