GeoChat

GeoChat is a flexible open source group communications tool that helps team members keep close track of each other. GeoChat encourages a shared awareness of who is doing what where – and it does it over any device, on any platform, and over any network. GeoChat allows you and your team to stay in touch with one another through whatever method you have available: over SMS, over email, and on the surface of a map in a web browser.
Whether you are sitting at a computer with a high-speed Internet connection, or on the go with nothing but your mobile phone, GeoChat helps you react to events quickly by making it easy to link up your team within moments, and even to form virtual teams on the fly! GeoChat lets you link headquarters to staff in the field, and field staff to each other, and lets you instantly add to your group anyone, from any organization, you think should be there.
GeoChat keeps everyone on the team connected, in sync and aware.


Where do the GeoChat numbers work currently?

NOTE: we are planning to cover as many wireless providers as possible, directly and through partners, but it takes time…

What can I do with Geochat?

With Geochat you will be able to:
  • Create, join and participate in chat groups by SMS, email, or web browser.
  • Add your location in many different location formats, geochat will translate this location into a position in the map.
  • Subscribe a group to one or more RSS/ATOM feeds, and each new item will be broadcast to mobile users via SMS.
  • Create your own “local gateway” mini-client that allows you to plug a local cell phone into your laptop, connect to the Internet, and allow users to send and receive text messages through the service via the local cell network.
  • See, at a glance in the Map, who said what, when, and where.
  • Verify, refute, or update information live from the field using your mobile phone.
  • Share the benefits of their geospatial “big picture” view (if you are a highly-connected user) and push out relevant RSS/ATOMfeeds to a barely connected users via SMS.
  • Ensure that your teammates know where you are and what you are doing.
  • Visualize your remote team on the surface of a map and interact with them.
  • Use it on any PC, Mac, or Linux PC capable of running Mozilla Firefox
  • Use it from any cell phone capable of sending and receiving SMS messages.
