Hi Heiko,

Sadly the CRS list is hard-coded in the WMS :-(.  We will make this 
configurable in future.  Perhaps the easiest way to make a particular CRS 
appear in your Capabilities document is to edit the capabilities_xml.jsp or 
capabilities_xml_1_1_1.jsp file and manually add your CRS.  For example, where 
it says:

  <c:forEach var="crsCode" items="${supportedCrsCodes}">
    <CRS>${crsCode}</CRS>
  </c:forEach>

You could add directly underneath this:
   <CRS>myCRS</CRS>

Provided that the CRS code is in the EPSG database, it should work (although a 
few codes like Google's EPSG:3857 are not usable in the current TDS - I think 
Ethan is working on it).

Hope this helps,
Jon

Hi,

the list of CRS codes has been reduced between 4.1 and 4.2 as described 
in 
http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.2/faq.html#wmsLimitedCRS

The sollution described there doesn't work with all WMS-clients, since 
some WMS clients parse the GetCapabilities before they build their 
interface.

What is the simplest 'hack' to get the wanted CRS into the 
GetCapabilities as long as it is not properly configurable? My first 
idea was to add the list of CRS manually to the 
thredds/WEB-INF/jsp/wms/capabilities*.jsp files.

Best regards,

Heiko
