converting nmea to gpx

by Raymond Nijssen :: Rate this Message:

| View Threaded | Show Only this Message

I'm trying to convert an nmea file to gpx format using:

gpsbabel -i nmea -f merged.txt -o gpx -F merged.gpx
(or
gpsbabel -t -i nmea -f merged.txt -o gpx -F merged.gpx)

The result (for both commands identical) is a valid gpx file. My input
file contains locations for every 10 seconds though, while my output
only contains track points for every hour. The first point in the gpx
equals the first in my nmea data, afterwards my gpx file seems to
contain the first timestamp after every whole hour:

For example: 12:57:42, 13:00:02, 14:00:02, 15:00:02, ...

I'm looking for a way to tell gpsbabel to convert all my locations, or
convert a location every n seconds or something.

Can anybody help?

I'm using GPSBabel Version 1.4.2 on Ubuntu 11.10 64.

Thanks in advance,

Raymond

Craig,

Sorry, I cannot share the data. It's for a customer and should be kept secret.

But I can create some new data this afternoon and mail it to you.

Thanks,
Raymond

Hello Raymond,

Can you tell me what your project it. I have experience with the GT31, and calculating speeds, and creating maps of routes, etc.

Can you send me a sample file;  and I will process, and send back to you.

Thank you,

Craig Bergh
Worthington, Minnesota
