Preliminary Testers Wanted - GPS Tracker

**Tred** · 11-09-2004, 10:14 PM

looks good. can this also log the GPS coordinates? Also im sure many people want to have this running while they are running their norml GPS soft., is there an easy way to set up com port sharing?

will it work with a delorme earthmate gps?

My app is doing the relatively simple part, it is capturing the GPS data and writing it out to a file. The graphical part is all done using other services, the one above was generated at www.gpsvisualizer.com but I am aiming to use www.motionbased.com

You can read and decide your preference but the latter is focussed on sports and tracking lap times and what they call "dot racing" where you race your own tracktime. They basically provide a cool interface and mapping of GPS data, primarilly captured from a handheld GPS (Garmin, Magellan etc).

COM Port splitting - do a search, there are a few ways, COMFoolery is one that comes to mind.

Delorme - yes, should work just fine, as far as I know.

I'm trying to sort out some formatting issues in the GPX XML file at the moment, seems motionbased.com doesn't like my files!

These tracks are based on a sample file but give a good idea on where I'd like this to end up, if everything works out. This is the same track displayed in three different ways at www.gpsvisualizer.com

That's awesome, did you create the track with my app or another GPS? I ask because I realized last night I was tracking longitude a little off and needed a tweak to make it negative!

What did you capture your track with?

Hi, I'm the author of GPS Visualizer. Often, speeds don't plot properly from GPX files that were created by early versions of programs because the people who create the programs don't realize that the GPX specification calls for the speed to be represented in meters per second (and elevation should, of course, be in meters).

So, ukchris: m/s, please!

Whoa, just the guy we need here, thanks Adam!

At the moment I have my results loading into your app pretty well, albeit with the units a little messed up but I can fix that later. The GPX spec is sending me a little nutty with another service though where it rejects my GPX files as invalid, they offer a similar service (www.motionbased.com) but specialize in comparing tracks and displaying graphical data linked to the track at the same time for reference.

Great job on GPS Visualizer by the way!

Chris.

Update, just posted a new exe at www.lawlai.com/mp3car/GPSTracker.zip

Only two minor changes, the speed should be in m/s now so it should represent okay at GPSVisualizer, also it is inserting a "-" before the Longitude which I needed for East Coast US. I need to sort out when it needs to be negative and when it doesn't and fix this properly.
