RicoElectrico wertet ähnlich geschriebene Straßennamen in Deutschland aus 1 | Map Style uMap CC-BY-SA licence 2.0 | Kartendaten © OpenStreetMap-Mitwirkende

In eigener Sache

  • In unserer letzten Ausgabe haben wir über die frei werdenden Posten im OSMF-Vorstand berichtet. Wir möchten nachreichen, dass nicht drei, sondern vier Posten zur Wahl stehen werden. Heather Leson zieht sich vor Ende ihrer Amtsperiode aus dem Vorstand zurück.

Mapping

  • OpenStreetMap Guinea kündigt in einem Tweet (fr) die Sammlung von Daten über wilde Deponien in der Gemeinde Ratoma in Conakry an, die auf einer uMap-Karte visualisiert werden.
  • Ruben schlägt vor, die Erfassung von Öffnungszeiten um einen Wert für „nach Vereinbarung“ (opening_hours=appointment) zu erweitern.
  • Jeremiah Rose schlägt footway=indoor vor, um Indoor-Routen innerhalb von Gebäuden zu markieren, die mit Simple Indoor Tagging erfasst sind, hat aber die Unterscheidung zum bestehenden highway=corridor noch nicht erläutert.
  • Andrew vom Apple Maps Team hat potenzielle Probleme mit Straßen und Routen in Angola, Ägypten, Kenia, Ruanda, Südafrika, Tunesien und Uganda zu MapRoulette hochgeladen.
  • SK53 versucht, das Tagging für Showgrounds zu vereinheitlichen und listet die verschiedenen inkonsistenten Ansätze, die er in Großbritannien fand, auf.
  • Die Diskussion darüber, wieviel lanes= eine Straße ohne Markierungen hat, ist nicht neu. Ein Artikel in der Zeit liefert jetzt Argumente für die Mapper, die die Breite einer unmarkierten Straße als Indikator für die Anzahl nutzen.
  • Lyft, ein On-Demand-Transportunternehmen mit Sitz in San Francisco, USA, berichtet über seine Bemühungen, Kartenfehler in OSM zu erkennen, zu melden und zu beheben.
  • Studenten der Miami University und Fachleute für geografische Informationssysteme (GIS) haben einen „Bahamas Mapathon“ gestartet, um dem Inselstaat nach dem verheerenden Hurrikan Dorian zu helfen.
  • [1] RicoElectrico wertet ähnlich geschriebene Straßennamen in Deutschland aus, die nahe beieinander liegen, z. B. Mainzer Strasse vs. Mainzer Straße. Dies deutet häufig auf Tagging-Fehler hin. Wulf4096 erstellt hieraus mittels umap eine Karte. Von ursprünglich 1376 (möglichen) Fehlern wurden 274 bereits korrigiert.

Community

  • Die irische OSM-Community hat einen Antrag gestellt, ein lokales OSMF-Chapter für Mapper in beiden Teilen von Irland, der Republik Irland und Nordirland, zu werden. Alle, mit einer Ausnahme, begrüßen die Idee eines lokalen Chapters für Mapper aus zwei Ländern.
  • Die Stadt Köln sucht ab sofort einen ausgebildeten Geomatiker oder Kartografen (m/w/d) in Vollzeit mit Affinität zu OpenStreetMap.

Importe

  • Brian M. Sperlongano würde gerne die Grenzen der Census-designated places auf Hawaii importieren. Es gibt jedoch Unklarheiten über das Tagging, da CDPs nicht den Kriterien für boundary=administrativeentsprechen.
  • Auf der SotM US 2019 demonstriert Facebook seine Bildverarbeitungssoftware, um Gebäude mit RapiD in OSM zu importieren.

OpenStreetMap Foundation

  • Nuno Caldeira ist bei Facebook-Karten ein neuer Knopf aufgefallen, mit dem man Kartenfehler melden kann. Leider musste er feststellen, dass dabei kein OSM-Hinweis geöffnet wird. Nuno hatte die unkorrekte Kennzeichnung bereits vor einem Jahr bei Facebook gemeldet und vor drei Monaten die OSM Foundation gebeten Facebook zu einer korrekten Attributierung zu bewegen.
  • Die Markenpolitik der OSMF ist immer noch ein Thema, das auf der Mailingliste diskutiert wird, und nicht jeder ist mit dem aktuellen Verfahren zufrieden.
  • Michael Reichert erinnert daran, die Mitgliedschaft in der OpenStreetMap Foundation zu verlängern und ruft alle anderen dazu auf, Mitglied in der Foundation zu werden. Sie solle für jeden, der für OSM brenne, eine Ehrensache sein.

