How to convert GPS files for Google Earth


I know this will probably get moved, but I've been getting a lot of "how do I do this" emails.


Download THIS FREE Program here (Download GTM Free) in the left column

There is a tool where you select your destination file - the .usr file and selct the output as "google earth .kml" file... click the convert button and it instantly converts it for you.

This will work for MOST GPS file systems and will cross convert any of them to any of the others!

The results are often times NOT perfect, but it saves HOURS of work.

Good luck!
(hey mods, please leave this up for a day so people see it at least... thanks!)

Speaking of "how to" questions, I found your link here and on MORE's race talk on the Google Earth race course for the ORAF 500:

I down loaded the Google Earth program and then tried the link. I was prompted to select the program to open the link with and I selected Google Earth. It appears like it wants to open, but then crashes.:( How about a basic "how to" on the Google Earth program?


Edit: Thanks for the link DesertGuy1, I figured it out.

I don't want to be "that guy" but I need some techno help. I'm trying to convert files from this page
to files that can be uploaded to Lowrance in a .usr file.
I use the Backcounty Adventures books by Massey all the time but have been manually typing in all the waypoints (converting from 100's to 60's in each input) and found the site above that has all the files. But it's in .rxf format. I've tried Ozi, Babel, G7towin and I can't figure out how to use any of them. I got off the technology train at DVD's, I have an Ipod but my teenager has to load music for me. That's my techno level.

Nevermind, I might have figured out Babel if it works. I will have to get home and see if the file will upload to .usr.

GPS Visualizer and GPS Babel work great. Play around with em and youll figure it out.

Now how do you draw a route using Google Maps, then open in Google earth and convert to usr for Lowrance? Babel won't transfer all the data, GSP Vis only does the opposite way. My file has both draw on roads and placemarks in google maps/earth. I haven't played with GTM listed above yet but it was complicated the first time I looked at it.

If anything this is for my future reference as I got if figured out.

From Backcountry Adventures.
• Choose route, right click, file save as .rxf
• OpenGPSBabel
• Input file: Maptech exchange format (.mxf)
• Output file: lowrance (.usr)
Converting from .usr to google earth.
• Go to GPS Trackmaker
• Open .usr file
• Save as .kml file
• Open .kml file in google earth
Converting from google maps to lowrance
• Will convert only trails, not placemarks
• Make route in google maps.
• Click view in google earth
• Save as a .kml file
• Go to google earth and open file.
• Should be open in temporary places.
• Right click and save as .kml file
• Go to GPS Trackmaker
• Open file from .kml
o Note: click merge file to open more tracks.
o Delete excess trails (stray lines) here so they don’t end up on the .usr file
• Save file as .usr

OK...a little help needed:confused: Downloaded the free GTM but when I try to open the Lowrance .usr file to save as a Google Earth .kml file I get the following error:

'Current version doesn't support this file! Please, download the new version of GTM.'

I find no 'new version'. Anybody else having the same issue?

If not, can somebody please convert the file if I send it to them?


I downloaded MXF video Converter free trial version last week, and I converted many MXF videos for playing on QuickTime. This software is good at converting any HD MXF, MTS, TOD, MP4 to MOV videos. With this perfect MXF to AVI converter software, you can convert MXF to H.264 MOV for QuickTime, convert MXF to AIC MOV for editing in iMovie, mxf files converter to ProRes MOV for FCP X importing.
