If prj2epsg.org does not find the srs it likely means the above does not have an official EPSG code assigned (at least not in version 7.5). I looked in the ESRI database too, can't find a transerse mercator whose central meridian in 78.25 either, it seems like a custom projection? I fear you will have to make up your own code and add it to epsg.properties: http://docs.geoserver.org/stable/en/user/advanced/crshandling/customcrs.html Cheers Andrea -- ------------------------------------------------------- Ing.
