Tile use

  Tiles from Opensnowmap.org comes in two flavours: one with the relief (hillshade and contour lines), and one with ski pistes only. You are welcome to use the pistes-only tiles (without relief) on your website, but it is madantory to :

• use a valid referer
• prohibit bulk download from your app
• credit Data (c) www.openstreetmap.org & contributors ODBL and www.opensnowmap.org CC-BY-SA.

The base topo map or the piste+relief overlay are too demanding in server ressources to be shared easily.
