    Map Projection Overview
    =======================
     The Magellan digital gravity maps are presented in a
     simple cylindrical  projection. In this projection,
     parallels of latitude are straight lines with constant
     distances for equal latitude intervals.  Meridians of
     constant longitude are also straight lines with constant
     distances for equal longitude intervals.  The lines of
     latitude and longitude intersect at right angles.  This
     projection is convenient when data are  given at equally
     spaced intervals in latitude and longitude,  as may be the
     case when results are derived from a spherical harmonic
     model.  The projection is also known as the 'equidistant
     cylindrical' projection [SNYDER1987].  Each pair of integers
     ('line' and 'sample') represents the center of a pixel.  The
     corresponding latitude and longitude of a point is in
     rotating fixed body planetocentric coordinates."
