If you're looking for elevation data, the USGS provides this for free for the US.

Example: http://gisdata.usgs.gov/xmlwebservices2/elevation_service.as...

Also worth noting, Adam Schneider's GPS Visualiser website is excellent for quick elevation lookups globally.

Handy for me as Geoscience Australia (another good resource) unfortunately charge for their DEM data.
