Frustration about iD editor's inability to easily draw rectangular buildings

Posted by Polyglot on 15 December 2017 in English (English)

This tweet inspired me to write a new diary entry.

BHousel does not like the criticism he's been getting for several years now.

Drawing rectangular buildings using the iD editor is a lot harder than it ought to be.

My opinion is that if you create a tool that is going to be used by thousands of mappers, you owe it to your users to make sure that they can produce quality work with ease. Especially if the effort to do so would outweigh by an enormous ratio the frustration shoddy work creates for HOT's validators (and (re)mappers using that other mapping tool), who need to put more time into fixing the mess, than they would have actually mapping those buildings themselves in the first place. It's not like the science of creating a rectangle based on adding 3 points using 3 clicks still needs to be invented.

This is an ongoing problem for many years. So either it gets fixed one day, or frustrated messages will happen to escape, every once in a while. Or they will get muffled and HOT validators will continue to silently give up on trying to fix the deluge of poorly mapped buildings. Or you can simply unsubscribe from HOT's Twitter feed. Whatever works for you.

A more constructive solution would be to invite other programmers into the project. I can't imagine there wouldn't be candidates.

Here's hoping that something good can come out of this.


Being a mapper in a slow Internet connection country (SAS.Planet + MBTiles Plugin in JOSM)

Posted by Kampar on 15 December 2017 in English (English)

Well, I should be proud of living in a country where its internet connections were sucks. Updating JOSM plugins and imagery tiles are nightmare!

But, I eventually found a better way to tackle this awesomeness, with downloading all necessary imagery tiles with SAS.Planet, exporting those tiles into single MBTiles file, then, load those mbtiles file into JOSM with MBTiles plugin.

Camp Smith, Peekskill, New York

Posted by ke9tv on 14 December 2017 in English (English)

I've been trying to get public land boundaries in New York State tidied to where trail maps will show reasonable results for the parks and forests.

One problem that was recently called to my attention was Camp Smith in Peekskill, New York. Researching this area revealed rather a complex history, and I thought that I had better write this diary entry to explain what I did, since it doesn't quite agree with any of the 'authoritative' data sources.

Camp Smith, purchased by New York State between 1923 and 1940, is a National Guard post, and as such, is State land rather than Federal. The Hudson Highlands State Park that borders it is also, of course, State land, and in fact, portions along the north of Camp Smith had been carved out of it historically to create a corridor for the Appalachian Trail.

On that state land, a trail from the Bear Mountain Bridge to the summit of Anthony's Nose has existed for a very long time. I know that I visited Anthony's Nose as a Boy Scout in the late 1960's. Since at least 1993, there has been a trail open to the public that takes a strenuous course from there southeast along the cliffs, with many fine view overlooking the river. Everyone understood it at the time to be a way along which public access was granted, that traversed the grounds of Camp Smith.

In 2001, the political climate of the time forced Camp Smith to post its borders as being closed to the public. The recreational opportunities were restored in 2002 (at the same time as the historic site was created for the old Bear Mountain toll house) by changing the land management. The Hudson Highlands State Park was expanded to 50 feet northeast of the trail center line, and all of the land between there and the rail grade on the riverbank came under the management of New York State Office of Parks, Recreation and Historic Preservation. The flyer that is given out at the trailhead details this situation, and warns hikers that they may encounter the occasional patrol of Guardsmen, to whom they should give way.

Since this move was, in effect, a transfer of land from New York State to itself, there was very little formal record of it, and the official maps all still show the old boundaries. In many cases, owing to database incompatibilities among the state agencies, even the official maps are full of gaps and overlaps at the border between the two reservations.

It seemed important to me to indicate that the trail on the cliff top is open to the public, not subject to the restrictions of the military post. I therefore adjusted the boundaries of the military reservation as follows, and conflated them with the boundaries of the state park:

  1. A line fifty feet from the trail was created using the 'buffer' function of GDAL, and became the boundary wherever it penetrated into former Camp Smith lands.

  2. The (otherwise questionable) import of Camp Smith from a Federal database was retained. Where it was adjacent to roads, it aligned well to the road network and to aerial images. In the woods, the borders are indefinite in any case. The Westchester County portion of Hudson Highlands had originally been reconstructed from county tax data, which were recognized to have problems with alignment, partly due to mixed datums.

