Got the immediate area around the Bluebell Fire burning near Brook Forest (Evergreen), Colorado pretty well mapped. Also sounds like firefighters have a good feeling they'll get this one contained quickly.
Added public parks areas maintained by the City of Paducah, KY
Have completed the Bronx local bus routes and non-revenue turnarounds, where applicable.
As always, I will review the edits to fill in any gaps I may have left and welcome any corrections or edits deemed necessary.
Will continue to find Tri-State area projects on the transport side (e.g. Westchester Bee-Line and Nassau County (i.e. NICE) buses) as available.
Got the Belleview station road access sorted. Google now a few months out of date
when I am try to edit map using edit with ID map is complete black so I can't edit this map .so how i can edit map
I just mapped Warden Hilltop Community Centre. It has a “green roof” — part of the roof has growing turf, and a trail through it (which would explain how I managed to put a gps trail through the building ☺). How would I tag it?
Green roofs are kind of a thing (and not just 'cos I briefly worked for Green Roofs for Healthy Cities). I can think of some:
For over a year now, since arriving in Southampton to study Computer Science at the University, I have been also working on improving OpenStreetMap. I forget how it I found out about the project, but initialy, I set about mapping in detail my hall of residence at Wessex Lane.
After that, I moved on to improving Highfield Campus, if I remember correctly, the first thing I did was to add all the missing buildings. I also began mapping in detail the residential areas that I frequently walked through when traveling to and from campus.
I also set about adding all the missing building outlines to the city centre, and surrounding areas. Currently, a large part of the middle of Southampton is mapped in some detail. Most of the buildings are present, and some of the buildings have the address information. A good way to look at this is using the ITO World map
Over the summer, I hope to add address information to the most of the buildings that I have added, that are currently missing it. Hopeully I will be able to join up the areas that I am mapping in the centre, with the excellent work going on to the west in Shirley
I have been playing with osmosis/postGIS this week. I was finally was able to import the MA OSM extract today using osmosis.
It took a lot longer than using osm2pgsql and I was very surprised at how large it got when it was imported.
massachusetts-latest.osm.pbf - 205 Megabytes massachusetts-latest.osm - 5 Gigabytes - 25 time (it is an XML file) PostGIS snapshot db - 10 Gigabytes - ???
It looks like PostGIS/osmosis is not noticing that we repeat the same tags, over and over, and over again in the data.
Trying to connect to OSM Route Manager. It seems to be down, with just a dribble of data coming in - one packet every 10s. Is it down, or is it supposed to be like this.

We've managed to get a wonderful venue for the SOTM Baltics!
The conference will be held in the main building of the University of Tartu: http://sotm-baltics.org/location.html
The conference hall is normally used for PhD defence and University Senate meetings. The University of Tartu was found in 1632, its main building was built more than 200 years ago.
Register before the 9th of June for just 10 Euro: http://sotm-baltics.org/register.html
The Call for Papers will be announced in a few days.
State of the Map Baltics conference will be held this year on the 3-4 of August in Tartu, Estonia. For the first time ever mappers, developers and users of OpenStreetMap from Baltic States, Russia, Finland and Sweden will come together to exchange knowledge, strenghten local communities and break the language barrier. Mappers from other countries are also welcomed!
I've made a video. Check it out ...but be warned. It's kind of dull, until 6 minutes 22 second in, when the mapping goes TURBO!
The sped up mapping effect is quite fun. I might have to try that again some time. But the idea of the video was to show how (or at least give a rough idea of how) we go about adding in the data, because we did the usual mapping party thing with beginners, of only demonstrating collection of data. ...I'm talking about at the Marble Arch Mapping Party two weeks ago.
Contributing to OpenStreetMap (usually/always for me) comes in two very different stages: Collecting data, and Inputting data. This is a challenge when it comes to teaching new people, because you don't get a good understanding of what data to collect until you've delved into the OpenStreetMap data using an editor. Unfortunately the cart comes before the horse at a typical mapping party. In fact worse, the cart is left without a horse. We don't usually have the benefit of a computer room or somewhere sensible to bring out laptops and have a serious editing session, and in the event of having lots of new folks to teach, we're left only teaching them half the process. Obviously if no new folks turn up then this doesn't matter. But this was not the case two weeks ago...
As I described previously, I was making a conscious effort to do something a bit different and a bit more welcoming to newcomers for this event. Meeting under the arch of Marble Arch, I was worried I'd be there on my own, but no! Thanks to all the usual OSM faces who decided to make the effort to be there in case they could help (or maybe in case something really exciting was going to happen). Some unusual faces too. Wasn't expecting to see RichardF. ...And some new faces! which was the point of the exercise. We did OK at attracting new folks. If we include the new folks who were jet-lagged and went straight to the pub (disgraceful!) and other new folks who only caught up at the end... we had quite a few!
