About the Maps

Since 2010, Ordnance Survey have released a large amount of their map data under a free licence. The maps that this app uses are based on this data, and this is why the app can offer map downloads free of charge. Note that these are not the same as the paper Landranger® and Explorer® maps.

1:250,000 Road Atlas Maps

These maps are built in to the app and are always available. They are based on the OS MiniScale® and 1:250,000 scale colour raster products.

1:25,000 Detailed Maps

These maps are most suitable for countryside use. They are downloaded in 5km squares. Once they are downloaded they remain on your device until you delete them, so you don't need a network connection. They are based on the OS VectorMap™ District product, with contour lines from OS Terrain 50.

None of the free OS data released so far includes footpaths. Since footpaths are essential for countryside use, this app has superimposed footpaths derived from openstreetmap.org data. These paths have been recorded by volunteers; coverage is not yet complete and varies from place to place.

1:10,000 Detailed Maps

These maps are most suitable for urban use as they show most road names, building outlines and name important public buildings. Like the 1:25,000 maps they are downloaded in 5km squares and remain on your device until you choose to delete them. They are based on the OS Street View® product.
