Hi everybody,
I’m still messing with gps on openmap.
When I convert a GPGLL message (containing DMS coordinates) to decimal
degrees I get a point pretty close to the right one but still wrong, while
if I load the same message into a nmea2kml converter (such as
http://www.h-schmidt.net/NMEA ), I get exactly the right coordinates. So I’m
missing something in the conversion. I’m just converting the dms value (e.g.
5318.56460 -> 53* 18’ 56,46'' -> 53.31568), what else do I need to do to get
the right position?
E.g.
INPUT Nmea message $GPGLL,5318.56460,N,00613.46033,W,110812.000,A,A*48
OUTPUT My app: user position: 53.31568 -6.2294536 (wrong)
OUTPUT Kml converter: <coordinates>-6.22434117,53.30940850,40</coordinates>
(correct)
INPUT Nmea message $GPGLL,5318.56451,N,00613.46047,W,110814.000,A,A*4F
OUTPUT My app: user position: 53.31568 -6.2294574 (wrong)
OUTPUT Kml converter: <coordinates>-6.22434117,53.30940850,40</coordinates>
(correct)
