OS MapFinder FAQ

Which devices does the app work on?

    OS MapFinder works on the following:

    • iPhone (3GS and later models)
    • iPod Touch
    • iPad 2, iPad 3 – Retina display
    • iPad Mini, iPad Mini 2 and later models

    All devices must be running iOS 5 or above.

      How can I buy a map tile?

      To buy a map tile, select the Purchase mode from the application menu. Once in Purchase mode, press the button on the tile that you wish to buy. OS Landranger Maps are indicated by the pink buttons and OS Explorer Maps are indicated by the orange buttons.

      What is the difference between OS Landranger Map (1:50 000 scale) and OS Explorer Map (1:25 000 scale) map tiles?

      OS Explorer Map is 1:25 000 scale and is the most detailed of Ordnance Survey's leisure maps. It is ideal for walking, hiking and cycling. OS Landranger Map is 1:50 000 scale and shows a larger area, but with less detail.

      OS Explorer Map

      For detailed navigation when walking, hiking, cycling and running, the OS Explorer Map series is ideal. The 1:25 000 scale (4 cm to 1 km, 2½ inches to 1 mile) shows national trails, recreational paths, picnic areas, viewpoints and selected places of interest. In addition, there’s rights of way information for England and Wales.

      OS Landranger Map

      For planning day trips and getting to know an area, OS Landranger Maps are perfect. This 1:50 000 scale, (2 cm to 1 km, 1¼ inches to 1 mile) all purpose map is just what you need if you want to get the most out of your trips covering an area 40 km by 40 km.

      Where can I view the maps I have purchased?

      You can view your purchased maps by pressing the £ Purchase button in Purchase mode.

      Why are some map tiles coloured in the purchase section?

      Tiles are coloured if you have previously bought them.

      • Orange tiles denote OS Explorer Map tiles that you own.
      • Pink tiles denote OS Landranger Map tiles that you own.
      • Green tiles indicate that you own both the OS Explorer Map and OS Landranger Map tiles for that 10km x 10km square.
      How can I download tiles I have bought to my other iPhone or iPad devices?

      Map tiles, once purchased through your iTunes account can be downloaded onto all devices registered to that account (i.e. if you purchase on your iPhone you don't have to repurchase on your iPad). To do this, simply follow the following steps:

      • Step 1: Go to the Purchase section via the menu.
      • Step 2: Tap the £ Purchases button.
      • Step 3: Tap the Sync button.

      Alternatively, if you hit the buy button on a tile and go through the purchase process, Apple knows if you have previously paid for that tile and you won't be charged again.

      • Step 4: Enter your Apple id and password when prompted to sync your purchases.
      Can I use 3G and WiFi to download my maps?

      Yes, you can download maps using either WiFi or your data connection.

      Please note: Each map tile, which represents 10 km x 10 km, can be several megabytes in size, so we strongly recommend that you download data over wifi rather than using your mobile data connection.

      Why is my map not downloading?

      Please check that you have a working Internet connection before downloading a map tile. If you are using 3G rather than wifi, please also ensure that you have a large enough data allowance to complete the download.

      How can I record a route?

      To record a route, press the Record button in the map mode.

      Please note: you must have location services enabled and available. You can enable Location services via the General Device Settings screen.

      How can I plan a route?

      To plan a route, select Menu, then Routes, then press the Plan button in the Routes mode. You do not require location services to plan a route.

      Plan your route by placing points on the map. To place a point, simply tap on the map. While planning your route, you can estimate the duration by selecting different route types. The route types available are ‘walking’, ‘running’, ‘cycling’ and ‘other’.

      How does the application estimate the duration of my planned route?

      For walking, we calculate the time based on a speed of 5 km per hour. We are ignoring the type of terrain and the elevation of the route, so please take this into account the type of walk you are planning and treat the estimate as a rough guide only. We do not currently provide estimates for running or cycling speed.

      How do I add a picture to my route?

      When saving a recorded or planned route you can add a picture from your device gallery or (if available) or take a photo with your device camera. You can edit this picture by selecting the saved route in Routes mode.

      How do I save routes?

      When you record or plan a new route, you will be asked to save that route. You can personalise your routes by adding a name, description and image. You can now share routes and export GPX files in this version of the application.

      How can I import GPX routes' files into my OS MapFinder application?

      You can import GPX route files directly from an email attachment or a web link.

      From a web link:

      • Step 1: Tap on either the GPX file or the GPX URL link you wish to import into OS MapFinder.
      • Step 2: Tap Share in the top right corner of the opened window.
      • Step 3: Tap the OS MapFinder icon.

