OpenStreetMap and OpenLayers used by White House OpenStreetMap data is used as the basemap for http://www.whitehouse.gov/change/ with the map rendered with OpenLayers. Great achievement!
Funny enough for a GFOSSer, islands are sometimes not treated correctly: see for instance Sicily, Corsica and Sardinia, who do not show a fill. Also Indonesia has a lot of missing fills, and even Canada.
Mhh, I see streets in Sicily, Corsica and Sardinia? OSM coverage isn’t great but it looks like (esp. for Canada) that perhaps removed data to focus on US? Mumble…
