--------------------------------------
Hi [~karl wright],
Can you review the following supositions:
1) Accuracy in GeoExactCircle is defined as a linear distance, still I guess is
a distance in radians, is that correct?
2) Is correct to represent that error in decimal degrees by using
transformation between radians and degrees?
I checked the value provided in here:
https://en.wikipedia.org/wiki/Decimal_degrees
1m correspond to around 9e-6 decimal degrees with is more or less 1.6e-7
radians. So it looks consistent.
Thanks!

> Hi [~dsmiley],
> The purpose of this ticket is to add a new circle shape (GeoExactCircle) for
> non-spherical planets and therefore remove the method relate from
> Geo3dCircleShape. The patch will include some simplifications on the wrapper
> and some refactoring of the tests.
> I will open shortly a pull request.
