A few (late) comments on your idea…
Our experience from the sun trace network experiment is that we received quite a number of results that were obviously wrong. Our instructions apparently have not been clear enough so that people position their smartphone correctly. We threw those away – or we would not have had any result.
We are wondering if you can achieve an appropriate accuracy with both finding north and even the orientation of the magnetic field. As already written, there are some external factors that could affect the local direction of the magnetic field. Moreover, the firmware of the smartphone itself needs to compensate for internal magnetic fields (compare the “standard” readings with the raw sensor data, a switch is in the three dots menu).
(there has been a post in the “Bugs” forum: could you resolve it? The iOS parser is more strict compared to that on Android. The editor should always output correct code, though.
