Note (3/07/2009) - We've started adding 1:100K and 1:250K scale USGS topographic maps, starting with southern Oregon and moving out from there. Coverage will be a bit sparse at first while we crank up automated processing of map tiles at these topographic map scales. To view 1:100K and 1:250K scale topos, you'll need to manually select them from the sidebar (the Choose Automatically selection will not select these map scales until we have more coverage). You can use the coverage map types to see what areas we've already processed and have online. Also note that satellite photo coverage isn't meant to be particularly useful at this point, it's just (very) experimental.
