ich sammle mit einem GPS Sensor Koordinaten. Diese liegen mir im NMEA Format vor, genauer habe ich die GPMMC und GPGGA Strings.
Diese Koordinaten möchte ich jetzt in 2D darstellen.
Könnte mir jemand mit dem Umrechnung helfen?
Da wird die Projektion auf einer Karte berechnet. Ich will aber einfach GPS Punkte in einem Koordinatensystem abbilden, ohne dass eine Karte drüber gelegt wird.http://de.wikipedia.org/wiki/Mercator-Projektion

Beim Umwandeln von GPGGA
NMEA-Daten
bitte in Bogenmaß umwandeln, d.h Altgrad durch 180 mal Pi
z.B.
47°35,5634 = 47,592723 -> 0,8306497 im Bogenmaß
dito für die Länge.
Das kannst Du jetzt mit einem Faktor malnehmen, z.B. dem Erdradius 6371 km.
Oder mit Deiner Schuhgröße.
