OSM is a mapping project, but sometimes people write software to do stuff with OSM. Irish Townlands is one example of this. And that code (like much in OSM) is open source (see it here), and I use Github, since it's so popular for open source.
So I set up a Github organization for us! Here: OpenStreetMap Ireland If you're a Github user, feel free to join (on-line, or contact me and I can add you). I've already transferred the townlands.ie source code there. Feel free to transfer any other projects on github there.

I copied this into my userdairy to make it easier for people with questions about my use of traffic signs on island on areaised highways to find my reasoning. It was writen in responce to someone stuggling and deleting and modifing them stating as part of the conversation:-
I've corrected two of them, the last one is here: http://www.openstreetmap.org/changeset/36931147 Please read again http://wiki.openstreetmap.org/wiki/Key:traffic_sign regarding the use of highway=traffic_sign on a way / node and see this changeset
I think they had some fixed rules based on pre areaised uses that needed to be adapted to make sence of areaised highways https://wiki.openstreetmap.org/wiki/Proposed_features/area:highway https://wiki.openstreetmap.org/wiki/Proposed_features/area_highway/mapping_guidelines <--This is a new page I just found and am yet to study (ie not read before below was written...) https://wiki.openstreetmap.org/wiki/Proposed_features/Street_area <---This to also has new parts I'm yet to study too (for the same reason)
Comment from Govanus less than a minute ago
this sign was a very large direction sign. Somehow this needs to be a relation and not a phiscial way according to:- http://wiki.openstreetmap.org/wiki/Relation:destination_sign which is confusing to do to a real object rather than a virtual sat-nav indicator. there seems a lot of confusion possible till you realise that there are two functions of defining and indicating traffic signs in OSM Function 1: Alert the navigation system that a traffic rule is in action in a place or part of the road. Function 2: To indicate the location of street furniture used to make a physical sign displaying infomation to road users.
In simply mapped areas using a single way for everything then tags fit to way sections for function 1, and a point, with point specific tagging, carries function 2. Its been debated wether the point goes on and into the way (as all is 1-dimensional) or by the side like a more 2-dimensional form. The obvious over sign has hight seperating layering style tags to avoid confusion.
Now in more complex and more detailed mapping used for small area rendering like doorway approches etc meny line features gain full areas and it is logical to make point features of flat objects into lines carring the same tagging to give the same meaning especialy when signs become 10 meters tall and twice the width of the sidewalk like on the southen bypass. there are also box bolard signs used along this road when the flat ones where crashed into that was a cheap replacement. they may apper as tiny squares after being areaised the four faces can carry different signs when needed too (though I don't think the replacement one here dose and carries a non-sign on one side a black rimed white circle).
The function1 role for the traffic_sign UK:610 is given by forceing a split of the routing line at the correct spot to obay it, in an areaised highway. Remeber that the road now has lots of width as well as length and the routing line needs to follow the middle of the carrage way and not run over the sidewalk lamps and poles just drwan in the middle of the road, and this is the natural way to guide cars and busses past the features too (when some one measures the lane width changes and gives it in lane features it will make more sence too that lorries can take a staighter course but the routing line needs to fllow the middle for the logic of so meny other tags that get dumped on it. so that's why I drew them as I did. reading the wiki still dosn't seem to put this into question (especialy if you take the licence to convert points to ways when converting ways to areas when this make most sence when scaled to the phisical feature (ie the same size as real life)
The problem with this direction sign (in http://www.openstreetmap.org/changeset/36931147) is that direction signs don't commonly carry a common referance standard-drawing number in the pointed too offical traffic_sign manual because the signs a composed on a custom to site basis following some layout rules on stuff like spaceings and line widths and angles etc. So the function 2 tagging so far seems absent as only the function 1 seems covered so this sign needs to be here to be added to a form of more virtual sign defined here:- http://wiki.openstreetmap.org/wiki/Relation:destination_sign possibly as a new role type of physical sign board or something...
The sign contains sub signs too as well a very long winded textual execption list that will probably need a lot of special use of clausual tags (more common to parking) on top of this there is question make about the intergation this with lane tagging and/or diffend marking as although these are ghost lanes only the tagging for laneing carries a lot of this infomation on lane use and possible extions of the inclusion of detination tagging to complement this signs intentions, this is fitting more of the function 1 role. Finally the question of how to intergrate possible lane features that may be drawn in future into any relation for http://wiki.openstreetmap.org/wiki/Relation:destination_sign Is another question that will probably be answered as a yes included.