  3. Anywhere that Camp Smith and Hudson Highlands were coterminous, their joint border was replaced with a shared way.

This is pretty close, I think, to the situation that exists in the field. Indefinite borders are always a bit of a headache, but this change should at least clarify that the hiking trail is open to the public.

Bibliobús Municipal de Málaga

Posted by dcapillae on 13 December 2017 in Spanish (Español)

He terminado de mapear las bibliotecas municipales de Málaga, ya están todas en el mapa. Todavía se pueden mejorar ampliando su etiquetado y retocando algunos detalles, pero ya se pueden encontrar sin más que buscarlas por su nombre. También he mapeado las paradas del Bibliobús Municipal, nuestra biblioteca pública itinerante.

Si tenéis bibliobuses en vuestras ciudades, os animaría a mapearlos. Suelen dar servicio a nucleos poblacionales aislados alejados del centro de las ciudades y que no disponen de bibliotecas. Para muchas personas, especialmente jóvenes y personas mayores, supone un servicio público esencial.

Hace tiempo tuvimos una discusión en la lista de correo de OSM España sobre la forma más adecuada de mapear los bibliobuses. Finalmente he optado por crear una relación tipo «route» y no usar la etiqueta «highway=bus_stop». Los puntos de parada los he etiquetado simplemente con sus nombres, sus horarios y una breve descripción. La información común a todas las paradas la he etiquetado en la relación tipo «route» que define al bibliobús.

Lo más engorroso ha sido tener que poner los horarios en todas y cada una de las paradas. En algunos sitios, el bibliobús pasa semanalmente, en otros quincenalmente, con horarios distintos en verano que durante el resto del año. Por lo demás, mapear un bibliobús es muy sencillo.

Existe una etiqueta que se puede usar para evitar tener que poner los horarios uno por uno, «opening_hours:url=*», enlazando con una página web externa donde se puedan consultar en línea. Como solución provisional, no me parece mal. Sin embargo, siempre que podáis, os recomiendo que los agregéis manualmente para tenerlos en nuestra propia base de datos OSM.

Málaga cultural

Posted by dcapillae on 13 December 2017 in Spanish (Español)

He empezado a mapear la red de bibliotecas públicas de Málaga, algo que me propuse hace tiempo, aunque no le había prestado atención hasta ahora. De hecho, pensando más en general, me he propuesto mejorar el mapeado cultural de la ciudad.

Si estáis interesados en temas culturales de Málaga y queréis colaborar, echadle un vistazo a la página temática que he creado en el wiki. Intentaremos coordinarnos para mejorar el mapa en todo lo relativo a características culturales: bibliotecas, museos, centros culturales o de arte, patrimonio histórico y cultural, etc.

Si logramos poblar el mapa con todas sus características culturales, demostraremos que Málaga es una ciudad culturalmente rica, y evitaremos que se repita aquello que se decía antiguamente: «Málaga, ciudad de mil tabernas y una sola librería».

Mapping party at Wayanad

Posted by Hemantcompiler on 13 December 2017 in English (English)

This is the first time I went on a mapping party and that too to Wayanad. I didn't know much before about what a mapping party is, but I looked up on the internet and realized that we will be learning how to map areas on Openstreetmap and will meet the community and the people contributing to it. Actually if any type of event is happening in Wayanad, you can be assured that you will have a good time. Its such a beautiful place, you cannot miss the chance to at least see it once :)

I asked Praveen sir about how to reach there and we decided to go from KSRTC bus stand from Calicut. The journey from Calicut to sulthan bathery was just mesmerizing, I witnessed the beautiful sunset in the hills from the bus. I was just hoping that the bus get some malfunction and stop there so that I can look at it for a little longer. And you can even see pineapple farms there, they were just beautiful. There were even people selling pineapples on the road sides. I wonder how fresh the pineapples were, its like you can ask them to pluck a fresh pineapple for you!

