I've explored this world coverage index map a bit more, and the image for
Mexico when you select the "terrain" function is pretty cool. It renders the
terrain attractively, and if you look closely at the closest three levels of
magnification, you will see that topographic contours at 20- and 200-meter
intervals appear on the artistic rendering.

Subject: [Texascavers] Re: Public domain free USGS News rmaps
This is nice to know, but a little late to be really necessary.
Unlike those of many countries, U. S. topo maps have never been copyrighted and
are available in the public domain, but the USGS itself did not host them on
the web. Most states have some agency or university that has USGS topo maps
for specific areas freely available on their web sites. For instance Texas
topos are available at <http://www.tnris.state.tx.us/datadownload/download.jsp>
and New Mexico at <http://sar.lanl.gov/topo_maps/>. Recently, however, the
USGS themselves finally put up all of their maps, so there is no longer a need
for any outside hosts. Go to <http://seamless.usgs.gov/index.php>. If only
Mexico would do the same!