      From an email attachment:

      • Tap the email containing the GPX attachment
      • Import the GPX attachment by holding down the GPX file in your email.
      • A pop-up window appears, allowing you to select how to open the file
      • Tap the Open in OS MapFinder icon.
      How do I share a route?

      To share a route:

      • Step 1: Select the Routes option from the OS MapFinder menu bar.
      • Step 2: Select the route you which to share.
      • Step 3: Select the Share route option. On iPhone this is a rectangle icon with an arrow, on the top right of the screen.
      • Step 4: Select the service you wish to share to from the sharing menu.

      You can also export a route as a GPX file by selecting Export Route.

      How do I import a route into OS getamap?

      To import a route into OS getamap from OS MapFinder:

      • Step 1: Export the route from OS MapFinder using the Export Route feature.
      • Step 2: This allows you to email the route out of the app. You then access your email on your computer and download it from there.
      • Step 3: Use the Import a Route tool in OS getamap, locate the route you just downloaded from email and click Open
      Why is my location not being picked up?

      Location services allow location-based apps to use information from cellular, WiFi1, and Global Positioning System (GPS)2 networks to determine your approximate location.

      • Please ensure that your location service is turned on: (Settings > Privacy > Location Services).
      • If you are using an iPod Touch or iPad that supports cellular data, please ensure that your WiFi is turned on (Settings > WiFi).

      iOS devices without a mobile data connection use only WiFi for location services (if a WiFi network is available).

      How do I improve my GPS accuracy?

      GPS accuracy varies depending on the number of visible GPS satellites. Locating all visible satellites can take several minutes, with accuracy gradually increasing over time. Use these tips to improve GPS accuracy:

      • Ensure the date, time, and time zone are correctly set on the device in Settings > General > Date & Time. If possible, use Set Automatically. Important: Incorrect settings on your computer can sync to your device. Verify the date, time, and time zone on any computer that syncs with your device.
      • Restart your device.
      • Verify that you have a cellular or WiFi network connection. This allows the Assisted GPS (A-GPS) on the device to locate visible GPS satellites faster, in addition to providing initial location information using the WiFi or cellular networks. Note: Microcells (sometimes called Femtocells) are not supported with location services.
      • Maintain a clear view of the horizon in several directions. Keep in mind that walls, vehicle roofs, tall buildings, mountains, and other obstructions can block line of sight to GPS satellites. When this occurs, your device will automatically use WiFi or cellular networks to determine your position, until the GPS satellites are visible again.

      GPS is available on iPhone and iPad WiFi + 3G models.

      What about crowd-sourced WiFi and cellular location services?

      If location services is on, your device will periodically send the geo-tagged locations of nearby WiFi hotspots and cell towers in an anonymous and encrypted form to Apple, to augment Apple's crowd-sourced database of WiFi hotspot and cell tower locations. In addition, if you are travelling (for example, in a car) and the location services is on, a GPS-enabled iOS device will also periodically send GPS locations and travel speed information in an anonymous and encrypted form to Apple, to be used for building up Apple's crowd-sourced road traffic database. The crowd-sourced location data gathered by Apple does not personally identify you.

      iPad (WiFi + Cellular models): Verify that Cellular Data is on in Settings > Cellular Data, even if you are not subscribed to a cellular data plan. This will allow your device to calibrate itself more accurately using network time and location information. In some instances, disabling a SIM PIN may be necessary.

      Which lat/long projection system is used in OS MapFinder

      WGS84 (World Geodetic System) is used for the latitude and longitude figures displayed on the app.

      Can I throw out all my paper maps now?

      No. We don't recommend that at all. Ordnance Survey recommends that users of this app, and any mapping apps, also carry a paper map with them as a back up when out and about, in case the device runs out of power.

      How do I read a map and what's a grid reference?

      Our Map Reading ebook (PDF) will help you get started. You might also find our explanation of the National Grid useful.

      Do your maps indicate legal rights of way?

      Public rights of way shown on Ordnance Survey 1:25 000 scale mapping have been taken from local authority definitive maps and later amendments. Rights of way are liable to change and may not be clearly defined on the ground. Please check with the relevant local authority for the latest information. Please note that the representation on Ordnance Survey 1: 25 000 scale mapping of any other road, track or path is no evidence of the existence of a right of way.

      The exact nature of public access routes shown on Ordnance Survey 1:25 000 scale mapping and the existence of any restrictions may be checked with the relevant local highway authority. The alignments shown are based on the best information available.
