Different types of north


Google Maps North

Google Maps use a variant of the Mercator projection for its map images. The Mercator map was designed as an aid to navigators since straight lines on the Mercator projection are loxodromes or rhumb lines – representing lines of constant compass bearing – perfect for ‘true’ direction.

True North on Google Maps is not shown, but for a normal Mercator projection, grid north and true north will coincide and it will follow any vertical line (or meridian) to the top of the map.
