2. Searching for locations

There are a few ways to navigate around the map to find a location.

  • Click the ‘Find me’ button to find your current location. This requires GPS / Location Services to be enabled. A small red dot or arrow indicates your current location.

    More information on location displays.
  • Search using the search box in the top for a town, village, postcode or Grid Ref. In the app, this will only work while you have a data connection.
  • To zoom in, double tap the map. On web you can also use the mouse scroll wheel or the zoom bar in the top right. On the app, you can pinch to zoom.

3. Changing map type

Switch maps with the layer selector button. OS Map types include:

  • Standard: a free, zoomable map, ideal for finding locations and planning on-road activities, particularly in urban areas.
  • OS Leisure Maps: (Premium Feature): Zoom in through our leisure maps including OS Landranger (1:50k) and OS Explorer (1:25k) mapping. The best scale is chosen automatically. In the app, you can choose to lock the map to 1:50k or 1:25k.
  • Aerial: high resolution, zoomable aerial imagery. Great for seeing more detail of the terrain and vegetation, or just to find your house.
  • National Park pathways / Offroad Routing: (Premium Feature): Highlights all paths, tracks, bridleways and roads in National Parks, enabling automatic snap to path route planning.
  • Greenspace: Highlights greenspaces for outdoor recreation.
  • Aerial 3D: (Premium feature, web only): View stunning 3D terrain, with or without your route line. Perfect for showing off how steep that track was!

  1. Click the print button on the toolbar to print your current viewed map, with or without a route.
  2. Choose a fixed map scale, or fit the map to the page if possible. The area to be printed is shown in the overview. Please note that even if you are trying to print an OS Leisure map, the small preview on the screen will show as standard map, but it will still print a leisure map.
  3. Other print options include A4 or A3 size, landscape / portrait and a route card. Once ready, hit the print button.

You must be logged in to print. Some print features, such as A3 printing, and printing OS Leisure map layers are Premium only. There are no printing functions in the app.

6. Using Maps With No Mobile Signal

Use the OS Maps app to download sections of map for use offline. In the app select Menu > My Offline Maps and click ' Add a custom offline map (Menu > Download offline maps on Android).

  1. Find the area you want to download. Click 'Download' to save the area on screen plus about the same in each direction and name it. You can download as many sections as needed.
  2. Click 'Cancel' once you are finished. Please note that once you have hit the download button, hitting the cancel button will not cancel your request, it just takes you back to the previous screen. You can then find your downloaded maps in ‘My Offline Maps’.

If you want to be sure you have all the mapping you need before you lose connection, try turning on 'flight mode' and test.

7. Finding routes

Find great new places by searching our routes list, created by both professionals and other OS Maps users.

On web, select ‘Routes’ > ‘Discover routes’. On the app tap the Routes button or select ‘Menu’ > ‘Find Routes’.

From there, filter the types of routes you would like to find by activity type, distance, duration, or rating.

  • Each pin shows a route start point. Move the map to search the area shown, and use the filters to find a route matching your needs.
  • Once you have selected a route, a preview of the route will appear with important route information on the route card. On the route card you can find such information as the time, distance, elevation, a description of the activity and more. Hit 'Add to favourites' to add it to a list of your favourite routes which is available on app and web.

To stop searching and hide the route pins close the left panel (web) or click the Routes button (app).

8. Plotting routes

  1. On web Select ‘Routes’ > ‘Create Custom Route’. In the app, tap ‘Menu’ > ‘Plot a Route’.

    Click or tap on the map to create a start point, then create your route by adding more points.
  2. Inside National Parks you can use the ‘snap-to-path’ feature to make route plotting quicker. Just select the 'Offroad Routing' layer on the app or 'Leisure' layer (web). When the magnet icon is selected, your route will automatically ‘snap’ to the nearest right of way.
  3. Change the route line colour, thickness, and transparency by selecting the ‘style’ option.

When saving a route, you can choose to make it private or public. If you’re making it public, make sure you give it an informative title and description.

‘My Routes’ shows all your previously saved routes to review or print. (Saved routes are automatically synchronised between browser and app versions.)

‘Import GPX’ allows you to import a GPX route file from your GPS device or other source. More information on GPX files.
