>* 24k scale USGS DRG's - detailed topographic maps for all 50

>* SVG boundary border files for all US states (including state,

>* TIGER/Line - All 2003 data is available.
>* GeoNames - All USGS place names are available for searching. The
>data can be used to find appropriate DRG's.
>
>The site has a handy gazetteer that allows you to search for a name
>(Verde River) or term (dam) and get a list of quad maps from the

>
>Select the quad map you want from the list the site provides, and then

>NOTE: If you're curious, both sites pull the actual quad map Tiffs and
