That's a cool website! The "National Map Viewer" http://nmviewer.cr.usgs.gov/MultiService/viewer.htm is similar, but doesn't offer elevation information (http://ask.usgs.gov/digidata.html is their "Digital Maps & Data" page, which contains a pile of mapping related links). > I often choose to capture the screen > using "Alt, Print Scrn" then paste the image either directly to a word > document or to Paint first. I use SnagIt, http://www.techsmith.com/products/snagit/features61.asp With SnagIt, for example, you could go to Topozone and choose the large map format (you'll have to scroll your browser window to see the map in its entirety), ask SnagIt to capture the active window (namely, your browser window) using automatic scrolling, and SnagIt will snag all of it, saving the image in the image format of your choice (e.g., gif or png). In general, as soon as you can view on image on your screen, you've already downloaded it, however. For example, I can go to the National Map Viewer website, navigate to the location I'm interested in, then open C:\Documents and Settings\Thomas Fly\Local Settings\Temporary Internet Files (on a Windows XP PC)- for which I have a handy desktop icon- sort by "Last Modified," and there'll be a big fat png file somewhere near the top; I can then drag a copy of it to my desktop. Topozone downloads its maps in pieces, however, so that technique wouldn't be of much value in that case.
