Other Uses for GPS <strong>Data</strong><br />

What you can do with GPS data really depends on the software you’re using. While you were<br />

at the website from which you downloaded NMEATime (www.visualgps.net), you might<br />

have also come across software called VisualGPS. VisualGPS comes in two flavors:<br />

VisualGPS: A standard free version (see Figure 10-36).<br />

VisualGPSXP: A full-featured version of VisualGPS (see Figure 10-37). This software<br />

is not free (currently a license costs $25 and a 30-day trial is available).<br />
