• Zoom in for OS Landranger (1:50,000) and OS Explorer (1:25,000) mapping
• When zoomed in, try the excellent "Bird's Eye View", or inside the M25, "London Street Map"
• Ordnance Survey (OS) mapping is available for mainland GB, and (OS Landranger only) the Isle of Man.
• For Northern Ireland, the Channel Islands, or (Southern) Ireland, try Open Cycle Map (Outdoor Layer). Set maps to Google then select OCM from the list of 'layers'.
• "Portrait" and "Landscape" modes are disabled as printing is against the T&C's for Bing's OS mapping
