    Equations for Mercator projections?
    From: Geoff Kuenning
    Date: 2003 Apr 14, 13:40 -0700

    I have some students who need to be able to convert lat/long into x/y
    coordinates on a Mercator projection.  They know the lat/long of the
    upper-left corner and the scale of the map.  They haven't had any
    success finding equations on the Web.  Does anybody have any pointers?
