• GeoJSON and geographic coordinates: longitude first, WGS 84 and the right-hand rule

  RFC 7946 fixes GeoJSON positions as [longitude, latitude, optional elevation] in WGS 84 decimal degrees, wraps geometries in Feature and FeatureCollection objects with a properties member, requires polygon rings to be closed with counterclockwise exteriors, recommends cutting geometries at the antimeridian, and states that the number of digits carries no uncertainty meaning.