Also being an open source software user and supporter, to discuss what all is happening in the world is just awesome, It was like feeding your soul. And since we are talking about feeding, the food there has just another level of awesomeness. At first I was reluctant to try the food as I wasn't sure what it is made up of. Then I tried puttu, and it had no taste, and then they told me that the taste of that depends on the curry. So you better have a good curry!! Puttu mixed with curry tastes delicious, it's just that I wasn't able to find the right curry :) A tomato curry would have been the one, I will try that next time. If you are a dosa fan but not much of a fan of potato, then let me tell, there is a thing called "ghee roast dosa", you should definitely try that and even better is appam. The only thing that I didn't try was idiyappam and I still think that I should have tried that. I missed the opportunity :)

The discussion on the dining table was about all the things going on in the technology world, I was happy that I wasn't the only one reading about those things. We talked about all the cryptocurrencies, payment gateway of telegram, then out of nowhere elon musk came in (Boring company, tesla and spacex), and then the MINIX OS. Then sombody probably Joice mentioned Abish Mathew, and NOBODY knew who he was and there ended one branch of the conversation :). Apparantely elon musk is more of a concern than Abish :)

Apart from that we mapped many parts of the sulthan bathery town. We got divided in a group of two each and started mapping on our own. The best thing about mapping is that you will know each and every path you mapped (Try creating a mind castle out of that !), next time when you go there. The first application that Sruthi mam suggested was Vespucci. It's a nice application and it reduces your work a lot, you can directly upload the data as you map. The first day I mapped with Vespucci only. Later in the evening I realised that Kannan and Ambadi were mapping with OSMTracker and the cool thing about that is you can actually see the trail that you went through on the map. I liked OSMTracker and the next day I used that only. We specifically went through some of the less travelled paths and as Kannan told me, we were able to create new paths on the map. Although that path won't be named after us but still good to know that we added it on the map and that information might help someone some day.

Just to travel the paths less travelled we went through the roads in the fields and there I realised that kerala fields are very diverse, you can literally grow anything here let it be banana, coconuts, pineapples, coffee, tea and lot of other things that even Kannan didn't know the names of and mind you that Kannan is from kerala :) The next day was to say goodbye to all, we went on our separate ways, and even on our way back we visted Pookode Lake. Although it is a great place but we found the parking the "Hard way" :) And probably somebody would have mapped it now (Ambadi?), so you won't have any problem finding it.

And now whenever I am bored I start OSMTracker and just go by some weird routes and map it and share it with my friends so that they can also try that route :) Waiting for the next meetup :)

Neuer Eintrag auf OSM (review requested)

Posted by oltoX on 12 December 2017 in German (Deutsch)

Also mir war nicht klar, dass in OSM ein neuer Eintrag doch etwas Zeit in Anspruch nimmt. Zur Qualitätssicherung habe ich bei meinem neuen Eintrag die Option "review requested" gesetzt und nun findet sich anscheinend kein Reviewer für den Änderungssatz: 54273048

Bin gespannt, wie lange sich das hinzieht....

Ein Blogeintrag gibt den Hinweis auf das neue Feature.

Ich werden mir wohl auch mal Zeit nehmen andere 'reviews' zu bearbeiten.

Juntas de Distrito del Ayuntamiento de Málaga

Posted by dcapillae on 11 December 2017 in Spanish (Español)

He añadido al mapa la ubicación de todas las Juntas Municipales de Distrito de Málaga. Ya se pueden buscar directamente desde sitio web principal de OpenStreetMap, sin más que teclear «Junta de Distrito», el nombre del distrito correspondiente y agregando «Málaga», para especificar el municipio.

En Málaga tenemos once Juntas de Distrito, una por cada distrito municipal. Las Juntas Municipales de Distrito tienen como función principal fomentar y velar por la participación ciudadana, aunque también funcionan como unidades administrativas. En ellas se encuentran la Oficinas Municipales de Atención a la Ciudadanía (OMAC), que son el punto de contacto más directo entre el ciudadano y la administración local. En estas oficinas, por ejemplo, es donde se solicitan los certificados de empadronamiento, entre otros muchos trámites que se puede hacer.

El mapeado de Juntas de Distrito completa mis otros trabajos de mapeo sobre distritos y barrios de Málaga. Me ha parecido importante que no faltasen en el mapa, ya que suelen ser puntos de referencia para cualquier trámite administrativo que se pueda necesitar, y conviene que se puedan encontrar en OSM. He añadido toda la información de la que dispongo (direcciones, horarios, teléfonos, etc.), para que cuando alguien busque donde está la Junta de Distrito de su barrio, tenga toda la información disponible.