As I had run out of time for this doing the other 100 features needing offset correction I drew a simple sign board so it could at least be used for function 2 pedestrian navigation uses on the sidewalk (like "oh yes I'm here; because overthere's that huge sign shown on my map"). Also others might feel like finishing the puzzel for me as it wasn't finished.
Stefan is 28 years old and just finished his studies in resource and sustainability management (Joint Degree for Sustainable Development). Right now, he is looking for a job. He uses OpenStreetMap not only on a daily base for personal use, but also for his university research in order to visualise the distribution of cultural resources in cities. In future, Stefan would like to learn how to build his own map layers to show otherwise invisible buildings and infrastructures.
How did you discover OpenStreetMap?
The first time I heard about OpenStreetmap was at university. It was also mentioned in an edition of Arte, titled "Le dessous des cartes". But I only really started mapping after participating in a conference on the use of maps for the visualisation of sustainable economy and community initiatives. This initiative, called Transformap, hopes to produce thematic maps based on OpenStreetMap. After this conference, I took part in a monthly meeting of the OpenStreetMappers user group in Graz, Austria - where I was studying at that time. It is a very active group. Unsurprisingly, Graz is very well mapped. That motivated me to participate, so I started to map my own area, Hesbaye.
Do you use OpenStreetMap?
I spend a lot of time looking at maps. There is no other media that helps to understand, discover, or rediscover an area as well as maps. Maps also have the enormous potential to participate in the development of an area. I also have a smartphone with an OpenStreetMap navigation application, called OsmAnd. I use that app for navigation as well as an "ordinary" map of the place that I am visiting.
What kind of mapper are you?
Until now, I mostly did remote mapping in the area where I live: Hesbaye in the Liège province. But slowly, I started to follow some roads and visiting nearby areas to compare the map with the reality. I really like to discover new places thanks to OpenStreetMap. I do not have a real speciality, but by mapping my village, I learned a lot, especially concerning historical buildings. Since I want to show this patrimonium to others, I focus more on this topic at the moment.
What is your biggest achievement as a mapper?
Mapping the village I come from, though that is more like a never-ending marathon than an achievement. When I started, the Hesbaye region was barely mapped. However, nowadays, I notice that there are more and more mappers active in this area. Although I only contributed part of the data, I am very pleased that the map is getting more and more details.
How can we motivate more people to contribute to OpenStreetMap?
By organising Map-Jams and or workshops, e.g. in the Re_lab in Liège. By giving introductions to new mappers and teach them how they can use the different tools (JOSM, GPS, data imports) By organising regular meetings (once or twice a month) for mappers. By making a brochure with information for public services, companies, NGO's, computer scientist, etc. to promote the use of OpenStreetMap.
What is the strength of OpenStreetMap?
OpenStreetMap proved itself a couple of times to help people in need, e.g. after the earthquake in Haïti, or more recently during the ebola outbreak in West-Africa. The humanitarian intervention was more effective because the area was mapped by volunteers. The major asset of OpenStreetMap is without doubt its "open source" character. It is de-facto a common asset that belongs to humanity: everybody can participate -- of course you need an internet connection and a computer. Nevertheless it remains accessible for a large group. Those values are important and provide an alternative paradigm for the mantra of growth and commercial gain. I also believe that OpenStreetMap is a nice example of bottom-up internet organisation.
What is the biggest challenge for OpenStreetMap?
Exactly this internet governance. Unfortunately there are more and more examples of increased top-down control on the internet (for security reasons, economic issues, etc.). As often, there are good arguments for both sides, but I am convinced that open source software proves that the internet is a collaborative project that is for the benefit of all.
Anything else that you want to mention?
OpenStreetMap is really not difficult. It is a community with a lot of passionate people who use patience and enthusiasm to help anyone who wants to get their head around open source software. You can start by exploring the different OpenStreetMap maps and the rest will happen automatically!
O OpenStreetMap é mais que um mapa. É um verdadeiro banco de dados livre do mundo, onde você também pode colaborar. Esse mapa pode tanto representar o mundo de forma plana quanto tridimensional com Simple 3D buildings.

Myanmar is witnessing an unprecedented growth in international tourist arrivals following major democratic reforms since 2011. On OSM, around 70,000 kms of roads have been mapped so far, or roughly 42% of the total reported roadways.
Most of the major highways (motorways, trunk, primary, secondary and tertiary roads) are well mapped in the major cities of Yangon, Mandalay and Naypyidaw, but there are a lot of missing residential and unclassified roads visible in the imagery. Over a period of three weeks, the Mapbox data team was able to add a total of 7,690 missing streets, out of which 2559 and 5131 streets were added in Mandalay and Yangon respectively.