Veranstaltungen

  • Die Tickets zur diesjährigen State of the Map Konferenz sind seit dem 6. September ausverkauft. Für alle, die kein Ticket mehr bekommen haben, gibt es die Livestreams und VoD-Aufnahmen, später dann abrufbar über die Programmseite.
  • Die Initiative Einfachbahn veranstaltete am 12. September eine Mappingparty in Frankfurt am Main. In zwei Gruppen wurden das Erfassen von bahnbezogenen Geodaten in den Bahnhöfen Frankfurt-Höchst und Frankfurt-Rödelheim geübt und anschließend mit JOSM editiert. Über das Kartieren hinaus fand ein reger Informationsaustausch über Bahn-Geodaten statt.
  • Die FOSS4G SotM Oceania sucht einen Gastgeber für die Veranstaltung im nächsten Jahr.
  • Der nächste grenzüberschreitende Stammtisch DE-FR findet am 28. September wiederum in Straßburg statt.
  • Der SigInfoLibre-Blog (fr) (automatische Übersetzung) berichtet über den teilregionalen Workshop für Leiter von OpenStreetMap-Communities im französischsprachigen Afrika. Der Workshop findet an der Universität Lomé in Togo, mit Unterstützung der Organisation internationale de la Francophonie, statt. Auf der Tagesordnung sprechen die Teilnehmer über OpenStreetMap Management, Projektentwicklung, Kommunikationstechniken und freie digitale Kartierungstechniken.
  • Oft wird Rapperswill, Schweiz im Kontext innovativer OSM-Technik und -Anwendungen genannt. Es ist daher zu begrüßen, dass sich Rapperswill für die Ausrichtung der nächsten State of the Map-Konferenz vom 19. bis 21. Juni bewirbt.
  • Die FOSSGIS 2020, das jährliche Treffen für Open Source Geo-Software und OpenStreetMap in Deutschland, findet vom 11. bis 14. März in Freiburg statt. Wie gewöhnlich ist der letzte Tag immer ein Samstag und nur für OSM vorgesehen.
  • Missing Maps organisiert einen weiteren Mapathon in den Büros von Ärzte ohne Grenzen in Brüssel. Die Veranstaltung „Save the World – Map it“ findet am 24. September statt.
  • Ilya Zverev berichtet von der SotM-US – Mittwoch (automatische Übersetzung) – Donnerstag (automatische Übersetzung) – Freitag (automatische Übersetzung). (ru)

Ausbildung/Schulung

  • Die französische Nichtregierungsorganisation CartONG, die Kartierungs- und damit verbundene Dienstleistungen für humanitäre und Entwicklungsorganisationen anbietet, bietet eine offene Position als Data Specialist in Chambéry, Frankreich an.

switch2OSM

  • Severin Kann meldete über Twitter, dass in Krakau, Polen OpenStreetMap in den Trams zur Echtzeit-Positionsanzeige verwendet wird.

Open-Data

  • Mitfahr|de|zentrale hat den kürzlich veröffentlichten Datensatz von ÖPNV-Haltestellen-Daten für Baden-Württemberg von NVBW mit OpenStreetMap-Daten verglichen.

Programme

  • Development Seed kündigte die Einführung von mapping.team an, einem Tool zur Mapping-Koordination und Aufbau von Communities. Der Blogbeitrag bietet einen umfassenden Überblick und regt an, die Beta-Version zu testen, eine eigene Instanz zu erstellen oder Code zu dem GitHub gehosteten Projekt beizutragen.
  • Simon Poole hat eine Feature-Vorschau der nächsten Version des Vespucci-Editors für Android erstellt. Die erste Beta von Vespucci 14 wird wahrscheinlich noch im September starten.

Releases

  • OsmAnd gab die Veröffentlichung der Version 3.0 seiner iOS App bekannt. Die neue Version bietet eine Schnellaktionsfunktion für den Zugriff auf verschiedene Kartenaktionen über den Startbildschirm, die Möglichkeit, eine fehlende Regionskarte direkt aus dem Kontextmenü herunterzuladen, sowie Hinweise zu Tags und Werten auf dem erweiterten OpenStreetMap-Bearbeitungsbildschirm.

Kennst du schon …

  • …. die Mailingliste OSM-Science?
  • … die beiden Arten von gasbetriebenen Fahrzeugen? Es gibt Autogas (verflüssigtes Gas, fuel:lpg) und komprimiertes Erdgas (fuel:cng). Beide sind nicht kompatibel zueinander und sollten deswegen beim Taggen von Tankstellen auch nicht verwechselt werden.

OSM in der Presse

  • LinuxInsider berichtet über die neue OSGeoLive-Version, vorgestellt auf der FOSS4G in Bukarest. OSGeoLive ist eine Linux-Distribution, die sich auf geografische Anwendungen spezialisiert hat. Es finden sich viele GIS und OSM Anwendungen wieder.
  • MKnight hat im deutschen OSM-Forum einen neuen Thread namens „OSM in Funk und Fernsehen“ geöffnet. Im ersten dort genannten Video, das sich mit dem deutschen Schilderwald befasst, wird OSM im Vergleich zu Google Maps positiv hervorgehoben.

