Improve Coordinate System and Map Projection

[erikquinn]

• Replace 2D coordinate system with one primarily driven by latitude/longitude
  • Move all flat x/y operations used in canvas to be generated from getters that take into consideration the below
  • Ensure proper projection when zoomed out to view a very large area, so great circle arcs between two points are always straight. Expected maximum typical zoom level is ~1000 miles.

What we want (see Google Earth / Google Maps Satellite): 👍

Note that the US/Canada border (same latitude) is shown as a curve, and that the great circle arc from point A to point B is straight.

What we have (Mercator Projection, see Google Maps): 👎

Note that the US/Canada border (same latitude) is depicted straight, and that the great circle arc from point A to point B is curved.

Hello erikquinn

For that one, you might find helpful this answer in aviation stack exchange about map projections. Gnomonic projection depicts all great circles as straight lines, so you might want to give it a try.

and thus, all issues are being closed. If this is still an issue with the latest version of the sim
(accessible at http://www.openscope.co), or is a feature you still think we are lacking,
please reopen the issue at the new repo.

Please note that the vast majority of these issues have been copied to the new repository, or else are covered by other issues created there. See the below screenshot for what it looks like when your issue is known in the new repo:
