WMS- pre-rendered maps) - http://geo.irceline.be/rio/wfs (
WFS- the data itself)
These layers are interpolated by means of the RIO-interpolation, based on non-validated measurement data transmitted from the three regional networks.
These layers support the TIME attribute in the GetMap request of the WMS. See a detailed description of this specific implementation here:
http://docs.geoserver.org/latest/en/user/services/wms/time.html
For a PNG of the latest hour BC on a transparent background, this would be sufficient: http://geo.irceline.be/rio/wms?service=WMS&version=1.1.0&request=GetMap&layers=rio:bc_hmean&styles=&bbox=22000.0,20000.0,298000.0,248000.0&width=512&transparent=true&height=422&srs=EPSG:31370&format=image%2Fpng
If you prefer a different projection, adjust srs and bbox
More info on WMS: http://docs.geoserver.org/stable/en/user/services/wms/reference.html
The WFS does not support the TIME attribute. Use e.g cql_filter instead:
http://docs.geoserver.org/latest/user/services/wfs/vendor.html
You can filter for a specific location:
cql_filter=INTERSECTS(the_geom, POINT (161617 170644))or combine with time (or any other attribute, see below):
cql_filter=timestamp='2016-02-15T08:00:00+01:00' AND INTERSECTS(the_geom, POINT (161617 170644))Full example (you will have to change the timestamp - only the last 72 hours are available as hourly mean):
