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

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.
