Ordnance Survey Compass Help

Purpose of this Ordnance Survey Map Compass site
Our OS Map Compass is an Ordnance Survey Maps tool that enables users to plot and record grid references, compass bearings, distances and magnetic declination or variation for single or multiple routes. Users may choose between plotting a single-leg or multi-leg route and the OS Compass then overlays an interactive Silva compass on an Ordnance Survey Map. Users can drag the compass and position it to point in any direction. Users can then plot a route on the map using the compass. The compass tool will automatically adjust for differences between magnetic and true north for any location and also provide users with the latitude and longitude coordinates, grid references and distances of their routes. Ordnance Survey Map Compass routes can be printed or saved and stored for later retrieval.Google Maps have been integrated within this Ordnance Survey Map tool. Google Compass overlays a compass on a Google Map that matches the Ordnance Survey Map location.
Our Ordnance Survey Maps Compass could be used to teach students about the difference between magnetic north and true north. Students can position the compass on various places on the map to see how the difference between magnetic north and true north varies depending upon where you are in the UK.
Our Ordnance Survey Maps Compass application is ideal for educationalists, orienteers, walkers and hikers wishing to practise compass reading and plan routes from the comfort of their classroom or armchair.
