Can't draw a perfect circle with gpanot?
I'm trying to draw an arc with gpanot and I get an oval instead of a
circle because the radius is specified in degrees. Of course, 1 degree
of longitude is not the same as 1 degree of latitude, so the farther
North I go, the less circular the arc.
Is there someway to specify the radius in nautical miles? Might there
be a clever way to fix it with projection.
