Calling mappers from Porto

Hi everyone, I'll be visiting Porto in two days. Portugal is great, not as cold as Saint-Petersburg. We've already been to Lisboa, from where we recorded a holiday OSM podcast: English parts start at 2:00:30 (featuring Manuel Hohmann, Thomas "malenki" and Jerry Clough) and 3:01:15 (with Ian Lopez). The next issue will be recorded on 7th, 20:00-21:00 WET, and I very much hope to

Hi everyone, I'll be visiting Porto in two days. Portugal is great, not as cold as Saint-Petersburg. We've already been to Lisboa, from where we recorded a holiday OSM podcast: English parts start at 2:00:30 (featuring Manuel Hohmann, Thomas "malenki" and Jerry Clough) and 3:01:15 (with Ian Lopez). The next issue will be recorded on 7th, 20:00-21:00 WET, and I very much hope to talk with a local, portugese mapper. Maybe even face to face, though usually I use Skype or Mumble.

So, if you map Portugal, or live in Portugal, or know someone from Portugal — contact me please. Also, I'm up for a osmers meeting in a cafe near Santo Ildefonso on 7th or 8th. I'm Ilya, my phone (for sms only) is +7 921 583-12-91.


CLC06 Import Cleanup

When I first got involved in OpenStreetMap all my mapping was done in the iD editor, a great user experience for new users easy to work with and tagging made easy. My first experience with iD and OSM was terrible. It was because of a old low quality forest import that covers a huge area, shown below.

Most of the import is two massive multipolygons with tons of relations. In iD

When I first got involved in OpenStreetMap all my mapping was done in the iD editor, a great user experience for new users easy to work with and tagging made easy. My first experience with iD and OSM was terrible. It was because of a old low quality forest import that covers a huge area, shown below.

OSM screenshot

Most of the import is two massive multipolygons with tons of relations. In iD it was impossible to merge other areas into the multipolygons and the forests had to be heavily remapped. The result of other mappers ways to deal deal with this has lead to two massive multipolygons with broken relations, resulting in rendering issues. First image below shows the quality of the import, the second shows a rendering issue in iD as a result of broken relations(Not related to the reverse inner bug).

JSOM screenshot.

rendering issue in iD.

Below is two screenshots from Overpass Turbo, showing how the imported data looks like in the OSM database. The first image shows both ways and relations, the second just shows relations(multipolygons).

Ways and relations.

Relations

The imported multipolygons has become a issue to the OSM ecosystem. It makes it hard for developers and designers to use the data because applications such as Tilemill and Mapbox Studio having rendering issues with the data. It becomes a issue for new mappers that has to remap major areas(in iD this means dragging nodes), that can't merge smaller areas such as lakes and has to deal with relations.

I'm looking into solutions for splitting the two major multipolygons into pieces along major roads(they should be it anyway) or in a worst case scenario delete them. If anyone has a idea about how we should deal with this please share your knowledge.

There is other imports like this one in Sweden some of them also from EEA Corine Land Cover 06(Link to latest version of the dataset) but I haven't looked into them as much. I think that we need forest imports at least here but we need to be able to work with them from or usual tools such as JSOM and iD.

Any thoughts?

HOT 2014 Year in Review

I started my HOT year a worried president of the HOT Board, and ended as a confident regular member.

I started my HOT year a worried president of the HOT Board, and ended as a confident regular member.

We all worked hard. Really hard. Most importantly on HOT activations and projects. HOT has had a stunning impact on humanitarian response. But we knew we could this. What challenged us more was ourselves. We worked hard on HOT's organization, the processes and relationships that make the space for amazing to happen.

Ok, let me just say personally, I had a lot to learn this year. I'm not proud of everything I did. But I'm immensely proud of where HOT is now.

The Board Face to Face was a real turning point. Sincere thanks to the Board for putting our all into this. And thanks to our guide Gunner.

Some other things I spent time on: helped coordinate to get V2 of the OSM Tasking Manager developed; formalized imagery coodrination; put together trademark applications for HOT; formally employed our Executive Director.

