Map data is a complete OSM planet import - 20gb compressed file, expanded/indexed into a 225gb database. OSM has lots of good data but most custom styled maps leave out a good amount of it, or, in the case of the OSM style maps, they include way too much.

Importing and indexing planet.osm takes a while. It's better than importing the whole planet file in gazetteer mode for geocoding though. I have been fighting that import for a month now, on decent hardware!