Weitere Themen mit Geo-Bezug

  • Das MapTiler Team stellt seine Präsenz auf der FOSS4G in Bukarest vor.
  • Ciclo bringt ein neues, besonders großes (4 Zoll Display), Fahrrad- und Wander-Navi heraus, das CicloNavic 400. OSM-Karten (Westeuropa) sind vorinstalliert.
  • Elijah Zarlin von Mapbox stellt 15 spannende Projekte vor, die in letzter Zeit mit den Mapbox-Tools entstanden sind.
  • The Pudding haben eine People Map der USA erstellt, auf der die Städtenamen durch die Namen ihrer Bewohner in Wikipedia’ed ersetzt werden. Es gibt auch ein Großbritannien für diejenigen, die es vorziehen, die andere Seite des Atlantiks zu sehen.
  • Heise online berichtet über einen Rechtsstreit zwischen Niantic und Privatpersonen. Diese fühlten sich von Pokémon Go Spielern belästigt, die ihre Grundstücke betraten. Pokéstops sollen nun nicht mehr unmittelbar an Einfamilienhäusern platziert werden. Pokémon Go basiert seit Ende 2017 auf OpenStreetMap Daten.
  • Dass Pokémon-GO-Spieler gerne mal für Kontroversen in der OSM-Community sorgen, ist nichts Neues. Aber es geht auch anders herum: The Silph Road zeigt, dass einige OSM-Tags dafür sorgen, dass im Spiel in bestimmten Gebieten keine Pokémon spawnen. Natürlich liegt das nicht an OSM selbst, sondern an der Verarbeitung der Daten.
  • Google Maps bindet beim ÖPNV-Routing nun auch Ridesharing-Angebote „für die erste und letzte Meile“ mit ein, um noch mehr Fußwege zu sparen.
  • Das nordamerikanische Datum von 1983 ist der Everest der klassischen Vermessungskunst, der kurz vor der Revolution der Satellitengeodäsie abgeschlossen wurde. Tim Burch diskutiert die vier plattenfixierten terrestrischen Bezugsrahmen, die 2022 das ehrwürdige NAD83 ersetzen werden. Eine Kombination aus der Korrektur des 2m Versatzes von NAD83 vom Geocenter und dem Absenken des US-Messschiebers und der Übernahme des internationalen Fußes wird einige Punkte anscheinend um bis zu 4m verschieben.

OpenStreetMap User's Diaries

So I completed a PhD on community engagement in HOT and Missing Maps...

… two years ago, and I haven’t even managed to write a diary entry about it. Has it really been that long? I’ve been meaning to post a summary for the longest time, but somehow life got in the way. Fortunately, this week David Garcia and me will host a workshop at the HOT Summit and present a talk at State of the Map in Heidelberg. I’m super excited about both sessions – you should join us if you’re coming! And it became the perfect excuse to dust off my draft for this post, and make sure all the research outcomes are finally assembled in one place.

But let me start in the beginning.

Hallo, my name is Martin Dittus, and between 2014 and 2017 I’ve accompanied HOT and Missing Maps for my PhD on community engagement in humanitarian mapping. We’ve had an amazing time together! During the PhD, we were trying to understand how best to build HOT volunteer capacity online and offline. How can we best train our volunteers so that they are available when needed? What kinds of support can we give them to ensure they don’t drop out early? And the age-old question: are the most highly engaged contributors “born or made”?

HOT’s diversity of settings provided excellent opportunities to observe the outcomes of different coordination practices. The research was largely quantitative and observational, using data in the full OSM contribution history and the HOT tasking manager, combined with a lot of prep work to understand the nuances. This was very much a collaborative effort and a real partnership with quite a few groups and individuals in the OSM and HOT community, and the evaluations were always informed by real concerns in the community. I was blessed to find an incredibly active community in London, and made some great friends along the way. It made a massive difference that early on I met Pete Masters and Andrew Braye who then connected me to many others in the vast global network of enthusiasts and experts that is HOT. In addition to looking for answers to pressing organiser issues, we revisited some existing theories in social and behavioural science in the context of HOT, using statistical methods to analyse contribution activity across multiple years of HOT’s edit history.

We could demonstrate that coordination practices can have a marked impact on volunteer activity and retention, and the work has already achieved quite some impact within and beyond HOT. I’ve been using this OSM diary to document my research progress since 2015. Over time this has lead to significant debate and reflection within the HOT community, and on more than one occasion it has informed specific changes in organiser practice. In addition, four studies have been published in major academic venues, and two of them have received awards. We couldn’t have done any of this without a lot of community support!

Publications

If you’re curious you can read my full dissertation here: Analysing Volunteer Engagement in Humanitarian Crowdmapping (PDF). However I don’t expect many would want to read it in full, so for the impatient it may suffice to read the abstract on page 5, and the concluding summary chapter from page 151, in particular the summary of findings from page 153. (This by the way is often the best way to read academic papers: read the abstract to see if you like the paper, then read the conclusion to get the summary. You could then read the full paper if you’re still curious about the details.) The very impatient can get a 1-minute summary below.

