[OSM-newbies] GPS coordinates

[Markus Lindholm]

I just configured my mobile phone (Nokia N95) to tag photos with GPS
coordinates. I thought this would be a great help in surveying, but I
can't seem to match the GPS values in the EXIF metadata with the GPS
values in JOSM or Potlatch. For example the city hall of Stockholm is
located at N59 19' 39" E18 03' 12" according to a photo taken there
whereas JOSM gives the coordinates as 59.3278 18.0529. How can I
reconcile these two values?
