Looking for US land cover data

[Perry]

I'm looking for United States land cover data (wooded, etc.) in vector format.

National Map Seamless Server
http://seamless.usgs.gov/website/seamless/viewer.htm

National Map Seamless Server has National Atlas land cover data listed but when I've tried to download it the only format available appears to be GeoTiff.

I either get "Extracting data...Please wait for the data to be returned"...forever; or I get an error message after clicking the download button.

National Atlas

National Atlas has the land cover data available by state as a Geotiff with the value of each pixel representing a land cover type.  I've been able to download from there, but have not found a way to turn the Geotiff into a vector format file that can be used for Garmin map making.

So I'm looking for either a source of the data already in vector format or a way to convert the Geotiff.

For the seamless server if you get that error clear your cache and then try again.  If it still doesn't work wait a few hours (sometimes it definitely just doesn't work during certain times).

Also, I was having some issues with Firefox 3 and it so I ended up using IE7.

I'm gonna download some land cover and see what I can do to convert it

Well, you're right.  I have no idea how to convert the tif file into a vector file.  Global Mapper can't do it.