I joined the US government for a year, and really just getting started. My HOT 2015 orbits around this. Since I'm no longer on the Board, I'll have more time to put into working groups, community building, technology.

HOT/OpenStreetMap 2015 Aspirations

In follow-up to my last post: HOT 2014 Review, here is a brief post regarding my aspirations for 2015.

In follow-up to my last post: HOT 2014 Review, here is a brief post regarding my aspirations for 2015.

Continued contribution to mapping

  • I'd like to increase my HOT mapping activities throughout 2015, contributing to more projects, and contributing more significant task content in those projects.
  • Continued and increased contribution to global mapping in areas with low map detail but sufficient imagery to contribute. I've previously contributed significantly in Ghana and Burma and i'd like to keep up these contributions and engage with local mappers to offer assistance.

Assisting with new mapping techniques

  • Enhancing before/after intelligence to HOT tasks. This could be useful for tasks in places like Gaza where there is focus on mapping change over a period of time (i.e. before & after the bombing of 2014)
  • Automated feature extraction & change detection with visual checking steps. Viewed by many as an unattainable goal for OSM, but i believe there can be a certain level to be gained in OSM by these techniques. This will most likely involve Python and JavaScript libraries to create some kind of prototypical solution.

Community involvement

  • Engage and assist newbie mappers in Ghana. I did some of this a few years ago, but would like to get involved again and offer any assistance i can.
  • OSM Events & Conferences. I'd like to make it to and potentially present at a variety of events this year including SOTM, GeoMob, OSM London etc..

Happy New Year and good luck mapping,

Greetings, this is a brief recap of my contributions to the Humanitarian OpenStreetMap Team (HOT) in 2014.

HOT Community Relations

HOT emails over the last 18 months have become quite counter-productive and personal. I feel as though we have lost our way as a constructive contributory community. For that reason i have stopped reading them, it has also affected how much i interact with the community and alarmingly how much i contribute to HOT mapping tasks. I'd like this community to be a bit more constructive and work together. For my part, i will not create unnecessary noise on shared communication channels and attempt to set an example by chipping away at a few areas i feel i can add value to.

HOT Mapping Contributions

Reduced involvement in HOT

Over the last two years i have been less involved in HOT due to a number of factors

  1. I was somewhat disenchanted by the membership process within HOT, i felt a lot of the organisation around members and voting went some way to making it a less inclusive closed group - which was a big attraction when i first started mapping for HOT during the Haiti Earthquake.
  2. Having a 1 year old child
  3. Increased pressures and responsibility in my professional career. Ironically i have been working on a large mapping task management system for government and i was able to use some of the ideas from HOT and the tasking manager to achieve this goal.

Regrettably i was unable to contribute to any Ebola mapping tasks in West Africa as i had sever pressures on my time throughout most of this year although i would have loved to contribute and i'll continue to push myself to make at least a minor mapping effort in the future.

Sincerely,

Sam Larsen

Voting is bullshit

On of my professor at university quite often told us that "Marketing is bullshit". He reasoned that marketing never tells you the whole truth. I guess everyone who ever watched an ad or read some marketing brochure tends to agree with him - except marketeers, of course.

On of my professor at university quite often told us that "Marketing is bullshit". He reasoned that marketing never tells you the whole truth. I guess everyone who ever watched an ad or read some marketing brochure tends to agree with him - except marketeers, of course.

Voting in OSM

What does this have to do with voting in OSM? The result of a vote has the same problem as marketing: it never tells you the whole truth. Ten, maybe twenty, sometimes even thirty hardcore mailing list and wiki writers gave their vote and decided for the rest of humanity, what to do and what not to do. But are those who voted really the ones who actually improve our data?

What if Joe Mapper thinks, that the approved tag does not fit his needs and he uses a different tag? We have an approved proposal, so we can replace his tag with the approved one - right? What if Joe Mapper proposed something and it was rejected, but he still uses the proposed tags? They were rejected so lets delete them - right?

No.

Our core values

The foundation of OSM is that everyone can use every tags they like. No approval needed. Just don't provide incorrect data or destroy others work. Lets have a look at the core values of OSM: Do-ocracy, Actions speak louder than words, without need for central sanction or even post-hoc approval.

