I created a SIG for applications of geographic information systems technology to robotics. This replaces the Geographic Info project on kforge.ros.org.

 http://ros.org/wiki/sig/GeographicInfo

Topics include: satellite navigation systems like GPS, cartography, geodesy and geographic coordinate transformations.

We mainly focus on defining common interfaces and best practices, so various classes of drivers and applications work consistently with other ROS components. Please join if you are interested and wish to contribute.
