The New York Times has a nice article on maps and amateur map makers. The specter of 'citizen journalist' was brought in, but that was easy enough to brush aside.

One point of disagreement I had with the Times article is that we aren't becoming mapmakers. What we are doing, except for those participating in GPS tracing, is map annotating, and I do think that's the interesting part of the story. The only thing needed to bring together this messy new world Atlas, is a global agreement about the structure of the data used to annotate the maps, as well as agreement on the format for retrieving such.

Google provides Keyhole Markup Language (KLM), and the Open Geospatial Consortium provides Geography Markup Language (GML), which actually requires a EULA before you can even read the spec. I also read about a geoRSS, but I'm waiting for geoAtom.

Correction

geoRSS is also geoAtom and geoRDF, but going by the generic 'RSS' label. I guess Sam was right, and RSS is the new Kleenex.

In addition to conferences related to Blogher, Ajax, and OSCON (is this official Summer Conference Week, or something?), there was also a conference on the "Geoweb", held in Vancouver. From that I found an accompanying weblog that most recently discusses a RESTful interface to Geospatial information, and points to a Google Group's discussion on same. People in comments mention "the book" so I'm assuming it's Sam Ruby and Leonard Richardson's, RESTful Web Services.

I'm going to get all Creative Commonsly on you and state that we focus so much on art, music, and creative writing when it comes to the 'be free' movement, when I think we should spend more time on data, specifically metadata. I'm a believer that any service that collects metadata from the public, should make such metadata freely available. I won't use a service that doesn't.

From what I can see, most mapping services do provide this. All but Microsoft. Based on searches, there is no metadata export feature for Microsoft's community-derived map collection.

It's really the metadata that makes the geoweb exciting, and the idea of somehow bringing all those annotations together. There's even chit-chat about GML, RDF, and mutual roots.

Frankly, this is the type of stuff that puts a foolish grin on my face.

(PS, I can recommend the O'Reilly book, Mapping Hacks. I'm using it to figure out how to get the most out of my Garmin eTrex Vista Cx.)

There already is an Atom implementation of geoRSS - http://georss.org/atom

Geo-Atom? Many people are doing it (I'm mashing GeoRSS feeds into Atom at http://zcologia.com/news/523/mush-2-feeds/) and some of us on the Geo-Web-REST group are taking a hard look at whether APP can't replace our industry's crufty old protocols. The "GeoWeb" conference, BTW, is actually dedicated to "big" web services.

GeoRSS is a generic term, and encapsulates atom as well as RSS. Examples here:

OpenStreetMap is actual amateur mapmaking. Some of it is done using GPS traces, some direct from traditional map providers (government and private), some from tracing Yahoo's satellite and aerial imagery (which doesn't inherit copyright).

Thanks for notes on Atom, all, and links to OpenStreetMap, James.

Sean, reminds me of lowercase semantic web as compared to Semantic Web. Any recommendations on where to look for 'small' geoweb resources?

Shelley, i think the best resources are

http://groups.google.com/group/geo-web-rest (Geo, REST)
http://georss.org (but don't fall for the GML encoding!)
http://lists.burri.to/mailman/listinfo/geowanking (blue sky thinking)
http://highearthorbit.com/ (GeoRSS)
http://cfis.savagexi.com/ (Atom, Geo, REST)
http://zcologia.com/news/ (Atom, Geo, REST)

We've come a long way in the last few years, but we are a long way from where we want to be. We want to be to navigate to a point on the globe and be able to type in a search term and have everyone's annotations that are nearby pop up - then we can add our own. Also the time dimension is still missing - a lot of my interests relates to change over time. Google is a long way away from being able to cover all that for just its own "customers" from Maps, GE, Picasa, Keyhole, and Panoramio let alone those comming from Micorsoft, Yahoo etc. I think you want to start with what end users want to be able to do and share collectively and work backwards to what kind of initiative will get competitors like Google and Microsoft (etc) cooperating to make it happen. The problems are in the politics of the industry - not in the choice of a markup language.

Sorry, Seth, I can't resist.

I wasn't aware that "we" wanted to do this. *I* am still waiting for the day that I can view the contents of everyone's refrigerator online.

Or was I mistaking that as the "grand we" instead of "we who are actively interested in this topic"?

lol, ethan — i guess i just assumed that everyone was a mapping buff like me.

Actually, I kind of want to see the contents of everyone's refrigerator.

Seth, I hear what you're saying on being able to input a location and get back the info.

I'd like to see this used for trails. My trail books describe a trail as an easy jaunt, but when I get there, no such thing. I'd like to be able to see trail points mapped and with photos attached. That way I can see for myself if the trail is beyond my capability.

12

Yeah, and color-coding every yard or so along the path for the grade would be nice (photos can be misleading, especially if they don't show the ground).

Hmm… GPS does have a vertical component…

OpenTrailMap!

[…] by this, I added support for this to this. It's in the extensions […]

Just to be fair, Microsoft does export "Collections" as GeoRSS

http://virtualearth.spaces.live.com/blog/cns!2BBC66E99FDCDB98!8495.entry
in section "Subscribe to a Collection via RSS."

[…] Maps n' Data Mentions KML, GML, and 'the geoWeb'… also geoRSS, but is waiting for geoAtom. […]
