While Lat/Lon (or Lon/Lat) is intuitive, it is not an ideal system for addressing a location on a 2-sphere. It has uneven Longitude width vs Latitude and discontinuities at the poles. I wonder what system we would use if the poles were densely populated.

- dTal 5y agoNothing springs to mind. The problem is that location on any surface is a 2 dimensional parameter. However, two coordinates before any kind of "processing" define location on a plane. All spherical coordinate systems are therefore isomorphic to map projections, where the coordinates are simply a cartesian location on the flat map. And no map projection avoids singularities.
