Website for hi-rez USGS maps?

I've been using MapQuest.com for online map exploration, but when I
print them they're quite lo-rez.

Anyone know a free'n'easy online source for good hi-rez online maps?

Thanks.

That terraserver.com is pretty cool. I can see our street. I see they
give examples showing buildings and cars. But I can't zoom in that
much. What's the trick? --JP

No trick. Just zoom in as much as you can. You can make out cars, but any more
detail is probably restricted by the Govt.

Depends on where you a Some parts of the US (afair Dallas-FW, NJ and
a couple of others) allow general access to 30-cm (i.e. one-foot)
resolution images.

FWIW, If you have a good trail map, you can superimpose it on a topo
map. Here's an example:

The topo map came from topozone.com. The trail map came from the county web
site.

Better yet, make your own good trail map from GPS track logs and superimpose it
on a topo map.

See, for example:

Cool. But the question is How? I could do it but it would take me
hours. I'd have to figure out how to do transparent background in
Photoshop. That trick always stumps me. Is there an easy way? --JP

It's easy with practice. It did take a couple hours to put this map
together--something to do in the winter when the weather is not good for
skiing.
Start with a topographic map from topozone.com
Paste the trail map over the topo map
Set the opacity of this new layer to 50%
Pick a landmark near the center of the map to match
Starting with this centerpoint, select sections of the trail map and
stretch or distort them until the landmarks match near the edges. I usually
do this one quarter of the map at a time.
Now you want to remove the background from the trail map. If it is
uniform, this is not hard. Use the magic wand tool to select sections of the
background and cut them.
Reset the opacity of the trail map layer to 100%
Flatten the layers
Save in any file format you like

I like Lew Lasher's GPS track method (in this thread) even better. I
don't have a GPS unit and was unfamiliar with the capabilities.