Pirate Open Street Mapping Party Wayanad

Posted by Joicemj on 11 December 2017 in English (English)

It was fun mapping Wayanad. A district known for its environment, ethnic people, sensitive areas, Hills, Forests and of course Rain.

For the very first time, J4v4m4n, Pirate Praveen suggested the idea of pirate mapping parties. To be exact, 5 months before, he started a new thread on Loomio as a proposal to contributing to open street maps as [Pirates]( Later the discussion lead to mapping parties around Kerala. When Praveen completed Kannur, I asked him for one here in Wayanad. Exactly a week before 9th of this month, Praveen told me, we can host on 9th. I got excited as well as nervous. I don't know what to do, How to arrange accommodation, where to map, etc. I was really worried about bicycles. I thought cycles could speed up the mapping process. Another headache was whom will help us in mapping. Tada.. Ranjith Siji, Mujeeb, Kannan, Ambadi, Tanzeer, Sruthi, Hemanth came up to fulfill our plans.

Next to resolve was accommodation. Sreejith Koiloth helped us to rent DIET hostel.

Into the real fun

Sruthi, Praveen and Hemanth reached Bathery on 8th. Had dinner from Aravind Mess House. And then headed to DIET hostel. We made some plans for the next day. Discussed a lot of things too. On 9th December of 2017, by 8'O clock, Ranjith Siji, Mujeeb, Kannan and Ambadi reached. I picked Tanzeem and we met everybody at NRS bakery, Sulthan Bathery.

As planned earlier, unto noon, we mapped Sulthan Bathery. we grouped by 2. Me, Tanzeem and Praveen became a group. Ambadi and Mujeeb became next, Sruthi and Hemanth, Ranjith and Kannan and so on. By 12.30, We covered Almost bathery. After that we sat on a bench and discussed about the progress. Kannan came up with a digital SLR camera. He made couple of beautiful snaps. ( He haven't yet shared any of them. I will update whenever I recieve them)

Next was fooding time. We came back to NRS, Had food. I think me, Praveen and Tanzeem ordered regular rice. Kannnan is a different character. After watching Food Inc, He became kind of insane. He stopped having non-vegitarian. I wonder a documentary is having this much impact! He had a little salad. Sruthi too!! She joined Kannan's league. I love to have discussions. I am feeling like organizing and participating these such events opens a wide door for dialoges. We discussed about rural network connectivity, intel-minix prob, Food Inc, global warming, cattles and global warming etc. Ambadi was arguing for cattles as major cause for global warming. yea, It was lot of fun. On that table, we discussed about afternoon session. Again we grouped by two and started mapping. Praveen, Tanzeem, Sruthi, Mujeeb, Hemanth headed to Kalpetta. Somebody mapped Meenangadi, some Muttil and people left mapped Kalpetta. they reached back by 7 in the evening. I felt happy that, me and ranjith siji joined as a group and mapped a long area. We went by bike. Center For Social Computing offered a motor cycle and we headed to Pulpally. I personally got thrilled when we added a new road to the map. I told him different myths about wayanad, The origin of Sulthan Bathery's name, people etc. in shorts, we discussed our thoughts on food culture, wikidata, wiki commons, economy, economics, My AI Fear etc. We reached Nadavayal to have Kappa Biriyani. We headed to Varkey's Hotel. Kappa biriyani was not that good. but not bad. Anyway, Ranjith didn't like it much.

10th was the last day of mapping. I was home. I had some engagements. So I directed them to head towards Muthanga. But for the fate, time was over. They mapped something else. Then we planned to map Panamaram. I reached panamaram. By noon, They also reached there. Had some food from MAH hotel. Then ranjith took some photos of river and bridge etc. by 3'O clock, everybody except me and Tanzeem left for home. Then Tanzeem and me covered Panamaram. By 5.30 PM, Mapping party officially finished.

SMART/DDOT overhaul

Posted by NixillUmbreon on 11 December 2017 in English (English)


As I write this, a complete overhaul to SMART/DDOT relations is being uploaded to the server. I did this for two reasons.

Reason the first:

When I last "overhauled" SMART relations, I admittedly made a huge mess of things. There were two reasons I did this:

  1. I thought it'd look nice on the transit map with each route number getting rendered just once per road.
  2. I didn't want to have to add the bus stops to all the relations and risk forgetting some.

