I believe you are attempting to convert the
Gauss-Krueger projection coordinates to Universal
Transverse Mercator projection coordinates. Neither are given in latitude
and longitude. GMT refers to Greenwich Mean Time!
If you want UTM coordinates, what UTM zone do
you want to use? Or put another way what central meridian do you want to
How accurate do the latitude and longitude
values have to be? What datum do you want these values on?
What datum do you want to use for the converted
coordinates? The same datum as used by the GPS satellites - WGS84?
The process is as follows:
1. The Gauss-Krueger projection coordinates will
have to be converted to their appropriate datum.
2. These latitude and longitude values will have to
be transformed from their datum to WGS84.
3. The WGS84 values will have to be converted into
UTM coordinates for the Zone required.
Do you have the datum transformation values to go
from the German datum to WGS84?
Thank goodness the monument/building doesn't move
in all this, just its numerical representation on the earth!

Subject: map co-ordinate assistance
Does anyone know how to translate/transform a
Gauss-Krueger co-ordinate to a GMT mapping of latitude/longitude?
I have spent the past 40 minutes on the Internet
and downloaded two programs but am still at a loss as to how this is done or
how to use the data generated .
The co-ordinates I have are: R_gk :
H_gk : 5538903
I believe they are a location for a monument or building
listed as "Gut Blumenscheid" within 2km of the town of Wittlich,
Thank you for any assistance.