Missing streets in Mingaladon locality in Northern Yangon
Issues we faced
- Lack of an active Myanmar mailing list or forum made it difficult to reach out to the local mapping community for collaboration.
- Identifying the streets in densely populated places is difficult because of the buildings and thick tree canopy. Lack of GPS traces in these areas also hampered the process to add missing roads.
- There is a lack of road network classification guidelines for Myanmar in the OSM wiki and the general highway classification guide was used for this purpose.
- Most roads that were previously added seem to be from lower resolution imagery and required cleanup.
How you can contribute
- Prepare an OpenStreetMap wiki for the road tagging classification in Myanmar similar to Indian roads tagging classification.
- Community members can engage in contributing to other cities of Myanmar by adding missing roads.
- It would be good if local mappers can add more GPS traces so that we can add the roads covered under canopy and buildings.
- Community members can also review our edits and give feedback.

Embora esteja baseado em Campo Grande-MS/Brasil, estou trabalhando na criação, classificação e ajustes nas rodovias de Pernambuco, meu estado natal.
Pude perceber que existem muitas cidades médias (entre 15.000 e 50.000 habitantes) que ainda não estão no mapa. Além disso, muitas cidades maiores - acima de 50.000 habitantes - estão com o mapa incompleto, vias sem nomes, etc,
Então quem tiver meio ocioso e quer mapear algo, vá para Pernambuco e melhore o mapa de lá, pois existe muito trabalho a ser feito.
A minha ideia inicial é focar nas rodovias (criação, classificação e ajustes), pois existem muitas incorreções nas referências e classificação também, além de muitas que não estão no mapa. Depois vou trabalhar nas cidades.
I've trying to create "Proximity Alert" for my Garmin devices for more than 6 months and I couldn't yet. I will detail the steps that I'm following so maybe you can give me a hint on where is my mistake:
- Download data from geofabrick:
wget -c http://download.geofabrik.de/south-america/ecuador-latest.osm.bz2
- Uncompress file
- Filter data to get only "traffic_calming=bump" (that's what I'm interested in):
osmfilter ecuador-latest.osm --keep= --keep-nodes="traffic_calming=bump" > ecuador-traffic_calming.osm
- Create "Proximity Alert" with GPSBabel:
gpsbabel -i osm -f ecuador-traffic_calming.osm -o garmin_gpi,alerts=1,proximity=50m,speed=15kmh -F ecuador-traffic_calming.gpi
- Copy this file into my Garmin device. It recognices my file but when I pass trough the POIs it doesn't generate the Sonor Alarm.
Do you know what I'm doing wrong?
Tomorrow I'll focus on crossings. And then maybe trees after that.
We recently built this new tool which shows all amenities in a given area or between two points by dynamically spooling amenities using the overpass API. During the initial stage of the project, my initial though was just to have a POI map for Bengaluru but, we landed up building a map which shows POI's around the world.
Check this out - POI finder using OpenStreetMap data, it's a great outcome!
- Find POIs within a radius of 1km for any point on the map.
- Highlights all POIs within a radius of 1km for a route between any two points on the map.
- Filter POIs based on type.
- Using the Geocoding API, you can go to any place in the world and place a marker and it generates a buffer between the points.
We continue to think on ways to develop and improve this map. Thank you for reading!
... Kotzt mich an.
Für einen Englisch-Muttersprachler mag sich das vielleicht aus dem Zusammenhang erschliessen, mir nicht, und etlichen anderen offenbar auch nicht. Ich finde die Benamsung denkbar ungünstig. Dict.cc meint bspw. auch "housing terrace" oder "terrace houses". Klingt mir sinniger. Oder meinetwegen terrace_row.
Ich hab mich grad auf buildings spezialisiert (bzw. überlappende korrigieren) und da stoss ich ständig auf "Terrassen". Richtig, so ne Aussenterrasse am Einfamilienhäusschen mit Wintergarten meist.
Nunja, jetzt hab ich mal ne manuelle Auswertung (für Thüringen) gemacht, um mir ein Bild zu machen.
Sondern viel schlimmer.
Wenn man sich das Tag etwas schönredet und nicht alles auf die Goldwaage legt, findet man 75 Gebäude, die halbwegs ins Schema passen, bleiben nach Adam Riese um die 600 Gebäude übrig, die falsch getaggt sind. Bei den 600 sind recht viele zusammenhängende (terrace) Einzelgebäude einzeln als terrace gemappt:
Der Wille ist erkennbar ... leider falsch.
