    Re: European projections

    Thank you Marcel and George for your excellent, informative replies to my inquiry.


    If I was to travel to Britain or any of the continental countries I would be honored to share a pint or a glass of refreshment with any of you. Alas, it’s nothing like that.

    It was only an inquiry.

    Since I do quite a bit of long cross country hikes and use excellent projections here in the States I was just curious as to what people in Europe use while doing the same thing.


    Over here we have a choice as to the format of the projections. Most use WGS84 datums but a few still use WGS27 datums. I especially like to use the large scale U.S.G.S. projections in the UTM (Universal Transverse Mercator) coordinate format and the smaller scale projections from the U.S.D.M.S. in the MGRS (Military Grid Reference System) coordinate format. Using these 2 coordinate systems allows a person to more accurately pin point one’s position (a meter or less on a 1:24000 projection) than using the Lat/Lon coordinates.


    Yes George, what you’re explaining is the Grid North. Not the same as true north or magnetic north. When a person corrects or uncorrects a bearing using a grid system one must also compensate for that offset along with the declination (variation) offset.
