GPS Coordinate conversion

Hi,

I am reading raw NMEA data from a GPS device. My problem is that the
coordinates are in the wrong format.

The coordinates I read are in this format: Lat: 555074,3, Lon: 123413,8

But MapPoint needs them in this format: Lat: 55,84568, Lon: 12,56905

How do I convert? I need to use them in MapPoint

Thanks

http://www.easygps.com is a tool that allows you to convert formats. Not
good for batch updates, but...

You can also use "GPS Utility" for converting coordinates from one
format/datum/grid system to another - see www.gpsu.co.uk.

The "Batch File Converter", also available from that website, can be
used as a GPSU driver so as to convert data in batches of files.

Have you tried "Advanced GPS for Microsoft Map Point"?

Yes I can think so. I tried the program in march, but it crashed on my
computer several times when I hit F6. So I gave it up.

http://franson.com/coordtrans also support batch conversions. I haven't
tried this program though.

Henrik,

Strange, I would have expected the NMEA coordinates to look like this:
..=2E.,5550.743,N,01234.138,E,...
For conversions, see http://home.online.no/~sigurdhu/Deg_formats.htm
and look for
"From an NMEA 0183 sentence (Dm,H) to Degrees decimal-minutes
Hemisphere (D m H)", then look for "From Degrees decimal-minutes (D m)
to decimal-degrees (d)".

I suspect that you have a bad file download, a corrupted GPSU file or
an installation problem. If you send me your dataset file (that caused
the crash) by direct email, I will be able to advise you regarding
this problem.