The bulk of the thesis simply reproduces four papers that were published during the PhD, you can also get those separately. They’ve already been discussed in this diary in various forms, typically while the work was still in progress. It’s interesting to revisit the work now with some distance – you can really see a progression in the quality of execution. The papers are, in order of publication:

Analysing volunteer engagement in humanitarian mapping: building contributor communities at large scale (PDF). This is maybe quite a rough paper in terms of the quality of execution, but to this day it’s somehow the most widely cited one. Likely because it was one of the few quantitative studies of HOT at the time. I now think of it as an early exploratory study that establishes some basic concerns. A key finding: maybe unsurprisingly, it appears that complex task designs can be discouraging to newcomers.

Social Contribution Settings and Newcomer Retention in Humanitarian Crowd Mapping (PDF), where we investigate the role of mapathons as attractors for new and existing volunteers. This one was quite hard to complete, took longer than expected, and the findings were a bit underwhelming… quantitative methods are useful for certain things, but I think for a real evaluation of mapathon settings a qualitative research approach is likely more powerful. Broadly we found that attendees at one-off events at “corporate” mapathons were often quite committed during the duration of an event, but unlikely to keep mapping afterwards. By comparison, the monthly rhythm of the public Missing Maps mapathon appeared to foster more of a longer-term engagement.

Mass participation during emergency response: Event-centric crowdsourcing in humanitarian mapping (PDF). This paper is maybe my personal favourite. It only required some very basic statistics, but yielded some novel observations about the nature of community engagement in emergency response. We found that disaster response campaigns such as after the Nepal earthquake can be significant recruiting events, however that these newcomers might not stick around for very long… on the other hand, for many long-term contributors HOT engagement is very much characterised as a dormancy-reactivation cycle, responding to events as they happen rather than always mapping. Is this an opportunity to optimise HOT workflows, for example through the introduction of targeted notification channels when a need arises? Our quantitative methods were perfectly suited for this kind of analysis. Paper reviewers must have thought so too: it was awarded Honorable Mention at CSCW 2017.

Private Peer Feedback as Engagement Driver in Humanitarian Mapping (PDF). Here we looked at the impact of private validator feedback on the tasking manager on newcomer retention. This is a classic behavioural study based on loads of prior work, but with HOT as a novel setting – it’s a bit unusual because on the tasking manager, the peer feedback relationship with validators is more akin to private mentoring than the public rating you often find it on other platforms. Maybe as a result, we found that critical/corrective feedback in HOT did not actually appear to discourage people, in contrast to what you can commonly find on platforms with public reviews. One the other hand, feedback that included social affirmation and appreciation was significantly associated with increased newcomer retention. Maybe this is due to the online nature of the practice, the fact that HOT remote participation can happen in a kind of “depersonalised” space for many? In the absence of other prominent social cues, small phrases of support can likely have a powerful effect. However, note that like the other papers this is an observational study rather than a controlled experiment, so I would love if if people tried to reproduce the findings with other methods. In any case, this paper is another favourite of mine – and it was awarded Honorable Mention at CSCW 2018.

A very rough summary

So, coming back to the opening questions – are the most highly engaged contributors “born or made”? As you may expect, the answer is “yes” :)

To paraphrase the conclusion section of the dissertation, sustained community engagement is only partially a matter of optimising the contribution process. Overall it appears that a pursuit of indiscriminate community growth would likely be an inefficient use of organiser resources, in part because it seems unlikely that prolific mappers can be “created” by a particular process, and instead many will drop out early. Instead, other factors beyond the contribution process are likely just as important. This includes factors relating to the individual person, such as their interests and prior experience, and factors relating to their participation context, such as the presence of a supportive community that organises regular activities. However, the evidence also suggests that newcomers who are likely to become highly engaged can be discovered, for example through public events like mapathons and the promotion of major mapping actions, and these newcomers may then need some support in order to get started.

Advice to prospective PhD students

Early on during the PhD, my amazing supervisor Licia Capra recommended to structure the research as individual papers rather than a large monograph, and to try to publish each project as we go. This was a transformative decision that significantly improved my PhD experience! It gave me regular deadlines, I learned a lot from reviewer feedback, and it meant that the main work was already written up by the time I needed to produce the final dissertation. It meant I was able to finish the first full dissertation draft in only 8 days, plus a couple of weeks of refinements; and it meant that I was not stressed about my viva (the final verbal examination for PhD students in the U.K.), because the work had already been reviewed by experts, sometimes multiple times (I had to resubmit two of the papers after they were initially rejected for publication.) Over time this gave me a good sense of the strengths and limitations of the work, and I learned some key methods from the peer feedback that I relied on in the later work.

Granted, a paper-based approach may not be suitable for everyone; our particular research approach lent itself to project-based work. But even if you decide against this approach, I would recommend not to leave the writing until the very end. It is quite well-established that PhD life is a mental health hazard. In my personal experience, and from talking to others, this is in part because you will find yourself in a perpetually drifting state where it’s at times hard to tell if you’re doing well, and it is hard to retain a sense of certainty that you’re on track. Instead your work resembles a seemingly infinite and never-shrinking list of tasks with indeterminate outcome. So in addition to maintaining an active life outside the PhD, I would also recommend to structure your work in ways that help you manage these uncertainties. Anything that makes your work and your progress more tangible will help you in the long run.