I guess, that's pretty clear. If no one needs an approval, why do we ... sorry, I meant... why does a very limited number of people vote? If an approval is not necessary, why does something have to be approved?

Isn't voting itself against our core values?

Data consumers

It seems obvious to me why proposal-writing and voting-ecstasy got a little out of control: data consumers.

All our data is completely worthless without someone processing it: drawing some nice maps, leading us our way and much more. And data consumers need clear definition: this tag means this and that tag means that. So they want approval: this tag is "good" (as in "approved") and this is "bad" (as in "not approved" or even worse: "rejected"). If everything is clearly defined, it is easier to process our data. But there is one thing, that is quite often forgotten:

You can not process voting results.

Clarification added at 21:00 CET 04.01.2015: In my opinion the pressure comes from the data consumers, but not only directly. Sometimes mappers want something supported in their favorite application and they think that all they need is some "official" and "approved" tag. Gladly this is not true.

Back to do-ocracy

Clear definitions about how our data can be interpreted are in the interest of all. But those definitions should not be approved, they should evolve. If we approved a tagging scheme and no one uses it, it is useless. If it is used, but completely inconsistent, because it is too complex, it is useless.

We should not vote on new tagging schemes, we should support them - or not.

Lets replace voting in our proposals by usage numbers like taginfo and a list of supporters (mappers and consumers). No rejecters. If you don't like the proposal write your own, convince others to use it and try to get some support from data consumers. Adapt it from time to time, if necessary. And after a while look at the usage numbers and the number of supporting consumers.

Let the numbers do the voting.

P.S: No, I will not put that proposal up for a vote.

A look at Scout Signs

Hi,

I've had a look at Scout Signs. I agree that this is a comfortable way to collect maxspeed data. What I've compared in my region leads me to the following conclusions:

Here the email I just sent to Scout/Skobbler:

Hi,

I've had a look at Scout Signs. I agree that this is a comfortable way to collect maxspeed data. What I've compared in my region leads me to the following conclusions:

  • the average Scout Sign I verified is misplaced by averagely 20 m¹
  • all of the speed limits shown by Scout Sign I verified were already mapped in OSM
    –> I'd find it helpful to only show signs in JOSM for highways without maxspeed=* or maxspeed:forward/backward or where the by Scout collected maxspeed doesn't match the one on the highway
    –> because: after closing a lot of Scout Signs with "it is already in OSM since 1-4 years" the task gets boring
  • the OCR seems not to be failsafe: alt text (Sign ID 25587, here)

I would welcome if discussions regarding this plugin would happen in the public, but regrettably there is neither a page for the plugin in the OSM Wiki nor is it mentioned there nor is there the possibility to discuss it at the place where you introduce the plugin.

Additionally it would be very useful to provide a link with the plugin to be able to learn just something about it. Scout Signs is one of only some plugins not providing any additional informations on plugin list: alt text

Best regards
Thomas

(I sent a second email with this content):
PS: the following would enhance the workflow and usability, too:

  • ability to click on the Scout Signs from the acitve data layer (atm one has to switch to the Scout Sign layer to can do that)
  • hide solved/invalid Scout Signs (or at least show them in a different style)

Mapeo Bardenas Reales de Navarra.

Primera entrada en el diario :).

Bueno, he acabado de mapear las Bardenas Reales, al menos lo que he podido apreciar por ortofoto, así que dejo unas notas para que otros usuarios mejoren lo hecho.

Primera entrada en el diario :).

Bueno, he acabado de mapear las Bardenas Reales, al menos lo que he podido apreciar por ortofoto, así que dejo unas notas para que otros usuarios mejoren lo hecho.

  1. Mi experiencia física en las Bardenas Reales se reduce a ir de Arguedas al Castiltierra, dar la vuelta al polígono de tiro, y volver a Arguedas, creo que por el mismo camino, todo ello en coche... Por tanto, el mapeo se ha basado sobre todo en ortofotos del PNOA y de Bing, en el mapa de calor de Strava, y en las pistas GPX subidas por los usuarios. En algún caso he buscado fotos por Internet para cotejar el estado de alguna vía, ante la imposibilidad física de ir allí XDD.

