    Subject: RE: [emergency] Re: Circle and Polygon


    We agreed early on in CAP to stick to one global coordinate reference
    system to remove all chance of mis-communication. I think this was/is
    the right thing to do. NATO and most military coalitions that need to
    interoperate have settled on this method. There have been many deadly
    mistakes caused by a misunderstanding of CRSs.
    
    If there is a requirement to use different reference systems I suggest
    they be -in addition to - Or - it be very apparent that a non-standard
    CRS is being used. Users should not be able to get to the coordinates
    without knowing what CRS is being used.