And then…

Anything that comes after such a glorious journey with HOT and Missing Maps would have a lot to live up to, so I feel blessed that since 2017 I’ve been a postdoc at the Oxford Internet Institute, and I couldn’t have asked for a better place to land. I’m not sure yet if I’ll stay an academic for life, but for now it’s perfect. You can follow my work on Twitter.


Weekly Updates

I continue to make progress with the Missing Maps projects. I think for the moment, since I’m doing the same things over and over - buildings and trees - that I’ll keep the diary entries to a weekly thing, or perhaps only when I learn/try a new process; for example, drawing roads.

Development Seed announced the launch of mapping.team, a tool to coordinate mapping and build communities. 1 | © kamicut, Development Seed

About us

  • In our last issue we reported on the vacancies on the OSMF Board of Directors. A late update is that four posts will be available for election, not three as we reported. Heather Leson is retiring from the board before the end of her term.

Mapping

  • OpenStreetMap Guinea announces in a tweet the collection of data on illegal dumping points in the Commune of Ratoma in Conakry, which are visualised on a thematic uMap map.
  • Ruben suggests extending opening_hours by an additional value for amenities which require an appointment.
  • Jeremiah Rose suggests footway=indoor for marking indoor routes within a building mapped with Simple Indoor Tagging but has not so far provided the distinction to the existing highway=corridor.
  • Andrew, from Apple’s Maps team, has uploaded potential road and routing related issues in Angola, Egypt, Kenya, Rwanda, South Africa, Tunisia and Uganda to MapRoulette.
  • SK53 tried to unify the tagging for showgrounds and posted the various inconsistent approaches he found in the UK.
  • A German-specific discussion concerns a dispute as to how many lanes a road has if there are no markings. A article in the Zeit Online provides (de) (automatic translation) arguments for mappers who think the number of lanes is determined by the physical width.
  • Lyft, an on-demand transportation company based in San Francisco, USA, reports about its efforts to detect, fix and report map errors in OSM.
  • Miami University students and geographic information systems (GIS) professionals have started a “Bahamas Mapathon” to help the Bahamas after the devastating Hurricane Dorian.

Community

  • Ireland’s OSM community has submitted an application to become a local OSMF chapter for mappers in both parts of the Irish Island, the Republic of Ireland and Northern Ireland. All, except one, welcome the idea of a local chapter for mappers in the two countries.

Imports

  • Brian M. Sperlongano would like to import the boundaries of the Census-designated places (CDP) in Hawaii. However, there are uncertainties about tagging, as CDPs do not meet the criteria for boundary=administrative.
  • At SotM US 2019, Facebook demonstrated their computer vision software to detect buildings suitable for import into OSM with RapiD.

OpenStreetMap Foundation

  • Nuno Caldeira has noticed a new button on Facebook maps that can be used to report map errors. Unfortunately the error report process does not credit OSM, instead referring to “Facebook maps”. Nuno had already reported the incorrect identification to Facebook a year ago and three months ago asked the OSM Foundation to persuade Facebook to attribute it correctly.
  • OSMF’s trademark policy is still a current topic on the mailing list and not everyone agrees with the current procedures.
  • With the Annual General Meeting of the OpenStreetMap Foundation impending, Michael Reichert provides a reminder (automatic translation) about how to renew one’s membership, with some hints to make life easier for the Membership Working Group. He also calls on others to join the Foundation.

Events

  • This year’s State of the Map conference was sold out on 6 September 2019. If you missed out you’ll be able to livestream or watch the recordings, see the programme for details.
  • The Einfachbahn (de) (automatic translation) initiative organised (de) (automatic translation) a mapping party (de) in Frankfurt am Main on 12 September. Two groups practised the acquisition of railway-related geodata in Frankfurt-Höchst and Frankfurt-Rödelheim stations and subsequently edited with JOSM. In addition to mapping, there was a lively exchange of information on railway geodata.
  • FOSS4G SotM Oceania is looking for a host for next year’s event.
  • The next French-German cross-border OSM community meetup will take place (automatic translation) on 28 September 2019 in Strasbourg.
  • The SigInfoLibre blog talks about (automatic translation) the sub-regional workshop for leaders of OpenStreetMap communities in French-speaking Africa. The workshop is being held at the University of Lomé in Togo with the support of the Organisation Internationale de la Francophonie. On the menu: participants talk about OpenStreetMap Governance, project engineering, communication techniques, and free digital mapping techniques.
  • You often hear of the University Rapperswill, Switzerland, in the context of innovative OSM technologies and applications. So it makes perfect sense that Rapperswill has applied to host the next State of the Map conference from 19 to 21 June 2020.
  • The FOSSGIS 2020 (automatic translation) conference, the annual meeting for open source geo-software and OpenStreetMap in Germany, will take place from 11 to 14 March in Freiburg. As usual, the last day is always a Saturday and dedicated to OSM.
  • Missing Maps is organising another mapathon at the Médecins Sans Frontières offices in Brussels. The Save the World – Map it titled event will take place on 24 September 2019.
  • Ilya Zverev reports from SotM-US – Wednesday (automatic translation) – Thursday (automatic translation) – Friday (automatic translation). (ru)