  2. El mapeo lo he hecho de norte a sur, primero indicando únicamente las pistas y caminos, más adelante las construcciones, y más adelante los accidentes geográficos, como canales, aguas de escorrentía, y estanques, según fui soltándome, jajaj. Por tanto, es muy probable que por el norte haya construcciones sin mapear, y por el norte y el centro varios accidentes geográficos sin indicar. No he agregado ningún cauce de aguas de escorrentía, porque si empiezo con ellas, no acabo en la vida...

  3. Cuando alguna pista o camino seguía su trazado saliendo de los límites de las Bardenas, he procurado continuar el dibujado hasta encontrarme con otra vía, estuviera donde estuviese; por tanto, en los límites exteriores del parque hay pistas mapeadas y pistas sin mapear, y la razón es esa, en lo que concierne a mis contribuciones. En otra ocasión intentaré mapear esos otros caminos que faltan, pero tengo que ponerme un límite antes de empezar, porque si no, comienzas, pero no sabes cuando acabas.

  4. No he mapeado nada en el interior del polígono de tiro.

  5. No he mapeado nada en el interior de Senda Viva.

  6. He detenido el mapeo de caminos cuando se llegaba a un campo de cereales, aún viendo por ortofoto que dentro del mismo campo se distinguía perfectamente una vía. Esto es así porque no sé, básicamente, si se puede pasar alegremente por esos campos, supongo que no, así que por si acaso, no los pongo. Los únicos casos donde sí los he trazado es donde veía a través del mapa de calor de Strava que es una ruta más o menos concurrida, así que puedo suponer que se puede pasar. Hago notar que no he apreciado ningún tipo de barrera en los accesos a los campos, aunque por ortofoto es difícil...

  7. Aunque no he agregado ningún cauce de aguas de escorrentía, sí he ajustado algunos de los existentes, básicamente porque su trazado no coincidía con las ortofotos; he ajustado el trazado a las zonas por donde aparentemente circula el agua en época de lluvias; todos los puntos donde se cruzan con caminos, los he marcado con vados o puentes, según sea el caso.

  8. Hacia el sur he agregado los generadores eólicos.

  9. He corregido el trazado de varios caminos que se desviaban en varias decenas de metros del trazado mostrado por ortofoto.

  10. He hecho caso al JOSM cuando me decía que el indicador del tipo de bosque estaba obsoleto.

Seguro que me queda alguna puntualización más por hacer, pero bueno, ya llevo un tocho considerable :). Cualquier cosa para ayudar en la mejora del mapa será bienvenida.

Un saludo.

Introduction

Since five years Guy Roman is retired. Before that he was technical electrician for a engineering company. He mainly followed up projects for energy distribution and automation. So he was already "drawing" during his career.

How and when did you discover OpenStreetMap?

I accidentally discovered OpenStreetMap in 2008.

What kind of mapper are you and where are you mapping?

I map a lot, mainly in Hainaut, a province in Belgium, but I also map abroad. Partly based on trips I make during my vacations, but I also base my mapping on photos that appeal to me. An example is a photo of St Rambert-en-Bugey in France that I found in a magazine about railways. I looked up the area in OpenStreetmap and then mapped it based on the picture and Bing arial images.

What do you map and do you have any specialisation?

I mainly use the aerial images from Bing, but I combine this with the available GPS traces for ways that are invisible on Bing, e.g. in forests. Further I also do surveys, to determine the type of the roads for example. Quite regularly I go cycling 50 or 70 kilometers, where I verify my database of geographical data and if necessary I change things on OpenStreetMap.

Why do you map?

It is fun, and it allows me to explore the world without leaving my house!

Guy's contributions Guy's contributions

Do you do other things related to OpenStreetMap?

I try to convince possible "passive" users to use OpenStreetMap, such as organisers of hiking trips.

How can OpenStreetMap be improved?

