Failure to load a layer from a mapproxy wms/wmts service

[landryb]

Loading http://tiles.craig.fr/ortho/service? in the map viewer as a WMS service it correctly shows the layer tree, but when i try to load a layer from the list, the tree is collapsed and firebug spits an error about a missing extent

I know the map viewer is not meant to be a fullblown websig, just filing issues so i dont lose track of this...

• Ok the first issue is because the capabilities doesn't contain a EX_GeographicBoundingBox tag for the layer. It contains a LatLonBoundingBox instead, but this tag seems not to be managed by ol3 parser.

The code is based on: https://github.com/geonetwork/core-geonetwork/blob/develop/web-ui/src/main/resources/catalog/components/common/ows/OWSService.js#L150

So we should add a test and process the BoundingBox tag instead if empty.

• the second point is because your service is a WMS service so the ol3 WMTS parser just cannot read it.

The service responds both to WMS and WMTS queries on the same URL, it's just that the gfx component doesnt add ?service=WMTS to the url when requesting the getcapabilities.

Using http://tiles.craig.fr/ortho/service?service=WMTS as url allows me to load a WMTS layer from this service. Maybe the service should be automatically added like request=GetCapabilities ?

Yes, i can do that, i did it for WMS. https://github.com/geonetwork/core-geonetwork/blob/develop/web-ui/src/main/resources/catalog/components/common/ows/OWSService.js#L91
