It is possible to use satellite map on openscales, like that http://api.ign.fr/geoportail/api/doc/examples/geoportalFxMap_minimum.html
I'v seen a exemple :
<os:WMSC name="Nasa"
url="http://openscales.org/geoserver/gwc/service/wms"
layers="bluemarble"
format="image/jpeg"
maxExtent="-180,-90,180,90"/>
But it's show just an image of earth and when i zoom in, image lose quality !? Is there any other solution !?