I hope that the rendering of some details can be improved on the default map. An example are areas tagged as "natural=scree" for example near mountain rivers. It could be rendered similarly to beaches, but in grey. Another example: it would be nice to have a rendering for a stream on a bridge. At this moment it is only possible for a canal. Unfortunately I do not have enough knowledge to help out to improve this.

To conclude, is there something else you want to share with the readers?

Only change an object when you are sure that it will be more precise or closer to reality than the current version. Also, when you have doubts about something, please contact the previous mapper to ask more details about the current mapping! Furthermore, please respect the classification of the roads. The classification of a road does not suddenly change to residential, because there are few houses.

Seit 1984 treffen sich jährlich Kreative zum Ende des Jahres, um am Chaos Communication Congress teilzunehmen. Zwischen dem 27. und dem 30. Dezember 2014 fanden sich über 10000 Menschen aus aller Welt im Congress Center Hamburg ein, um sich mit gleich- und andersgesinnten auszutauschen, Vorträgen zuzuhören oder an Projekten zu arbeiten.

Bei einer solchen Veranstaltung darf die OSM Außenstelle natürlich nicht fehlen. Wir führten die Tradition eines OSM-Standes weiter, insbesondere nach der tollen Resonanz des letzten Jahres. An Tag 0 bereiteten wir unseren Platz vor, am ersten Tag der Veranstaltung rückte dann auch verschiedenstes Werbematerial nach und wir zeigten uns mit diversen Karten, Flyern, einem Großformatdrucker und einem Präsentationsbildschirm, auf dem wir zumeist Show Me The Way laufen ließen. Besonders letzteres zeigt sich immer wieder als Publikumsmagnet, der dazu führt, das Vorbeigehende wie hypnotisiert vor dem Bildschirm stehen bleiben und sich schnell diverse Fragen aufwerfen. Dank der großartigen Standcrew (vielen Dank insbesondere an tirkon, Nakaner, Kolossos, The Five, ubahnverleih, Michael und Marc) haben wir fast alle Fragen beantworten können.

Besonders freute mich die Annahme des Vortrags "10 Jahre OpenStreetMap" ins Programm, den ich zusammen mit Consti hielt. Wir versuchten einen möglichst breiten Überblick zu schaffen und wie immer mehr Aufmerksamkeit für unser Projekt herzustellen. Aus diesem Grund freute uns besonders, dass Medien wie Netzpolitik.org oder das größte deutsche iPhone Blog iphone-ticker.org darüber berichteten.

Wir ließen keine Gelegenheit aus, um zum Mitmachen bei OSM aufzurufen. Insbesondere die Möglichkeit zur Fehlermeldung haben wir häufig als niedrigschwelligen Einstieg empfohlen. Leider gibt es trotz vieler Androiduser immer noch keinen zufriedenstellenden Editor für Einsteiger. Wir hoffen auf Besserung und ich befinde mich bereits im Austausch mit Entwicklern, die daran interessiert sind, uns weiterzuhelfen. Wie wir schon im Talk erwähnten, hoffen wir insgesamt auf mehr Mikroeditoren, die Änderungen in OSM abstrahieren und komplizierte Aufgaben in einfach bedienbare UIs umsetzen.

Sehr gut fanden wir das Konzept der "self-organized sessions", welches uns ermöglichte, spontan Workshops zu organisieren. Nakaner leitete einen einstündigen Workshop "Mapping für Einsteiger", in dem er Grundlagen erklärte und vom unübersichtlichen Wiki verwirrten Menschen auf die Sprünge half. Für Freunde der Datenverarbeitung habe ich zwei Workshops (Deutsch und Englisch) gehalten, in denen ich über technische Grundlagen gesprochen habe und diese mit Overpass Turbo demonstrierte. Die gut besuchten Sessions verliefen interaktiv, sodass auf Fragen und Ideen gleich im größeren Kreis eingegangen werden konnte.

