This makes sense from a marketing standpoint. The majority of those using this service are going to be looking for detail in the urban areas. We as cavers are interested in the finest detail in the boondocks or at least in areas where we expect to find caves. We are the minority in this situation and will have to live with it.
Having a large collection of 1 meter DOQ maps (USGS Aerials with each pixel georeferenced with UTM) I can attest that those few counties I've accumulated in Texas take a lot of disk space. Imagine the disk space required the whole United States or whole world!

I knew immediately that he was correct, because I'd looked at metropolitan London versus the English countryside before he wrote his e-mail, and had observed that the city was at higher resolution. A look at the Austin area is interesting, however. The city and close surroundings are at what I presume to be highest resolution. A much larger area surrounding the city is in a middle-grade resolution (and appears to be monochromatic B&W). Outside this larger area resolution drops to a lower grade, color image. So there are at least three levels of resolution utilized in the service. Roger G.
