wsgs_wms can be accessed via TAP handle: http://saada.unistra.fr/taphandle/?url=http://epn1.epn-vespa.jacobs-university.de/tap#

granule_uid is the name of the map, granule_gid is the system name, obs_id is  the name of the instrument, target name is the name of the satellite.

access_url points to the service (but does not have a query), eg: http://planetarymaps.usgs.gov/cgi-bin/mapserv?map=/maps/jupiter/jupiter_simp_cyl.map&
 

If you try to open it in the browser, it will give an error.  you need to add a query string to it (intended to be supplied by the client), eg:

 &service=WMS&version=1.3.0&request=GetMap&LAYERS=CASSINI&CRS=EPSG:4326&BBOX=-90,-180,90,360&FORMAT=image/jpeg&WIDTH=540&HEIGHT=180

  where LAYERS=obs_id  (in this example "CASSINI")

  you can change BBOX, WIDTH, and HEIGHT values on the client to pan and zoom on the WMS

GAVO to GIS

 we need a mechanism to connect QGIS to VO HUB, after that, GAVO simply needs to send XML-RPC call to QGIS with the contents of the field access_url.


  You can try it now with QGIS and do it manually. First copy the contents of the "access_url", eg
http://planetarymaps.usgs.gov/cgi-bin/mapserv?map=/maps/jupiter/jupiter_simp_cyl.map&
Then open QGIS, click on add WMS layer:

Click create, give it a name, and paste the link you got from "access_url" into the address field:

Click connect, select the layer and click "Add"

You should now have this layer in QGIS as a WMS basemap:
