[Freegis-list] Free high-quality country and administrative boundaries

[Tomasz Wegrzanowski]

What is the best *free* data in the following categories ?
I'm listing the best thing I've found so far.

* coastlines
	GSHHS
* topography
	GTOPO30, should I check GLOBE G.O.O.D.?
* bathymetry
	ETOPO2
* satellite images
	BlueMarble
* names of places
	GEOnet Names Server data
* rivers, lakes (the two need to be consistent, so I probably shouldn't use GSHHS for lakes)
	CIA WDB2
* political and administrative boundaries
	CIA WDB2 (ouch - needs something much better)
* roads, railways etc.
	hardly anything found
* ...
	anything interesting I missed ?
