M_RANGE_RING Creates range rings on a map
M_RANGE_RING(LONG,LAT,RANGE) creates a range ring of range RANGE
km centered at the position specified by LONG and LAT. Range rings
will generally appear as small (almost) circles for short ranges,
but will be distorted at longer ranges.
If RANGE is a vector, concentric rings at the specified ranges
are drawn. If LONG,LAT are vectors, rings are drawn around
all specified locations.
The appearance of lines can be modified using the usual
line properties thus:
M_RANGE_RING(LONG,LAT,RANGE, <line property/value pairs>)
Sometimes you may need to adjust the number of points plotted
in each range ring (this can happen if the ring is at the extreme
edge of certian projections). THis can be done using
M_RANGE_RING(LONG,LAT,RANGE,NPTS, <line property/value pairs>)
NB: Earth radius is assumed to 6378.137km (WGS-84 value), and
calculations are for spherical geometry.
