[ros-users] Should I write plugins for rqt or rviz?

If you want to build something like the ground station functionality ( http://code.google.com/p/ardupilot-mega/wiki/MPGCS ), I would suggest writing two plugins for RQT: one to visualize GPS data on a map, probably using the Google Maps API to provide satellite imagery, and another to display a roll/pitch/yaw vector as a simulated attitude indicator.

I looked around at what rviz could do, but it didn't seem to do controls and displays like that. I'll take a look at rat too, but mainly I want to visualize the roll/pitch and the GPS data on a map.

Is it recommended that plugins be written for rqt or rviz? And are there any tutorials for doing so, for the upcoming Groovy release?
