Google latitude is a great tool for sharing your location with others. With the app you can select friends, family, or a team or organization with whom to share your location. Everything is displayed on Google Maps. You can see your friends locations in the app on on the online interface at https://www.google.com/latitude.
Google Latitude also allows you some different privacy features. You can set your location to share at a city level, hide your location, or turn off the background updating at any time. I can see a lot of great ways that a team or organization could utilize this program. Because Google Latitude is universal on all smartphone platforms you can also share your location with Android, Blackberry, Windows Mobile, and Nokia users. Here are some screenshots for iPhone:
