Hi,
What is GPX?
GPX (the GPS eXchange Format) is a data format for exchanging GPS data between programs, and for sharing
GPS data with other users. Unlike other data files, which can only be understood by the programs that created
them, GPX files actually contain a description of what's inside them, allowing anyone to create a program
that can read the data within.
How can GPX help me?
GPX lets you exchange data with other GPS users, who might not be using the same software as you.
Imagine the following scenario:
You're leaving for vacation tomorrow, and you wonder if anyone has some waypoint data for the tropical
paridise you'll be visiting. You do a quick search on the web, and find a data file created by a GPS user
who just returned from vacation!
You've found some GPS data you can use on your vacation! Perfect! Or is it?
Without GPX
You download the file,
Vacation.txt from the vacation webpage, and try to open it with your GPS
software.
It crashes. Even though your GPS software reads and writes text files, this one is a bit different.
You try making some changes by hand, but
it's taking too long, and you're afraid you'll make mistakes.
You do a quick web search to find a solution, but
no converter exists. You end up printing out
the text file and entering some of the waypoints into your GPS by hand. On the second day of your vacation,
you realize that all the waypoints are
off by a quarter mile. It turns out the website owner had his
GPS set to a different datum, and you
forgot to change your GPS before entering the data by hand.
With GPX
You download the file,
Vacation.gpx from the vacation webpage, and open it with your GPS
software. You're surprised that it
opens and transfers successfully to your GPS, since the file was created
by a Lowrance GPS user on a Macintosh computer using a program you've never heard of. But since your
GPS software supports GPX as well, you now have a
complete, accurate set of waypoints for your vacation.
Feeling lucky, you wonder if there's a way to get the waypoints into your new street
mapping software, so you can plan a route from the hotel. Your street mapping software doesn't support GPX,
but maybe there's a converter available? A quick search on the web turns up another webpage! You wonder how
much it's going to cost to buy a program just to do the conversion, but it turns out you
don't even have to
install new software - the webpage uses a
FREE online form to
convert your GPX file. You
click the Submit button on the form, and your web browser launches your street mapping software with the
converted data.
The next day, lying on the beach, you think about
how easy it is for GPS programs to
exchange data using GPX.
While sipping a cool drink, you remember that anyone can write their own GPX converter to
transform GPS
data into a spreadsheet, a personal webpage, or a data file for their favorite program. And you think to
yourself, "
GPX really is a better way to exchange GPS data."
What are the benefits of GPX?
Here are some of the benefits that GPX provides:
- GPX allows you to exchange data with a growing list of programs for Windows, MacOS, Linux, Palm, and PocketPC.
- GPX can be transformed into other file formats using a simple webpage or converter program.
- GPX is based on the XML standard, so many of the new programs you use (Microsoft Excel, for example) can read GPX files.
- GPX makes it easy for anyone on the web to develop new features which will instantly work with your favorite programs.
