Mobile Trail Explorer

Biking trip to Hervanta's back forest Ever since I bought the first GPS unit I wanted to be able to record my biking trips and other activities so that I could explore them afterwards on my computer. I couldn’t stop myself from coding this app when I finally acquired Nokia N80 that supported both Bluetooth connections (JSR 82) forreading GPS locations and File connection (JSR 75) for storing recorded trails on a memory card.

The hard part was to get the bluetooth connection to work properly. After I upgraded the firware on my N80 to latest version (v4.0623.0.41) I was able to connect and communicate with the bluetooth device without problems. I’m using the Nokia LD-3W as a GPS unit and it works quite well for my needs.

Currently the application can display current location as latitude and longitude and it can draw a current trail. User can store interesting locations as waypoints that are also drawn on the same canvas. Here is a screenshot from my Nokia N80 and the same trail exported to Google Earth. As you can see the main trail view is very clean and simple :)

Please leave a comment if you are able to try it out on any other phone models. I haven’t tried how the main screen works with devices with lower resolution, like older Series 60 phones.
