FIREMIN  GPSBabel has been part of my 'GPS Apps' folder ever since I got a Mac capable GPS. It does what it says: simple conversion of GPS files between formats. Very handy if you need to get data from a proprietary format into one that you can fiddle with, or, for example, convert to kml to view on Google Earth.

The "Babel Fish" of GPS apps : )  
(Version 1.3.7 beta 20090828)

KIRKBOT  GPSBabel works wonders... I've enjoyed using it to visualize waypoints and tracks from my garmin legend c in google earth (with out $ubscribing to google earth plus). GPS babel will allow you grab waypoints tracks and routes off your GPS and save them as .kml (keyhole markup language, works with google earth). Also, will allow you to load waypoints you've added in google earth to your GPS (in googleearth save a marker or folder as a .kml, then import in GPSBabel with output as GPS receiver).

A ton of GPS formats are convertable, easy to use, free, and i've had no stability issues. Enjoy!

Note: When copying to hdd, be sure to include the unix exe and the app (just copy everything over)

ANONYMOUS  I don't see an email address to submit this comment to MacUpdate, but this is GPSBabel (as it says), but not MacGPSBabel which is what would be of interest to readers of this site. The 1.2.6 Mac version doesn't appear to have been released yet, at least it isn't listed on the GPS Babel site. GPSBabel is UNIX, not Mac.

AMAGINE  This is a great start for GPS file conversion on the Mac. Great work thank you!

Probably the most usefull file format for use beyond the "Mickey Mouse" GPS applications for Mac is the 'deliminated (comma)' format for input into text, spreadsheets, database, and GIS (Canvas 9, GRASS, Pythagoras).

To make this app an absolute killer would be:

1. GPS Sample - Produce a sample output from GPS that reads out all information that the GPS is able to output. ie. UTM zone, UTM co-ordinates, Projection, Long/Lat, time/date, Satellite info, waypoint codes, comments, etc. Perhaps depending on the GPS this is hard?

2. From Sample choose the fields and order in which those fields can be output into 'deliminated' format.

This would be huge! It would become the killer app for Rec GPS input into GIS.

Great work crew!

cheers!

MTNBIKER  I'm confused by this posting dated in late August. The last update was May 1, and the last beta was in July.

Also the write-up is way overblown as MacGPSBabel doesn't support two (and there aren't many) Mac program formats--MacGPSPro and HikeTech (TopoDraw/Link2GPS).

Also settings are not retained and have to be reset with each launch and in some cases each download.

The price is good--free. Not top value because for a little money, one can get a lot more funtionality.That said neither HikeTech nor MacGPSPro are very complete programs. i've yet to try National Geographic Topo.
