Does the GeoJSON spec imply or strongly suggest that PostGIS
geometry type should be used over
Looking at section 3.1.1 I am seeing that
In other words, every point on a line that does not cross the antimeridian between a point (lon0, lat0) and (lon1, lat1) can be calculated as
F(lon, lat) = (lon0 + (lon1 - lon0) * t, lat0 + (lat1 - lat0) * t)
with t being a real number greater than or equal to 0 and smaller than or equal to 1.
This would seem to assume a flat/cartesian coordinate reference system? Otherwise, the points should lie along a great circle arc?
