Subject: Navteq/TeleAtlas data sources

I'm wondering where companies like NavTeq and TeleAtlas get their data for
street/road maps and geocoding.

I've heard that they do their own "fly over" with arial photography, but I
can't imagine how this would provide all the needed information, including
address/location correlation, street/road names, water bodies, parks,
schools, etc., i.e., all the things they put on their maps, as well as the
parcel boundaries and coordinates they use for locating an address.

It seems that they would need need to go around the country county-by-county
gathering all this information, but that would be a very big effort.

Would anyone on this list know where I could learn about this?
