New version 0.3.0. I added tags on the page "GPS Traces" and improved the user's diaries.
Public GPS Traces:
Mobile money agents are a fact of life here in Kenya. Over half of all adults use a mobile money transfer service. Locating an agent is often a difficult task, especially when you are in unfamiliar places. It would be nice if it were possible to add a mobile money agency specific POI.
Ordnance Survey have just released their November 2013 version of OS Locator, the comprehensive gazetteer for GB. According to my calculations there are 10,151 new entries and 7,730 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.
Something I just noticed on an application using "Mapbox streets" map tiles. When you click on the "Terms & feedback" link, you fall down here: https://www.mapbox.com/about/maps/
And what I read is that "OpenStreetMap contributors create and improve our map data". I find the "our data" "clumsy" for the best case or "dishonest" for the worst. When I contribute to OSM, I'm not improving the Mapbox map data, the "your" map data, displease you, Mapbox friends. I'm working for the OSM map data and you take advantage of it.
Roughing up the municipality!
First - wow! It's quite un-intuitive to add a traffic camera to OSM... http://wiki.openstreetmap.org/wiki/Relation:enforcement
Second - wow^2! No one seems to render the traffic enforcements. They're not shown on the default OSM rendering, and OSMand+ for Android phones (a navigation app that should show them) also does not include them.
This site scrapes the database every couple weeks and renders the enforcements. Enjoy! http://frink.bplaced.de/blitzer/
Delaware County routes and town borders done. It was surprisingly easy, and a number of sins along the NY/PA border were dealt with. I see more issues with the NY/PA border going west, and will look at that after i take care of Westchester County. Westchester will be interesting. the density of places with borders in Rockland County made adding the town borders more complex, and on the south end i need to make sure what i do is compatible with any border work done for NYC by Serge (User:emacsen). addtionally Westchester County routes are unsigned, so i'll be putting in route relations but will be using unsigned_ref instead of ref.
Took a hike with the family in Corbett's Glen. I captured the rest of Perimeter Trail with my GPS. I uploaded the traces and added to the map.
I used to use a complicated process to get the points off my GPS using the vendor's software. Now I just put the SD card in a reader and get the data directly.
The local area's pretty much mapped near me -- so I was interested when I saw the new project for mozilla https://location.services.mozilla.com/map_world
Just on a couple of walks I've spotted new features that I need to add to OSM -- which shows why it's good to remap.
Now if only there was one application that could do both...
-translated from my previous german diary entry-
Writing about mapping of a town here in the OpenStreetMap diary is really nothing special at all. Nevertheless, I´d like to explain some pioneer work in the outback of the Brazilian state of Bahia to all those which already may be a little bit accostumated to excellent maps, and show how the OpenStreetMap idea is divulged in a very simple way.
Primarily, "Novo Mapa de Itapetinga-BA" (transl. The new map of Itapetinga-BA) is a microblog established and maintained by me that offers to its portuguese speaking visitors - that still don´t know OSM - a direct map access to the urban area of Itapetinga in OSM (more than 99% of the mapping is made by me). Moreover, this site presents also some important and locally interesting applications which all are based on the OpenStreetMap idea, as suggested by the OSM symbol that focusses on the municipal coat of arms:
- Download of offline usable maps: high definition map sections of downtown Itapetinga, rendered wall and book maps as PDF files, as well as regional electronic sections from the OSM map for navigation in Garmin and Android mobile devices (App OsmAnd)
- Introduction of the Wheelmap acessibility project for the Itapetinga section
- Step by step guide for the installation of the OsmAnd app on an android smartphone, including the portuguese commands of the speech guided navigation in Itapetinga and region, as well as provision of a regional "ready to use" map section
- OSM based web routing machines and measuring tools, predefined for the region
- Public transportation grid in Itapetinga using the OSM bus relations and additional information about fares and timetables, the first and up to now (!!!) only web visualization of these local information
- Pepinogram (transl: cucumbergram on the basis of the regional circumscription of "problem" by means of cucumber (port. pepino)): a site established by me on the Ushahidi platform, where locals can denunciate problems, as like as waste depositions, noise pollution or wasting of public money etc.
