I have two sets of coordinates: one from a sphere and the other WGS-84. I’d like to get them both into Leaflet. But Leaflet assumes long/lat points are WGS. As far as I can tell, its quite difficult to convert spherical coordinates to the WGS ellipsoid. However, converting the WGS coordinates to spherical seems pretty straightforward. My application does need to be super accurate so the error should be acceptable. I can’t find a setting to tell leaflet about the underlying geometry. Is that setting available?
