Hi Everyone,
I'm one of the developers of the new MakkaMappa iPhone app - it's a (currently) free app that lets you turn any map image into a GPS-enabled map. You can visit makkamappa.com to see more about it.
I don't want to be seen as spamming the forum, but I thought some of you might be interested in it as it is currently free to use.
You can upload any map image to makkamappa.com, calibrate it with our online tool, then download it to your iPhone instantly. One of the best things about the app is that you don't need a data connection to use the maps so it's perfect for when you're out in places with weak phone signal coverage
We currently have a number of ski/snowmobile maps and thought that the app could be used for mountain biking trail maps - see where you are on the actual trail maps rather than just a satellite image.
It's entirely up to you which maps you upload, they can be hand-drawn sketches, or perfect geographically correct maps.
Thanks and I hope some of you have a look at it,
Michael
