    • AVG_EARTH_RADIUS

      public static final double AVG_EARTH_RADIUS
      Calculate the distance between two points on the earth using the "haversine" formula. This is also known as the great-circle distance This will produce almost identical result to PostGIS ST_DistanceSphere and ST_Distance(useSpheroid=false)
