The Official Ordnance Survey Channel

Ordnance Survey is Great Britain's national mapping authority, providing geographic data, relied on by government, business and individuals. Ordnance Survey data is relied on by us all. If you call for an ambulance or for police assistance, more often than not it's our data that's used to find you. When there's a gas leak or a burst water main, utility companies are planning their response with mapping from us. We are committed to fostering innovation with our open data initiatives and via the GeoVation community through which we fund new and exciting geography based ventures. We are also known for leisure mapping, such as the OS getamap online service and our OS Explorer Map and OS Landranger Map series.
