# Gauss Krueger Grid for Germany
# 
# The first figure of the easting is lon_0 devided by 3
# ( 2 for 6d0E, 3 for 9d0E, 4 for 12d0E)
# For translations you have to remove this first figure
# and convert northings and eastings from km to meter .
# The other way round, devide by 1000 and add the figure.
# I made 3 entrys for the officially used grids in Germany
# 
#
# Und nochmal in deutsch :
# Die erste Ziffer des Rechtswerts beschreibt den Hauptmeridian
# und ist dessen Gradzahl geteilt durch 3.
# Zum Umrechnen in Grad muss daher die erste Ziffer des Rechtswertes
# entfernt werden und evt. von km auf Metern umgerechnet werden.
# Zur Umrechnung in Gauss Krueger Koordinaten entsprechend die
# Ziffer fuer den Hauptmeridian vor dem Rechtswert ergaenzen.
# Ich hab fuer alle drei in Deutschland ueblichen Hauptmeridiane
# jeweils einen Eintrag ergaenzt.
