This GA data is the base vector dataset for a 100K scale map NATMAP.  I've
tried using this for navigation, and the accuracy is lacking at a
road/track level scale.  It may be useful for knowing what area you are in,
but rarely for knowing what road you are on.  This is apparent if you
overlay the data with the current OSM data.

It also only contains major roads, and many of these have been more
accurately mapped in OSM already anyway.

Still, it may be useful for things like national park boundaries, and a
first pass at features such as rivers etc in remote areas.

I also think the licence requirement for tracking derivatives and changes
to the terms and conditions of the agreement, while not technically
difficult or onerous, are probably incompatible with CC-SA.
