A quick mash up I did of GeoRSS, Fire data, and Open Street Map's overpass API
Posted by CloCkWeRX on 13 May 2013 in English (English)Blogged about @ http://clockwerx.blogspot.com.au/2013/05/consuming-georss-and-querying.html
Relatively low effort to pull together - 10 hours perhaps? from start to finish, split over two sessions.
Demonstrates * SimpleXML/PHP to consume the overpass API and results * Simple Leaflet usage * Rendering of polygons from OSM data.
Toady I started using OSM Marker to take GPS Data.
I think there must be a very large number of GPS trace points at the intersection of the equator at the prime meridian (what's that place called anyway?).
I'm afraid I've been fool enough to add quite a few of these myself! Oops. Sorry.
I've modified one of the gpsbable scripts that I use to prepare NMEA files, chopping out anything around (0,0), so all should be fine from now on.
I really love this new editor
by mapping a relatively small community college campus. I have been using the iD editor exclusively. Wish me luck!
Unexpected items in the bark garden.

Very pleased with the new editor. This can be a tipping point of community mapping.
So I just learned that every single variant of a route is supposed to be a separate relation. I decided to start going through the schedules to find out all the specific variants...
And then route 200 hit.
Here are all the variations for route 200:
- 200 | Fairlane Town Center to Larned & St. Antoine
- 200 | Fairlane Town Center to Michigan & John Hix
- 200 | Fairlane Town Center to Newburgh & Enterprise
- 200 | Larned & St. Antoine to Michigan & John Hix
- 200 | Larned & St. Antoine to Michigan & John Hix (Express route)
- 200 | Larned & St. Antoine to Newburgh & Enterprise
- 200 | Michigan & John Hix to Fairlane Town Center
- 200 | Michigan & John Hix to Larned & St. Antoine
- 200 | Michigan & John Hix to Larned & St. Antoine (Express route)
- 200 | Michigan & John Hix to Larned & St. Antoine via Fairlane Town Center
- 200 | Michigan & John Hix to Michigan & Wyoming
- 200 | Michigan & Middlebelt to Larned & St. Antoine
- 200 | Michigan & Wyoming to Michigan & John Hix
- 200 | Michigan & Wyoming to Newburgh & Enterprise
- 200 | Newburgh & Enterprise to Fairlane Town Center
- 200 | Newburgh & Enterprise to Larned & St. Antoine
- 200 | Newburgh & Enterprise to Larned & St. Antoine via Fairlane Town Center
And that's just the fourth route!
it really is easy to use and I like the design very much. However it is really slow on my computer. Tried it under chrome and firefox but editing an area with more than e.g. 15 buildings it gets really unusable. The CPU-usage goes up to 100%. I'm wondering why this problem (and I have a quite fast computer) (nearly) isn't adressed at all those news about the iD editor...
I hope that it gets faster in the future and that this problem is not caused and / or limited by HTML5 and JavaScript :(
Woo!
Well, here I am, obsessively mapping the world around me. Major project underway: mapping the Monterey Institute of International Studies, where I am a student!
I'm afraid of google. It's everywhere!
I couldn't make an account for the wiki because it uses google's recaptcha. Looks like the new ID editor uses google's analytics...
Not sure if there is an easy alternative for the captcha problem but one certainly could use some other user tracking software, like Piwik. Or any one of these https://en.wikipedia.org/wiki/Category:Free_web_analytics_software
Added geometry and attribute data for Sparta Community Airport-Hunter Field, near Sparta, Illinois. I flew out of here last year. Added Belleville RC Flyers Field, a remote controlled aircraft airfield run by the Belleville RC Flyers. Located between Scott Air Force Base and Belleville, Illinois. I visited there yesterday. Added geometry and attributes for the Julius J. Knobeloch Woods Nature Preserve near Freeburg, Illinois.
Updated geometry and attributes for Rock Springs Estates in O'Fallon, Illinois.
Updated geometry and attribute data for Litchfield Municipal Airport, Litchfield, Illinois.
I have just finished a QGis Portable How-to for Lisboa 1.8.
Posted by DevineMe on 7 May 2013 in English (English)I been using QGis with map data in portable mode for a while. I have finally gotten around to writing a how-to on my SourceForge site. Process is pretty strait forward with all scripts available in a download. Article is located here
Hi guys,
I've joined OSM several months ago and made hundreds of edits but I've made no diary here... Hmm.. let's say... in this very first note, i'll tell somehthing about me and my mapping hobby.
