Upcoming Meetup

[Ian Dees]

Hi all,

I suggested a date for a Meetup after Thanksgiving: http://www.meetup.com/Openstreetmap/Minneapolis-MN/517272/

This doesn't have to be a mapping party (but it can if you want to bring your laptop). I thought we could get together and talk about OSM and maps and other nerdy things before it got too wintery.

I'm excited to hear from everyone!

Hi everyone!

Consider this a friendly reminder that this coming Wednesday, November 30th at 7:00pm we'll be getting together to talk about OSM and maps.

Thanks to Paul Wickman from Northstar Geographics for helping secure the CoCo Minneapolis office as a location for this event.

There are currently 6 people signed up via Meetup [0]. If we can get that to 10 by tomorrow at lunch I'll pick up some snacks and beverages to serve.

Thanks!

Ian

Hi Peter!

No worries, but keep in mind that the meetup is on Wednesday, not tomorrow.

I'll make sure and keep you in on the loop for future events.

Hi Ian,

I don't think we've met but I wanted to let you know that I'm very
interested in OSM and related projects but I won't be able to attend
tomorrow's meetup. Sending this along to stay in the loop. I am
subscribed to the tcmug list so I suppose I'll get future meeting
announcements.

Thanks for getting this moving!

Peter

I am hoping to make it, but my chances are about 50% right now.

David.

[Brad Neuhauser]

I can't make it, but hopefully one of these times...

BTW, cool to see the two bus route relations in the Transport Map layer!

For those that might be confused about what Brad's talking about here, check this out:

The recently-added transport layer shows two route relations I started working on for the 4 and the 16 (I think). If you're interested in how I put those together let me know and we can talk about it tomorrow.

Hi Ian

Thanks for the great demos last night! You showed a site where
someone has packaged OSM data by metro areas. Can you remind me of
the URL for that site.

Thanks

Len

Sure thing!

That was Mike Migurski's "Metro Extracts" here: http://metro.teczno.com/

You should definitely check out all the other stuff he's working on, though. His blog is here: http://mike.teczno.com/

Again, thanks Ian for organizing the get together and thanks to Paul
for arranging the great meeting space.

Ian, what was the Russian site with the 3D building extrusions?

David.

[David William Bitner]

Ian,

Let me save you some time -- what were all the links that you threw out there :-)

(especially for all of us who couldn't make it)

That was "Komzpa"'s latlon.org site: http://latlon.org/buildings; the big tall tower I was talking about is here: http://latlon.org/buildings?zoom=15&lat=55.82128&lon=37.6108&layers=BT

He has a few other neat renderings on there and is the main developer on a completely browser/JavaScript-based renderer: http://kothic.org/js/

Thanks to Paul for sending me the chunk of his browser history, I have a pretty good list here:

We started off talking about how to edit OSM since a few people hadn't done it before. I showed Potlatch 2 via the "Edit" button on osm.org. Someone asked how you decide what tags to use, so I showed the Map Features wiki page [0] along with the Potlatch 2 tag presets pane.

Someone asked how OSM checks to make sure people aren't damaging the data. Unlike other mapping systems that have a review system (Google MapMaker) or a reputation system (wikimapia), OSM trusts mappers inherently and will accept all changes. Other users are expected to review those changes after they're applied and confront anyone introducing bad data. To that end we have the "History" tab on osm.org, but that's really noisy and not very useful so there's also the OWL viewer [1] which lets you mark areas and receive RSS feeds when changes occur there. ITO World also has a "edits in the last 7 or 31 days" map [9] that is useful for spotting changes.

There was a question about tags and how to know (beyond the aforementioned Map Features wiki page) how to tag features as you map. Someone suggested TagStat [2] or Tagwatch [3] to see what's used "in the wild".

There was interest in seeing who used OSM. Portland's Trimet paid some interns to improve their transit data over the last year and have introduced a trip planner based on OSM [4]. MapQuest uses the data in their Open site [5] as well.

I run a tile server for OSM US [6] that caches some imagery from Minnesota [7]. Ask me how to use those in your favorite editor. On a related note, OpenAerialMap [8] is an index of publically-available aerial imagery of different kinds and dates.

We discussed how we can work as a group to improve the data locally and with the community. I suggested that addressing and road topology are two important pieces, with addressing being the most important (since it affects both routing and geocoding). To that end, there's interest in scraping up some address or parcel information from one of the municipalities and working as a group (in a computer lab of some sort?) to add buildings and apply addresses to those buildings in a quick, concerted effort. We could also participate in the FrontDoor mini-mapping tool that Microsoft is doing for OSM [10]. I know that Hennepin county's parcel data is in there. I'm still waiting for the ability to specify the county so that it makes the most sense for us locally.

Beyond that, there's the TIGER Edited Map [11] that shows where roads in the US haven't been touched since the initial TIGER import in ~2008. Those areas would be perfect for someone to check if they had some time. Updating and realigning TIGER is the best way to fix our topology and routability.

Finally, we showed off OSM Fight [12] where you can compare your edits to another person's.

Thanks for coming everyone! We'll have to schedule another one of these shortly.

Thanks Ian! Sounds like I missed a great night.

[Brad Neuhauser]

Ditto to what Bitner said. 

Regarding data improvement, a couple other QA tools I use from time to time are:

KeepRight - http://keepright.ipax.at/report_map.php?zoom=12&lat=44.95&lon=-93.25
OSM Inspector - http://tools.geofabrik.de/osmi/?view=geometry&lon=-93.25969&lat=44.96572&zoom=11
