The orienteering association in Paraguay used to have an excellent page listing all map symbols in Spanish. Does anybody know if it still exists? I used to bring this page up when I taught orienteering to school groups that had Hispanic students with poor English skills, but its been at least a couple years since I used it. I tried linking from IOF and it appears that Paraguay is no longer an IOF member. I tried a couple google searches but couldn't get a hit either. (Katie, I will look to see if I have a printout, but I remember that the one I had cut off one edge, so I'd always just bring the page up on a screen when I was teaching)
A suggestion to David and Katie: go to
www.orienteering.org (International Orienteering Fed). Click on "IOF" at the upper left and you'll get a world map and list of federations. Look for links to any of the Spanish speaking federations and you should find some pages that will help with orienteering-specific terminology.
Here is one for Argentina:
http://www.adorargentina.org.ar/ You should be able to find others (Spain, other Sputh American countries) on your own.
