I am looking for the base layers for whole U.S. - roads, hydrological lines etc with flexibilities of changing symbology and labels.

TIGER is a good source but it is at county level. I am running on a short deadline right now, so want a quick fix. Can anyone suggest good source where I can find one layer for whole country? Or merged TIGER Census shapefiles for the whole US?

Do you specifically want merged TIGER data, or are you just looking for nationwide datasets from any source? –  RyanDalton Feb 21 '13 at 22:50
    
It's not as accurate or up to date as Tiger, but try nationalatlas.gov/atlasftp.html for nationwide datasets of roads, streams, etc. –  Dan C Feb 21 '13 at 22:53
    
Looking for nationwide accurate datasets. –  Deep Feb 22 '13 at 14:42
    
Please be more specific about what you are looking for. –  underdark Feb 22 '13 at 15:46
    
base layers (cities boundaries, roads, rails, waterbodies and hydrological lines) to display at the background of actual data (points), but with flexible symbology –  Deep Feb 22 '13 at 17:32

What about Esri's Data and Maps for ArcGIS? It is free for licensed ArcGIS users and has national data at many scales.

The data comes with pre-defined symbology for quick use, but the symbols can be changed.

Nice for arcgis users, but not a great resource for the rest of us –  chrismarx Mar 22 at 22:03

Have you looked at Natural Earth? The large scale data includes boundaries, populated places, urban areas, hydro, roads, rails, etc. http://www.naturalearthdata.com/downloads/

I would try RITA, USDOT. They will even send a free DVD of data. https://1bts.rita.dot.gov/pdc/user/products/src/products.xml?p=33304

If I am not wrong, RITA is providing only PDF and HTML map. I am looking for some ESRI supported format. –  Deep Feb 22 '13 at 18:19
    
Nope, they have the US water, states, roads, sundry in shapefile –  lewis Feb 22 '13 at 20:08

The US Census has several files of different resolutions of just the state boundaries, for free here -
