EPSG:4326 is equivalent to WGS84 which is used by GPS devices. So if you want your image coordinates to match your GPS coordinates as good as possible EPSG:4326 is your obvious choice.
The only problem with EPSG:4326 and any other reference system which are based on longitude / latitude coordinates is that they don't have equal distance between two points. Which is the reason why EPSG:4326 is a bad choice for normal maps where people expect that every distance on the map has the same length. cu andreas 2011/11/7 Josh Doe <[email protected]>: > I've been trying to find the discussion or rationale for why EPSG:4326 > is the projection of choice (or only supported projection?), but > haven't had any luck.
