You can click on the map above and download it as a PDF file.

This will allow you to embed it onto to your phone for use in areas where there is no internet coverage.

To do this you must first have a PDF reader app installed on your phone, so that you have a library on hand where you can archive the map.

iPhone users will already have iBooks installed on their device. Android, Windows and Blackberry users will need to have downloaded a PDF reader app from their respective app stores.
