In Topo Maps+ you can also export your data into KML and GPX formats. This lets you view your data in other apps like Google Earth. To export your data just tap on “Sharing and Export” in the menu, then “Export Data”, and then select the tags, routes, trips, and waypoints you wan to export.
Once you have selected the data you want to export, select the format (KML or GPX), and then tap on the Export button. You will then be able to email that file or open it in another app that supports that file format.