- News: news which concern the blog itself, like the new symbol, news concerning regional map and satellite image availability or any other space related news which may be better explained, illustrated or understood by using the OSM map
- a short introduction about the site, about the OSM project, mapping and authors.
Hosting is done on Blogger.com (so, many thanks to Google!). The only charge which applies is the annual registration fee of the domain of about U$ 14.
As I already mentioned at the beginning, the idea of a regional compilation of OSM services seems to be banal and trivial, but it is not at all, at least in the Brazilian context. OpenStreetMap is (still) largely ignored in Brazil and should be much more popularized, particularly as there are other still more traditional, purely Brazilian crowdmapping projects (like "Tracksource", destinated exclusively to mobile offline users). I googled a lot in order to know if there is any other site in portuguese comparable with my blog, which present the OSM cutout and OSM based spin offs for a town or a region. Result: negative report.
The compilation of the project in form of a site makes it possible for me to know how many daily accesses there are more or less on the regional map section. At least all those accesses done by users that do not access Itapetinga directly on the OSM map, but that web-searched for (updated) Itapetinga maps or similar, and then found my site. Logically, as a convenient collateral effect, the OSM project is more divulged by this.
When we moved on May 2010 to Itapetinga (about 70.000 inhabitants), there were in the internet nothing but totally outdated and unreferenced maps of Itapetinga with unusual street names, whose errors are persisting mainly up to now. All the satnavs merchandized in Brazil used that bad map base and that way were eliminated as navigation alternative too. On OSM, for Itapetinga there was a simple "white spot". Not even satellite images with a better resolution as 2 m were available anywhere in the web. With many good luck I could find a black and white town map printed in 2007, which was not much better than the available web maps in terms of street name accuracy, not to mention the lacking street directory.
So, "if there is nothing, build your own" was the need of the hour. I didn´t know anything about the OSM project that moment and initially I began to draw a map with the help of CorelDraw and a GoogleEarth panchromatic hi res satellite image that appeared meanwhile. Buth this didn´t pay a lot, because I was already searching for an alternative for building a routable electronic offline map for my Garmin Colorado 300 device, and the Google aerial image brought about copyright issues. Searching for solutions I found OSM and began in January of 2011 to map the whole town by GPS, as until beginning of 2013 there were no hi-res satellite images on Bing. April 2011 www.mapaitapetinga.com.br went online. In 2,5 years there were almost 20.000 page views, and in the last months, the daily access numbers leveled out at about 33 (1000 monthly) views. The mapping of Itapetinga in OSM represents today an island of at least regionally unknown detail richness in maps (even if still a lot is missing), which I will enhance in the oncoming years by extension projects of the regional university UESB.
Maybe there are already people to whom the OSM lolcat of awezumnez is unknown.
Why is the bipolar 400 kV HVDC CU west of John Lake not installed on lattice towers, but on poles? Is it an experimental section or a temporary solution as the towers were destroyed by a tornado?
It is now time to mark a milestone in my month-long programming marathon and announce the first release of the MapBBCode library: a way to integrate maps into almost everything, but primarily written for forums and blogs. There is a long introduction on the official site, but the problem it solves is very common and somewhat annoying, especially with biking and construction sites: they have no maps.
Mapping plugins for forums tend to focus on geolocating users, which is a dull and useless task. What if I want to draw a route and allow fellow bikers to download it as GPX before setting off? The world of embedded maps is dominated by monstrosities, like the one I've spotted in Shaun's blog (40€ for a map!). We have Leaflet, we have the best map in the world, and forum/blogging engines have API — let's get coding.
As an example of library's versatility, MapBBCode Share website was born. The idea was simple: put strings in a database — and you've got a map sharing service, simple and accessible, like pastebin or imgur. And you can copy raw code to a forum or a blog. This vision started to shatter when GIS-Lab community used the site for planning a mapping party by openly publishing an edit link. And then I added import and export to a dozen of formats, personal libraries (so you won't have to store bookmarks locally) and API. It turned out that sharing maps is only a fraction of the site's potential.
