GeoBlogs

In a comments thread” to Peterme’s post on regional blogs, Dan Lyke suggested a geo-linked hiking blog: “a big collaborative map that’d have information that no single map publisher can put out right now”

Right now I’m carrying a GPS along when I go hiking or biking, then downloading the track points. My thought initially was that it’d just be nice to have enough GPS data that I can say “I took a photo close to there” and start to attach latitude/longitude information to my photo database.
But I’m doing this with Un*x through various cool but non “user friendly” means, if I can find easy ways for more people to do and set up some sort of application to annotate and manage these tracks a little better, then we could also start to build a big collaborative map that’d have information that no single map publisher can put out right now, and with data of which a good bit of which probably doesn’t exist in digital form.

I wonder if the GeoURL is part of the solution. This is a service that creates meta tags for geographical co-ordinates. I wonder how they specify location, and whether it would be precise enough to locate waterfalls?
GeoURL is Slashdotted right now, so I can’t tell.
The conversational thread has continued on Dan’s site.