I was born in a seaside town called Vũng Tàu, which is about 125km southeast of Ho Chi Minh City (a.k.a Sài Gòn). Life was peaceful until 2008 when I came to Sai Gon for college and work. . Hmm Saigon, frankly speaking, is a messy city, and even though it's a fast developing urban area in Southeast Asia, infrastructure are not really fit with the trend.. however, thanks to 'smart' anti-automobile policy of the govt, we don't really have serious traffic jams similar to nearby metropolitans like Bangkok or Jakarta. Most of us, well, around 80% or more, ride motorbikes to work and school everyday. And despite its inconveniences (distance, speed, weather conditions...), it brings more leisure on the road.
I like maps and geography since I learned how to read and write. Hmm,... when I was 7 or 8, I visited my neighbour, and suddenly got interested in a globe in his living room. I then asked him to see the globe and couldn't really kept my eyes out of it for 3 hours. Coming back home I told my Dad to buy a world map, and since then I started to look at it every day. Hmm, it was really unusual for a kid at primary school age who didn't like to go out for play sports or music~~, but he chose maps instead.
I developed mapping hobby when Google launched 'Mapmaker' project. At first I was really keen on contirbuting for the project, but then I discovered that Google Mapmaker was not smart enough.
Community approval policy : Every edit needs approval from others in a voting system. This is a time consuming process, especially when there are not enough votes for your contributions.
Lack of respect of differences : Some contributions which are out of concern of others, including supervisors can be turned down. Well, I spent two hours adding several paths in parks and a museum (Reunification Palace) in HCMC, and submitted them. The only answer I received was that 'pathways are good but they are UNNECESSARY, because our Maps features should focus on roads and the use of GPS when traveling'. I told them that even though it seemed cars don't use it, but 'pathway' can help describe the ways for walkers or visitors.
Moreover, 'pathway' is available in the toolbox, and we should make use of it . I then pointed examples of parks and university campuses elsewhere in the world, such as Georgetown University in Washington, D.C and riverside parks in Singapore. What I received was that 'Well, they are different cities, and we're in Vietnam, and we're different'.
Well, then I said goodbye to them because I felt that those conservative mapmakers do not respect me and my and turned to OSM a few months later.
All mappers, particularly newbies, should take a look at http://keepright.ipax.at/ for sources of maplint.
I've noticed two maplint trends in Oregon: a) A bunch of "This node is not a member of any way and does not have any tags." Presumably, this lint was left behind after The Great License Change redactions. It seems like it would be a good thing to have a bot go through OSM and remove points that fit this description. Why is that not a good idea? b) I've seen a lot of people creating areas (playgrounds, buildings) then giving one of the nodes the tags. No no no. I believe if a business occupies an entire building, it's OK to tag the building, not just a node. In the case of playgrounds, it makes no sense at all to create an area then tag a node.
Anyone seen trends in their area?
Ordnance Survey have just released their May 2013 version of OS Locator, the comprehensive gazetteer for GB. According to my calculations there are 5247 new entries and 3694 removed entries since the last release in November.
I've updated my comparison tool Musical Chairs with the new data. New entries tend to show up prominently in the "recent relevant updates" view mode for a few days after an update, so this is a good way of taking a look at what's changed in your area.
I'd suggest GB mappers take a look at their area, even if not for the purpose of mapping - new releases of Locator often reveal some interesting things about new building projects and developments.

Do OSMTrack on iPhone refers only GPS data, or also refers iOS map?
Posted by InsideRoomB on 4 May 2013 in English (English)The images on the following URLs show GPS tracks obtained using OSMTrack on iPhone4S. I get these tracks on the train (Yamanote-line) in Tokyo.

It is strange that some part of the tracks seems to follow the road, instead of railways. I suspect that GPS data on iOS might refer road data (but not railways) of Apple Map and tries to snap on the nearest road when it is moving fast enough.
How do you think? Please try with your iPhone, if you have.
If my speculation is true, OSMTack on iPhone is no longer suit for OSM mapping.