Aber auch im normalen Betrieb auf dem OSM-Stand konnten wir auf Besucher eingehen und weiter in die Tiefe gehen und interessanten Projekten weiterhelfen oder zum Start dieser beizutragen. Auf Konsumentenfragen versuchten wir auch immer möglichst gut einzugehen, ich musste jedoch feststellen, dass viele Apps usabilitytechnisch längst nicht gut sind und wir dort sehr viel tun müssen, damit eine Massenkompatibilität erreicht werden kann.

Für mich war es eine große Freude, dieser Veranstaltung beigewohnt und dazu beigetragen zu haben und ich möchte mich bei allen bedanken, die dabei waren und OSM würdig vertreten haben. Bis demnächst!

The yellow square shows the last of 5 cars parking in a space large enough for 3, it is not signed as a parking area.

The blue square shows a car parked in front of a garage, but what a direction? Breaking pattern?

The red square shows a car parked on the sidewalk, there where up to 6 cars parked like this during the day, and I counted a total of 20 cars parked like that.

Doesn't seem to help calling the police to remove illegal parked vehicles, they are too busy doing that 200 meters down the road (in front of the banks and restaurants), and politicians doesn't care much since these tourists are bringing in money to fill their pockets.

Map tiles are delivered to users based on their GeoDNS location. The OpenStreetMap tile content delivery network (CDN) now supports EDNS-client-subnet to improve locating the closest region tile cache.

OpenStreetMap tiles are free for everyone to use, but should be used with moderation. If you are a high traffic site you should look into switch2osm.org to find out how to use the data and keep the tiles available for everyone.

Thanks to generous donations and active local community members, the OpenStreetMap distributed tile delivery infrastructure continues to grow.

The OpenStreetMap Foundation seeks additional distributed tile servers. If you would like to donate a tile server and hosting, please see the Tile CDN requirements page on the wiki. You can also support OpenStreetMap by donating to the OpenStreetMap Foundation.

The OpenStreetMap Foundation is a not-for-profit organization, formed in the UK to support the OpenStreetMap Project. It is dedicated to encouraging the growth, development and distribution of free geospatial data and to providing geospatial data for anyone to use and share. The OpenStreetMap Foundation owns and maintains the infrastructure of the OpenStreetMap project.

We’re thrilled to welcome Lyzi to the Mapbox team! As a co-founder of the geo education-focused Maptime meetup series and a longtime OpenStreetMap contributor, we have no doubt she’ll continue to stir up the geo space and with her energy for teaching and building. Previously, Lyzi was a Code for America Fellow with the City of Lexington, Kentucky and got her hands dirty with GIS and cartography at the Oregon Department of Geology and Mineral Industries (DOGAMI). At Mapbox, she’ll write documentation and tutorials and generally make Mapbox tools easier to use.

Say hello to Lyzi and ask her about getting started making maps, how to get involved with Maptime in your city, or her obsessive love of Oregon Ducks football.

London Wall/Museum of London roundabout changes only protect left turning cyclists

A week ago I was cycling along London Wall and past the Museum of London roundabout, and noticed some changes with paint and traffic cones. As you arrive at the roundabout you choose which side of the cones to go on depending on whether you are turning left or taking the straight on or right exit. Left turn cyclists are given protection by the paint and traffic cones, whilst the straight on or right turn cyclists are mixing with motor vehicles.

Then on the roundabout left turn cyclists are expected to give way to other cyclists coming round the roundabout as they about to exit the roundabout. Are these give way lines really needed? Can’t cyclists nicely merge together without needing to have priorities like motor vehicles require? There is enough space to have 2 cyclists side by side without impacting motor vehicle traffic, thus this shouldn’t be an issue.

Most importantly I’d like to question why cyclists who are not turning left are expected to mix with motor traffic? This is not going to help encourage inexperienced cyclists to use the roundabout. Will the cones stay there long term? Or will the cones be removed with motor vehicle drivers simply ignoring the white paint? Could drivers complain at cyclists going straight on or turning right for not using the cycling facility (i.e. being to the left of the cones/paint)?

Why not follow the tried and tested Dutch designs for roundabouts since there’s plenty of space? Both David Hembrow and Mark from Bicycle Dutch have blog posts explaining Dutch roundabouts, thus I won’t go into detail here.
