Also bear in mind that a large geographicly 'accurate' circle is going
to appear egg-shaped to viewers on a Mercator projection.  It's only a
cosmetic issue, whether or not that matters depends on your mystery
application.

The scalebar at the bottom of the map is only accurate for one part of
the map (the bottom, the centre, I'm not sure) because that's how
Mercator maps work. East-West distances are distorted as you travel
south to north (hence the egg-shape circles).   Get a whole-UK map up
and pan north ... watch the scalebar.  Cleverly, it adjusts, but
clearly it can't be  accurate for the whole map nor in both
directions.

The resolution of digital maps and polylines is always limited because
they are painted in pixels, at a "whole world view" a pixel may
represent several km. Again whether that matters depends on the
application.
