Freemap for Android


Introduction

OpenTrail is an OSM-based Android app for UK hiking/walking. It is closely associated with the UK walkers' OSM site, Freemap. It shows OSM maps using the Mapsforge library.

Note that the source is available via Github at https://github.com/nickw1/Freemap.

See here for more details.

Current Feature List

Feb 2013

  • show mapsforge generated maps with OSM data (showing rights of way) and OS LandForm PANORAMA contours
  • display annotations as an alert box when you reach their location, useful for instance for displaying path directions at ambiguous places
  • find nearby Freemap walking routes, show them on the map, and "play" the route (instructions will automatically appear on your phone)
  • import data from, and export to, GPX
  • find nearby POIs

Platforms

Android 2.1+. Good performance on an SIII, rather too slow on an HTC Hero so I suspect a typical minimum requirement would be one of the 2.2/2.3 generation of phones released just after the Hero.


What about the augmented reality?

At SOTM EU 2011 and SOTM 2011 I spoke about experiments with augmented reality for walkers. and at one point I was going to add thesefeatures to OpenTrail itself. However I consider the AR very much "researchware" and not fully end-user-orientated just yet - for that reason it's been separated out into its own app, Hikar (see https://github.com/nickw1/Freemap/tree/master/java/hikar).
