Displaying single map ?!

Hi there everyone,

I just wantedd to ask a question out of curiosity, on how did this website managed to only show the data of a single country. Do they have their own servers that provide the data, and only downloaded that country’s information to say so ? I don’t know if it’s the right place to ask, as there might be some apis or 3rd party providers around that can help one achieve this, but some guidance will be gratefull ;). And if they don’t use OSM, then can this be achieved with OSM ?

Thank you very much.

PD: I suppose they use some tiles provider also, like mapbox, leaflet api etc. :confused:

Maybe they use an own rendering server (http://wiki.openstreetmap.org/wiki/Rendering),

and as input they use a country extract from geofabrik.de or similar, see http://wiki.openstreetmap.org/wiki/Planet.osm
