[ckan-dev] problem with spatial previews

Wed Aug 12 13:42:35 UTC 2015

http://mapserver.lgb-rlp.de/cgi-bin/erdbeben?&request=GetCapabilities&VERSION=1.1.0&SERVICE=WFS

but we have hundreds of wfs in our geoportal ;-)

http://www.geoportal.rlp.de

if you need another link, please ask - ckan 2.4 was able to request the
caps and show the featuretypes as layers in the ol client - only the get
feature request has the problem with the wrong crs
