OS MasterMap

OS MasterMap

What is it?

OS MasterMap Topography Layer® is the most detailed and accurate view of Great Britain's landscape – from roads to fields, to buildings and trees, fences, paths and more. In Parish Online it's part of a 'stack' of base mapping layers that means whenever the map is panned or zoomed, there's always an appropriate base map available.


Where does it come from?

Ordnance Survey


How often is it updated?

Every 6 weeks


What area does it cover?

Great Britain


How might you use it?

This layer is switched on by default in Parish Online and gives you an accurate background map to help you orient yourself on the map. It can also be used to get information on the locations of buildings, field boundaries, paths and infrastructure.