Education

  • CartONG, a French NGO specialising in mapping and related services for humanitarian and development organisations, is offering a position for a data specialist based in Chambéry (France).

switch2OSM

  • Severin Kann reported, via Twitter, that in Krakow OpenStreetMap is used on trams for real-time position display.

Software

  • [1] Development Seed announced the launch of mapping.team, a tool to coordinate mapping and build communities. The diary entry provides a fairly comprehensive overview and recommends that you test the beta version, create an own instance, or contribute code to the GitHub hosted project.
  • Simon Poole has published a feature preview of the upcoming versions of the Vespucci editor for Android devices. The first beta of Vespucci 14 is expected to be released in September.

Releases

  • OsmAnd announced the release of version 3.0 of their iOS app. The new version adds a quick action feature to access various map actions from the home screen, the ability to download a missing region map directly from the context menu, and added hints for tags and values to the advanced OpenStreetMap editing screen.

Did you know …

  • … the OSM-Science mailing list? A place to discuss research ideas, to develop surveys, and to communicate with science-oriented OpenStreetMap community members.
  • … there are at least two kinds of gas-driven vehicles? Some run with liquefied petroleum gas (fuel:lpg), some use compressed natural gas (fuel:cng). Don’t get them mixed up when tagging fuel service stations, as the two are incompatible with each other!

OSM in the media

  • LinuxInsider reports on the new OSGeoLive release. OSGeoLive is a Linux distribution that specialises in geospatial applications.

Other “geo” things

  • OpenMaptiler blogs on the highlights from FOSS4G 2019 in Bucharest.
  • Elijah Zarlin from Mapbox presents 15 projects that have been created recently with Mapbox tools.
  • The Pudding have produced a People Map of the US, where city names are replaced by their most Wikipedia’ed resident. There is also a UK for those who prefer to see the other side of the Atlantic.
  • Google Maps now also includes ridesharing offers “for the first and last mile” in its public transport routing in order to save even more footsteps.
  • The North American Datum of 1983 is the Everest of the classical survey art, completed just before the satellite geodesy revolution swept all aside. Tim Burch discusses the four plate-fixed terrestrial reference frames that will replace the venerable NAD83 in 2022. A combination of correcting the 2m offset in NAD83 from the geocentre and dropping the US survey foot and adopting the international foot, will see some points apparently move by up to 4m.
  • It’s nothing new that Pokémon GO players like to cause controversy in the OSM community. The Silph Road shows that some OSM tags prevent Pokémon from spawning in certain areas of the game. Of course, this is not due to OSM itself, but to the processing of the data by Niantic.

Diversity and Inclusion in OSM

We’re hosting an open discussion about “Diversity and Inclusion” in OSM at State of the Map.

“How can OSM be more diverse and inclusive? What can we do to improve this across all the various OSM spaces, including OSM governance? Diversity is the range of human differences, including but not limited to race, ethnicity, gender, gender identity, sexual orientation, age, social class, physic

We’re hosting an open discussion about “Diversity and Inclusion” in OSM at State of the Map.

“How can OSM be more diverse and inclusive? What can we do to improve this across all the various OSM spaces, including OSM governance? Diversity is the range of human differences, including but not limited to race, ethnicity, gender, gender identity, sexual orientation, age, social class, physical ability or attributes, religious or ethical values system, national origin, and political beliefs. Join us to share your lessons and ideas on how we might grow and support a Diversity and Inclusive approach in OSM. There are Diversity and Inclusion groups across other ‘open’ communities. OSM has a diversity talk mailing list. This will be the place where the community can continue to connect after SOTM.” full session details

The goal of the session is to give space for the OSM community to talk about their needs and to plan a way forward to supporting OSM on this journey. We will do this with small group discussions to support shared dialogue.

Details: Sunday, September 22, 2019 1400 - 1500 CEST Kleiner Hörsaal

You can learn more about our planning here

This session is being co-hosted by the Diversity mailing list colleagues.

See you there!

Ein kleines Plädoyer für die stop_area_group.

