this is from the GPSvisualizer FAQ:
Q. How can I save my Google Map to my desktop or my own Web site?
A. When GPS Visualizer creates a Google Map, it uses a "Google Maps API key" that is unique to gpsvisualizer.com; files created with that key can only be viewed while they are on this site. However, getting an API key is free, so if you want to put a saved map on your own site, you can sign up for your own key and replace my key with yours in the HTML source. Just edit the line that looks like this:
If you just want to save the map on your computer's hard drive and view it "locally," it seems that this isn't a problem at all with version 2 of the Google Maps API. (In version 1, you had to jump through an extra hoop or two to do so.)
But I don't know what that means...... ;-)
