With InstaMapper, the object you track is a moving dot on a map. Positions are updated as often as every 5 seconds.

We will store up to 100,000 positions per device -- enough for several months of 24/7 tracking.

Stored data can be exported in KML and CSV formats and accessed programmatically via an API.

By default, your InstaMapper account is protected by a password. Should you choose to share your location with others, we offer several options:

- Send a link to a map with your location.

- Embed a map on a web page or blog.

- Embed a map with your current location in your Facebook profile.

Historical data can be organized into tracks, which can then be exported in a variety of formats and shared with others as embedded maps.

Your InstaMapper account can be accessed from most mobile phones. Point your phone's browser to While you are out of coverage, up to 100 positions can be buffered in phone's memory so that your track doesn't get interrupted. Will learn more here

Using TrailGuru to track outdoor activities on iPhone

TrailGuru is a terrific program for those who get fit with iPhone, it lets you capture your next run, ride, walk, hike, biking trip, or any outdoor activity using your iPhone 3G’s integrated GPS. There are plenty of options for not just runners, which many of the other apps have unfortunately limited themselves too. Besides, you can actually upload all of your stats to a community site to share what you've accomplished and routes you've taken.

The main screen of the TrailGuru shows track of how far you've gone, how long you've been going, and your coordinates (latitude and longitude). All of these data seem to be very accurate as long as you're in an area where you have full cell phone service. Once you complete your trail all you need to do is name it and select how you conquered that trail.

It will exit you out into Safari to do so as well. When you're on your trail, if you receive a phone call or lose reception, the app basically falls apart and stops tracking the information accurately. Even on EDGE it does seem to struggle at doing it's task. So unless you're a big fan of taking a trail located around a 3G tower, you may not find this app too useful.

TrailGuru gives you a chance to differentiate what method of trailblazing you decided to use. This is great for keeping notes and of course reading through others in your area too, so that you can find the best possible trail in your area.

You have first to sign up with them and get your account, and then you are ready to go.

Many customers do not give a good review about TrailGuru, however, you may want to give it a try, or stick with your current tracking software.