Now you can plan a trip together with friends, place markers, embed the developing map in a forum post, and a day before the trip you can download the route and waypoints in GPX format right from a forum page. You can import CSV and immediately download it as HTML with no external dependencies (besides Leaflet). No iframes — unlike every other service, MapBBCode Share produces full-featured HTML that works offline and can be included in a website by copying code. You can upload OSRM-generated routes, quickly edit poly files, inevitably export GeoJSON, — the site "competes" not only with geojson.io and uMap, but even with JOSM. Privacy is bulletproof: you sign in with OpenID (google/yahoo accounts will do), your ID is immediately hashed before storing, so even the administrator doesn't know who is using the website. The hash doesn't leave the server, so no one can link maps to users.
Today I am releasing the whole package: more than 200K of code, 60K of documentation, 7 new Leaflet plugins, everything published under the most permissive license of all, WTFPL. The development goes on, but now all changes are logged, and the author is responsible for keeping backwards compatibility. Please use MapBBCode Share and write plugins for embedding the code into forum and blog engines. Let's make the [map] tag a standard, and make sharing maps no harder than sharing images or code.
The county routes now look good, except for one or two notes that need to be resolved. On to Delaware County Town borders! Here is a sample of Rockland County Routes with shields

London, the birthplace of OpenStreetMap, is already the largest city in the world to have lots of street light data. When I accepted the contributor terms a year ago today, it didn't have much.
This is the state of street lights, one year on – probably worthy of a mention on the weekly summary, but how do I get older snapshots of the OSM maps so I can compare it?
Happy Diwali everyone.
It says on the OSM wiki that Navilock NL-402U (which contains LEA-5H module) can be used with RTKlib with the right ROM installed. It was a surprise when I saw it, as I was planning on buying another receiver that can work with RTKlib. I've tried with u-blox's latest firmware, but it seems required settings don't show up as enabled in u-center. So...the "EXT" on the wiki is probably an unofficial firmware...
So far, no luck.
Had blackout for some time, streets and motorways are blocked everywhere around by trees or HGV turned over by gusts of wind, all trains and all ferries are stopped, a few people where injured, fortunately none died in our area (Edit: Sadly one man died in a town nearby - he was struck by a tree). Three trees in our backyard are overturned, the roof of our house and the rain pipes are damaged by flying parts but I saved the beehives just in time. The next days I'll be busy with chain saw, axe and other tools.
That's what I call a stormy monday!

hmmm ST_StraightSkeleton() ... what to do with it? :)
I should mention that the large building complex 'Hôtel des Invalides' is only one multipolygon tagged with roof:shape=hipped and CGAL takes 15 seconds to compute the skeleton for it.

this is a follow up to my last blog post http://www.openstreetmap.org/user/werner2101/diary/20213 about OSB phase out.
Things happend in the last two weeks:
- I've created a wiki page for it: https://wiki.openstreetmap.org/wiki/OpenStreetBugs/Phase_Out
- The tool to review bugs works fine now. (see next link)
- Improved statistic tool, creating this page: http://www.h-renrew.de/h/osm/osmchecks/09_osb_phaseout/
- osbbugs app no longer creates osb bug entries (thanks to the author)
- started to review bugs in areas with low bug density e.g. Africa, Australia, Alaska, ....
The bug count has been reduced by 3000 bugs in the last two weeks, other mappers have started to review bug entries in different places (Philipines, Ireland, England, Germany ...). Thank you.
But ... who is still adding so many bugs to the database?
Oh, someone creates bugs with bulk uploads.
Looking into the database, the new bugs look like this.

Wow, 11 new bugs in 5 seconds. Looks like someone is using OSB to collect mapping notes ....
Where are all the newly created bugs? Currently the open bug distribution created after 2013-10-01 looks like this:
- [RU] 1811
- [DE] 341
- [BY] 23
- [NL] 17
- [PL] 16
- [FR] 13
After disabling the OSB homepage 2013-10-15 looks like this:
- [RU] 716
- [BY] 22
- [DE] 5
- [IT] 3
Looks like the only major creator of new bugs lives in Russia / Moscow.
Please fix as many bugs as possible in your city, your county, country, ...
