My first thought is that as well at lat/long, you are going to do need the date of the compass reading to successfully convert them to true north. You are going to need a function like true_north = function adjustBearing(compass,lat, lon, date). This is not a simple function. I would be interested to see if someone has created such a thing that could be used with geotools.

I'm writing a program reading a file and creating graphical objects. I have a starting point (lat/lon WGS 84), a length (m) and a magnetic bearing (degrees). I would like to automatically convert the magnetic bearing to a true bearing when they occurs in the file I'm reading. Is there a converter in geotools that can be used, or is there another way my program can get the declamation?