Ich habe mich in den vergangenen Jahren viel mit den Rohdaten von Openstreetmap beschäftigt und seit einiger Zeit mappe ich auch viel (meistens rund um das Thema PTv2). Dabei habe ich ein paar interessante Entdeckungen mit dem PTv2-Schema gemacht. Meines Wissens ist ja die stop_area_group nicht in dem Schema integriert und ich habe (wie ich finde) ein paar gute Gründe für die Aufnahme in das PTv2-Schema gefunden. Große Bahnhöfe in Hauptstädten sind ein gutes Beispiel dafür. Viele Bushaltestellen, unterschiedliche Anbieter, Nahverkehr, Fernverkehr, Metro, S-Bahn, und, und, und … Als ich mir den Kopenhagener Hauptbahnhof mal genauer unter die Lupe genommen habe (nachdem ich das S-Bahn-Netz aktualisiert hatte), sind mir Ideen gekommen wie man das Ganze etwas strukturieren könnte. Jede Verkehrsart (Bus, S-Bahn, Zug) bekommt eine eigene stop_area, die zusätzlich mit den jeweils bekannten Elementen bus=yes/light_rail=yes/train=yes versehen wird. Nun können unterschiedliche network-Tags zum Einsatz kommen. Es fahren ja zum Beispiel Busse für einen Verkehrsverbund, andere wiederum in einem Fernbusnetz. Auch Abweichungen im name-Tag könnten hier berücksichtigt werden. In Kopenhagen heißt das: Movia (Busse im Takst Sjælland) schreibt die Haltestelle oft Hovedbanegården (mit der Straße, an der die Haltestelle liegt) DSB (S-Bahn; Zug) schreibt die Haltestelle København Hovedbanegård (meist abgekürzt København H) Elemente, die zu mehreren stop_areas passen würden, finden Platz in einer eigenen stop_area, welche mit dem neuen Tag type=infrastructure versehen werden könnte. Alle diese stop_areas wären dann Mitglied in einer stop_area_group.

Und was ist jetzt der Vorteil? Linien eines Verbundes werden oft in einer master_route zusammengefasst, die dann Platz in einem network=Verkehsverbund_xy findet. Eigentlich müssten die Haltestellen an sich die gleiche Priorität wie die Linien mit den entsprechenden Haltestellen (stop; platform) bekommen. Beim Auswerten der Rohdaten der Linien fallen zum Beispiel die Punkte public_transport=station erst mal unter den Tisch. Wenn Haltestellen an sich ebenfalls in einer network-Relation zusätzlich zusammengefasst werden würden, hätte man eine zweite, einfache Möglichkeit der Datenauswertung. stop_areas mit gleichem network-Tag könnten dem Verkehrsverbund XY zugeordnet werden. Man könnte aber auch die stop_area_group an sich auswerten, das man einen Überblick der gesamten Station erhält. Und wenn es nur eine stop_area gibt? Dann bleibt einfach alles beim Alten. Diese Überlegungen sollen keine „Verschlimmbesserung“ des bestehenden PTv2Schemas sein, sondern eine sinnvolle Ergänzung. Ich habe dazu eine kleine Grafik erstellt die unter folgender Adresse angesehen oder heruntergeladen werden kann. Diese Grafik (stop_area_group.svg) ist CC0 (Public Domain) und kann sehr gerne weiterverwendet werden.

Getting to Grips with Missing Maps

I’ve just found that by initiating projects through the Missing Maps website, your time spent on projects can be timed automatically with a sort of stopwatch feature. This will help me keep track of my contributions to the projects as time goes by. As such I will be cross-referencing this diary and my Missing Maps account, which uses HOT Tasking Manager as the adjudicator.

Solar panels in the UK - 100,000 spotted!

The OpenStreetMap UK community has come together for a 3-month “quarterly project” to find all the solar panels in the UK. And the results so far… wow!

-> We’ve just reached over 100,000 standalone solar PV installations mapped in the UK!

-> Plus we also have almost 600 solar farms mapped, representing almost 5 gigawatts!

The OpenStreetMap UK community has come together for a 3-month “quarterly project” to find all the solar panels in the UK. And the results so far… wow!

-> We’ve just reached over 100,000 standalone solar PV installations mapped in the UK!

-> Plus we also have almost 600 solar farms mapped, representing almost 5 gigawatts!

To give you an idea of completeness: the UK government believes there are about 1 million solar panels in the UK, and official solar farm listings have about 8 GW. What we’ve mapped so far is way more than I thought we’d manage, so I really deeply want to thank every person who contributed, large or small. We can use these data to pilot CO2-saving initatives - and so can anyone else. Open data for the win!

Here are a couple of simple plots from me, to show where the items are in the UK. (The data I’ve used are from yesterday, which is why my plot says not-quite-100,000 items.) I’ve plotted two different types of item: (1) “standalone” solar panels (i.e. ones that are not inside solar farms); (2) solar farms. You’ll notice the distributions are really different:

(The images aren’t showing up…. you’ll have to view them on my blog where I originally posted this)

Some of the darkest blobs on the map are evidence of focussed effort. I know that Jerry (SK53) has been mapping around Nottingham, Cornwall and other areas, so may be the source of some of these blobs. We’ve shown that with some local effort, and a bit of scanning through imagery, a lot of this can be done.

You’ll notice that many of the solar farms are in the southern part of the UK, at least according to our data. That’s not unexpected!

