Hi guys,

For calculating the distance between two points, as done on
restate.ae, what do you guys use?  GeoKit?

Thanks,
Michael

Hey Michael

GeoKit? No, we just use math :)

  def distance_between_points(point1_lat, point1_lng, point2_lat, point2_lng)
    dist = Math.acos( Math.sin(deg_to_rad(point1_lat)) *
Math.sin(deg_to_rad(point2_lat)) + Math.cos(deg_to_rad(point1_lat)) *
Math.cos(deg_to_rad(point2_lat)) * Math.cos(deg_to_rad(point1_lng -
point2_lng)) )
    dist = rad_to_deg(dist);
    km = dist * 69 * 1.61;
  end

Cheers,

Thank you so much Junior! :)
The math makes total sense.. except for the 69 at the end, what's
that?