So what I did was made route segments and route segment segments.

I apologize for that, now realizing that it's wrong. Plus, the second point above is invalid, as I've since discovered; I can edit multiple relations simultaneously.

The first reason for this overhaul is to fix that.

Reason the second:

Data for both systems was horribly outdated. For example, there were still bus routes depicted on Woodward south of Campus Martius, which hasn't been the case since the QLine construction started. The DDOT relations still used the old public transit format! So the second reason for this overhaul is a data update.


There are a lot of bus routes I haven't ridden:

  • Almost all DDOT routes outside of Downtown
  • SMART routes 160, 280, 445, 475

For these routes, I've put my best effort to mapping them accurately, though in some places I simply could not tell where the route was intended to go (see: 38 at Harrison, Sears, or Outer Drive).


Official bus schedules and maps can be found at DDOT, SMART, and RTA. Additionally, for the RTA and SMART routes, some details not shown on the maps were mapped from personal experience.

For some DDOT routes where I couldn't tell what was what on the map, I followed roads that were part of the pre-existing relations.

I also used a bit of OpenStreetCam data to figure out which way buses went around loops.

Lastly, DDOT's GTFS file is public-domain, and helped me figure out a couple things as well. It can be downloaded here.

What's next

I'm going to take a short break, then in 2018 ride all the SMART routes and record out the bus windows and put the videos on YouTube. I'll license the videos for free use for open-source mapping projects - anything you see or hear on the video will be fair game to add to the map.

I personally will use the videos to map bus stops, and add them to back the relations.

2017 Board Election Statistics

Posted by Tordanik on 10 December 2017 in English (English)

The anonymized ballots from yesterday's OSMF board vote are available as a handy text file on OpaVote, so I decided to play around with them a bit. Here's a breakdown of the rankings for each candidate:

Heather Leson (1: 179, 2: 67, 3: 45, 4: 71, 0: 127), Joost Schouppe (1: 118, 2: 223, 3: 66, 4: 34, 0: 48), Paul Norman (1: 129, 2: 105, 3: 54, 4: 50, 0: 151), David Dean (1: 52, 2: 62, 3: 168, 4: 64, 0: 143)

I was also curious if people usually filled in the maximum of four slots, or left some of them blank. This is the result:

  • 0 candidates: 11
  • 1 candidates: 21
  • 2 candidates: 124
  • 3 candidates: 114
  • 4 candidates: 219

So most people did indeed list 3 or 4 candidates! With STV, the third place can matter even if there are only two seats available, so it makes sense to fill it in. Nevertheless, I also looked more closely at the top two spots to see if there are any interesting correlations. Based on all ballots with at least 2 candidates, here's the popularity of top two pairings (the order of candidate names carries no meaning):

  • Heather/Joost: 166
  • Paul/Joost: 136
  • Paul/David: 46
  • Heather/Paul: 43
  • Joost/David: 33
  • Heather/David: 33

If there are any other statistics you're curious about, feel free to ask – if I find the time, I'll be glad to run them. :)

Algo que ainda gosto de fazer no OSM

Posted by ivaldonm on 10 December 2017 in Brazilian Portuguese (Português do Brasil)

Finalizei a delimitação dos bairros de Rondonópolis - MT/BR. Demorou um pouco e deu trabalho, mas foi gratificante, principalmente por ser uma das atividades que ainda me motiva a contribuir para a plataforma.

Digo ainda me motiva pois o mapa já esta bem completo. Basicamente há poucos locais sem vias, e as tarefas atuais se limitam aos POIs, assim como as correções, que são coisas que não gosto muito de fazer.

E por quê a delimitação de bairros ainda me fascina e me motiva a contribuir? Nas cidades com plano diretor, onde num projeto urbanístico o bairro encabeça o projeto, isto e, antes de existir um logradouro, primeiro tem que existir um bairro. Assim, nome de ruas podem se repetir quantos vezes for necessário dentro de uma mesma cidade.

Nesse contexto os céticos podem dizeṛ "isso não existe, impossível". Se a cidade estiver devidamente delimitada eh perfeitamente possível. Dai a importância da delimitação dos bairros.
