Acme Mapper is great. I can plot points on a topo map and send them in an email or post them on a forum. I love it -- but it was having a problem earlier today.
Just in case, anyone got a good substitute? I'm familiar with G4map which is excellent, but I'm not aware of a way to easily plot points with G4map the way I can with Acme mapper.
Cal Topo looks like it just might be the way to go if Acme is floating belly up in the fish pond. You can in fact generate a web link (URL) such as this one: example route on a USGS topo map.
