What can I do with GPS?

[esraymuk]

I'm a bit new at these things, so forgive my niavity. I understand what GPS is, but I don't understand what I'm able to do on my phone with GPS - does the quickGPS app somehow link into other apps that can make use of GPS? What are these other apps and where do I find them? Does googlemaps make use of GPS?

First and most importantly (imho) is gps navigation.

Think TomTom, Garmin, etc. Being able to use your phone for navigation is nice..and yes, google maps uses your gps, which is awesome. It is slightly off though, like a couple of meters. (So you can't use it as a golf-buddy)

Also, for those who drive their cars on tracks, the possibility of being able to time yourself on the track is nice, not to mention potentially having a map of the track, with logging capability. I would love to be able to analyze results and find out which line was truly faster on which corner. Yeah there are already products that do this, possibly superior to anything the Diamond could do, but since I already have the phone...even if it was .005 seconds off I'd be happy.

Also, geotagging photos. (like..take a photo and it would automatically add the location.)

There are many other reasons...but gps navigation I think is the best.

Geotagging photos would be very interesting, any software for this? Similarly, any free GPS navigation software? (or any non-free software)?

You can geotag Diamond-made photos by its internal software (they actually get geotagged in the moment you make them) with a tweak. To geotag photos made by another camera, you need software which saves GPS data on PPC (aka trace, track, NMEA data) and a program which matches photos to location saved by Diamond.

And GPS nav software you got in 1st reply. TomTom, Garmin, AutoMapa etc. are commercial GPS programs. Google Maps can be free (not sure of that), but since they get maps via Net, they make you pay for data transmission. Most commercial programs work offline.
