A subset of the planetary science community uses and develops GIS for scientific research and exploration of the planets and small bodies of our Solar System.
The OpenPlanetary initiative (http://openplanetary.github.io) wants to experiment with the idea of using a specific tag for all planetary scientists and developers to share knowledge within, and benefit from this Geographic Information Systems StackExchange community.
This tag may also be used across other existing StackExchange communities (eg.: astronomy, space exploration).
Do you think it's a good idea?
