Since 2010, Britain's national mapping agency Ordnance Survey has released a large amount of free map data. UK Map makes much of that data available in a single app. It includes 1:1M MiniScale® and 1:250k road maps, which are built into the app, and 1:25k district maps and 1:10k street maps for the entire country which you can download in 5km by 5km tiles. As the free O.S. data does not include footpaths, this app superimposes footpaths derived from volunteer-collected data from These downloads are free of charge.

In addition to the free maps, you can also purchase and download 1:50,000 and 1:25,000 maps that are just like the Ordnance Survey paper maps.

Once you've downloaded the detailed maps that you need, an internet connection is not required.

The app can load GPX files (for example, from websites, other apps and from nearby devices via AirDrop) and display waypoints, tracks and routes. You can also mark waypoints, plan routes and record tracks within the app, and export them.

You can view graphs of altitude or speed along recorded tracks and routes.

The app has a 3D mode that lets you view the terrain from any viewpoint, useful for visualising hills and mountains.

The app also includes a searchable gazetteer containing over 250,000 place names, 850,000 street names and 1.6 million post codes. All of this data is built in to the app, so this search also works when there is no network connection.

The app also supports the compass and GPS - on those devices that have them - to display your position, orientation and altitude.

Paid maps are licensed for personal and non-commercial use only.

A boon for walking tours

I am preparing for my third walking visit to the UK (2013). Last year, UK Maps was a great help in planning my walks into Bodmin Moor and Dartmoor. This year, I'll be finding my way to several fishing streams in Scotland. Once again, this app has been an invaluable assistant for planning (and dreaming). I remember the weight and bulk of the Ordnance Survey maps I had to pack on my trip to Wales in '96, before the days of tablets and smartphones.... All these great maps stored in just one of many travel apps on my iPad which will be tucked into my backpack. It doesn't get any better than this!
