| 6 | | EDIT: It would only work on true-direction projections, but mercator is true-angle only. If recursion is done, it does not travel along great distance circles in most cases where a difference in longitude is involved. So while we can measure ''an'' angle distance between two points using mercator, it is not guaranteed that this is an angle distance on a great circle. Having pulled in "getCenter()" was a mistake, as it traces the mercator angle distance, which is not the shortest angle distance on the ellipsoid/sphere. |
