Neuer Eintrag auf OSM (review requested)

mar 12 déc 2017 - 11:39

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

lun 11 déc 2017 - 18:18

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

lun 11 déc 2017 - 15:12

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](pirates.org.in). 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.

SMART/DDOT overhaul

lun 11 déc 2017 - 3:53
Background

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.

Caveats

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).

Sources

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

dim 10 déc 2017 - 21:11

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:

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

dim 10 déc 2017 - 19:14

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.

Thank you, now on with the next steps

dim 10 déc 2017 - 17:35

Thank you to all the OSMF members, fellow candidates, board, and outgoing board members. It has been a privilege to consider your priorities for OSMF via questions, notes, and conversations.

We are the community, the map, and the project. The lovely people who make OSM part of their daily flows count on all of us at OSMF to meet the full mandate and the full potential. This means considering, then building on how we might balance the growing, changing needs of the open, global, diverse community.

Over the past few weeks, the questions on the wiki and the conversations on this mailing list have pointed to some potential actions. Converting those requests and ideas into productive working documents for consultation is the next step. There are many people on this list and in the wider community that will contribute if there are healthy spaces and a clear ask. It is up to us in the membership, in the working groups, and on the board to make this possible.

Thank you again,

Heather

The history of HOT US Inc governance - not to be replicated in OSMF

dim 10 déc 2017 - 1:45

(EN automatic translation below)

Durant la campagne pour les élections 2017 au board de l'OSM, je suis intervenu par trois fois sur la liste de discussion OSMF :

  • ce premier courriel en anglais dans lequel je montre la faible implication de Heather Leson dans OSM depuis 2011.

  • ce deuxième courriel intitulé " Language, tone and their explanations - why I resigned from HOT US Inc", rédigé en français et traduit en anglais, pour expliquer le ton employé dans le premier via notamment ma lettre de résignation de HOT US Inc en 2016, que j'ai publié dans mon précédent billet de blog

  • ce troisième courriel intitulé "The history of HOT US Inc governance - not to be replicated in OSMF" qui contient le lien vers un document, lui aussi rédigé en français et traduit en anglais, retraçant les graves soucis de gouvernance dans le board de HOT US Inc pendant la période durant laquelle j'en étais membre (mars 2014 à janvier 2016)

During the campaign for the 2017 elections on the board of the OSM, I spoke three times on the OSMF mailing list:

  • this first email in English in which I show the weak involvement of Heather Leson in OSM since 2011.

Dynamic manipulation of styles based on object values in libosmscout

sam 9 déc 2017 - 15:57

As just stated on the Fossgis Hackingweekend at the Linuxhotel in Essen... "I'm mapping the year of constrcution for a (huge) number of houses. I'm looking for a way to visualize this on the map".

Likely multiple solutions exist, but how to do this with libosmscout?

At the start of the weekend this was not yet possible. Small discussion with another developer (not at the weekend) showed, that a general approach was needed, as colouring of ways based on attributes has also interesting use cases (hint: colour of metro lines).

Libosmscout implements tag and value combinations as features. All possible features of an object type (configurable during import) are flag in a bit set, if an concrete object has the feature.

The value of an feature is implemented as simple class that must offer serialization and deserialization methods.

So first we write a new Feature implementation that parses the start_date and year_of_construction tags. The new Feature will have two int attribute for the start and end year. Investigation of the actual tag values show and creation time can be an time interval, for our needs the year however is enough. Depending on the use case other implementation could be possible, too.

We need to do some string parsing to get most of the possible variants of the tag values parsed. Mapper: Please do not be to creative ;-)

Afterwards we add the possibility to register style processors into the rendering pipeline. The processor has a simple interface. It gets the list of feature values and the style as defined by the style sheet. It returns either the original style or a (cache) new style instance. Processors are registered by type.

Next step is to implement a simple processor for the type building. The processor checks if the construction year feature is available and the year between 1800 and 2020. In this case it return a red fill style, with the actual brightness depending on the age. Older buildings get darker red.

See the result:

Since there are not that much buildings with construction year mapped, let us try something more visible. Different colors depending on the house number been odd even (or not numerical).

Now that looks more obvious :-)

Fine. That was fun. Now back to code to refactor it for a slightly better API...
