Changing the World, One Map at a Time

The Ushahidi platform is built on the Kohana web framework, a fork of the CodeIgniter framework. It includes built-in support for Clickatell SMS gateways, and the official Ushahidi-hosted websites use the commercial service. Ushahidi provides the option of using OpenStreetMap maps in its user interface, but requires the Google Maps API for geocoding. Ushahidi is often set up using a local SMS gateway created by a local FrontlineSMS set-up. This video provides a good overview on how the platform is being used around the world.
