Patrick,

The latter. The gdprof routine gdpdta.f calls dgcxtp.f
and will get the lat/lon and real value row/colum of the gpoint (eg
not limited to integer i,j locations), which in turn is
used in the call to $GEMPAK/source/gemlib/gr/grintp.f which
performs a bilinear interpolation from the grid point values to the
gpoint location.