Our concerted effort to attract new folks was inspired by an academic paper which analysed OpenStreetMap London meet-ups and concluded that we were bad at attracting (and retaining) them. This paper popped up out of nowhere, written by some people we had never met, as I described previously. Happily this situation resolved itself! It was fantastic to meet the authors, especially Desi Hristova who joined us on our walking talking tour of Marble Arch. It was fun to show them the truth behind the stats of an OpenStreetMap mapping party. They said they will be giving some presentations about their work, so I'm imagining a slide deck full of serious stats followed by sudden digression into pub photos!
So the people who wrote about the mapping parties, and about attendance of new people at mapping parties, then attended the mapping parties. Self-referential! particularly as they significantly boosted the number of new people who were at the mapping party. The question is... will we retain these new people? Also how many new people will come to our next event.
Well as a matter of fact, our next event is TONIGHT! Although in the new scheme of alternating event formats, tonight's one is not a "beginner friendly mapping party", but a "social pub meet-up". We do have the next mapping party scheduled in for Thursday 14th June and I'd like to try to promote this to new people again (any help appreciated). but I'm afraid I didn't pick a location yet. We will discuss this in the pub tonight! New folks are also welcome at the pub of course, and there are in fact a few of them expected! See you in the Blue Posts from 7pm. Details on the wiki
I went for a longer than anticipated hike 8+ miles then added the trails to OSM. The new Id editor is great! Drag and drop gpx files! Very good.
Thanks mapjunkie and cvo-osgis for inspiration.
Added the OTHS Panther Dome, Weber Field, the OTHS Parking Lots, and the OTHS Tennis Complex to O'Fallon Township High School, added Laverna Evans Elementary School, updated attribute data for Hinchliffe Elementary School and geometry and attribute data for Hesse Park in O'Fallon, Illinois.
It's been another stormy and rainy memorial weekend. Never seems to fail as soon as you get some time off or free time to do chores around the house that need done outside it has to rain all weekend. Never seems to fail, it sure seems like every year it rains on memorial weekend.
I've been looking at the other islands in the Commonwealth of Northern Marianas Islands, and it looks like all the TIGER data is in a sad state. I think I'll start with Rota and begin editing the roads by hand. There aren't a lot of them, only 377 TIGER roads, and Rota is a lovely island that deserves the attention.
I think the roads are less distorted in Rota than in Saipan because it's closer to Guam, which was used as a survey base for many of the older maps.
I don't have good GPS data for Rota, but I'll ask my friends up there to see what they can do for me. The satellite imagery is also pretty well registered, from what I've seen. If all else fails, it's a good excuse for a vacation to Rota for a few days.
Thank you, xeen, for the information on using relations for bus routes. I just wish that all this stuff was in one place.
It appears that I have to do each variant of a bus route as a separate relation. This seems very cumbersome: one of the routes here has six different opt-outs (same spine of route, but serves different roads/villages/estates at different times of the day) and all of them are possible. Each trip seems to be different; am I really expected to create 64 separate relations (albeit grouped together under route_master) ?
Am I supposed to create a separate relation for a route whose "opposite direction" is a simple reversal of the "forward direction" ? What if the "reverse" route differs only by the path it takes round a roundabout ?
I've noticed that while the data for Guam is generally pretty good, the data for Saipan is in a pretty sad state. In particular, the streets are distorted, and up to 60 meter off from their true location. You can see this by loading the streets on a Bing or other satellite image. This is starting to create problems for folks using GPS and other tools that use OpenStreetMap as a base source.
Most of this appears to be due to bad TIGER data during the 2008 import. Back in the bad old days, Saipan and the rest of the CNMI used a variety of old datums and projections, some of which weren't clearly documented. The TIGER data was on one of these, as was a lot of our old data from USGS, and the roads and related data are offset and distorted as a result. Even Google Earth uses bad old data.
My goal over the next six months is to replace all the distorted road data with TIGER 2012 data, or with equivalent data sourced directly from the government of the CNMI (i.e. Saipan). I'm frequently on Saipan and have worked with their data and analysts, so am confident that I can make this work.
Most of the TIGER data for Saipan is unreviewed and unedited, so doing a batch replace will have limited impact on existing users' work. A similar project was done for parts of Alaska by pnorman.
Things to do: 1. Update shoreline with NOAA data 2. Update shoreline with 2013 imagery to reflect ongoing erosion 3. Locate appropriate data 4. Figure out the scope of the problem (e.g. only roads, all TIGER linework, GNIS?) 5. Make sure folks in the area/community are on-board. 6. Prioritize fixes (probably start w/ roads, as that's most annoying to me) 7. Start implementing fixes by priority 8. On-the-ground GPS work to check fixes 9. Invite other folks to review
One of my side projects for OpenStreetMap mapping is the mapping of public transport routes in the New York region. This consists of New York City Subways (Map), Manhattan Bus Routes (Map), several Queens Bus Routes (Map) and Staten Island Bus Routes (Map). You can now view most local bus routes on the transport map and quickly locate nearby routes without navigation the maze of most local transit authorities websites.
The remaining items on the lists are several cross-town services, Bronx services and transportation on the New Jersey side. On a side note, an alternative rendering of the public transport map can be found at OpenPTMap, where subway lines are also rendered properly.
Good news for those missing SOTM in Birmingham or living close to Baltic Sea.