For more detailed data breakdowns, you can peruse Gregory Williams’ solar mapping analysis site.

We have more time to go until the end of the quarter… and we’ll be able to use the data for sustainable energy projects whenever you contribute - so please do join in!


Missing Maps

I’ve started working on projects for Missing Maps, a volunteering collaboration that puts vulnerable people across the world on the map, with a view to being able to locate them and provide aid to them in the event of a catastrophe or natural disaster. Today I spent 1 hour adding some buildings and nearby habitation in an area of Tajikistan.

Desafios das Geocomunicações

A produção de cartografias e a análise dos mapas online são portanto dois lados de uma questão contemporânea a ser respondida de modo interdisciplinar e dialógico, ensinando a todos a ler, escrever e interpretar mapas conforme a realidade local, por mediação de uma prática pedagógica crítica, conforme a teoria de Paulo Freire.

A produção de cartografias e a análise dos mapas online são portanto dois lados de uma questão contemporânea a ser respondida de modo interdisciplinar e dialógico, ensinando a todos a ler, escrever e interpretar mapas conforme a realidade local, por mediação de uma prática pedagógica crítica, conforme a teoria de Paulo Freire.

Geografia, Computação e Comunicação utilizam das informações geoespaciais (os nossos rastros de GPS e as bases de mapas online) e o tema tem se tornado a fonte para ideias inovadoras na cidade e no campo.

A educação para Geocomunicações tem demandado a profissionalização de analistas e técnicos e para isso o Instituto Brasileiro de Pesquisa e Análise de Dados fornece um curso online (MOOC) para quem deseja aprender como “dominar o GPS” e fazer os próprios mapas, sejam eles públicos ou privados, para fins pessoais ou coletivos.

Paradigma das Geocomunicações: o poder do habitante

No entanto, somente o habitante, e não o visitante, é quem pode reconhecer o cotidiano de um território, oferecendo informações para um mapa global sobre a qualidade dos seus dados. Nenhum autômato é capaz de conhecer o território usado pelas diversas redes humanas e suas dinâmicas com a natureza.

No entanto, somente o habitante, e não o visitante, é quem pode reconhecer o cotidiano de um território, oferecendo informações para um mapa global sobre a qualidade dos seus dados. Nenhum autômato é capaz de conhecer o território usado pelas diversas redes humanas e suas dinâmicas com a natureza.

Estudos com comunidades ribeirinhas, amazônicas e de favelas comprovam que existem distinções entre a informação geográfica produzida por voluntários (VGI) e a informação geográfica proprietária (PGI). Esta distinção crítica tem como ponto de partida o método comparativo.

Dicotomias dos mapas online Por isso mapeamentos horizontalizadores tendem a ter sido processados por metodologias empoderadoras, que dão voz e ouvem os habitantes, porém servem, na maioria das vezes, para estrangeiros, em outras palavras aqueles que desconhecem o território e que são, na maioria dos casos, os que demandam dos mapas no cotidiano para mobilidade.

Por sua vez a verticalização tende a processar metodologias desorganizadoras, que dão prioridade para lugares econômicos e políticos em relação aos lugares culturais e sociais. A exemplo dos becos, vielas, feiras livres, camelôs, trilhas, hidrovias, ocupações, etc.

Causas de contrastes cartográficos

O que Milton Santos conceitualmente denominou como “circuitos inferiores” e “circuitos superiores”, na Geografia Crítica, se reproduziu na análise da comunicabilidade dos mapas online comparados nos territórios de Cachoeira-BA, Xapuri-AC, Complexo do Alemão, Rio de Janeiro-RJ.

Nestes três casos a representação dos circuitos superiores locais supera as dos inferiores para os mapas do Google Maps e o inverso ocorreu nos mapas do OpenStreetMap. Isso atesta que as VGI são horizontalizadoras porque são processadas por uma ação cartográfica - construída com base no olhar do habitante - e as PGI são aqui atestadamente verticalizadoras, porque são processadas por funcionários em um atividade cartográfica.

Esse debate está aberto às novas metodologias de pesquisas de dados mas sobretudo desafia a sociedade brasileira a pensar de modo autônomo, crítico, organizado e localizado sobre a “corrida infoespacial” que estas plataformas de mapas virtuais vivem e qual delas oferece mais vantagens competitivas para cada território na época que vivemos, a chamada Quarta Revolução Industrial.

A distinção entre as correntes científicas que usam o termo Geocomunicação e o termo Geocomunicações se faz essencialmente pelo método. Enquanto o primeira corrente se propõe a pensar os usos e regulações de apenas uma plataforma de mapas virtuais, a segunda corrente compara os usos e regulações em duas plataformas e pressupõe que existem nestas técnicas de cartografia digital uma dupla tendência, a horizontalização e a verticalização das representações socioespaciais através do GIS.

O método que produz o fundamento do campo das Geocomunicações alicerça um pensamento latino-americano sobre a globalização dos mapas virtuais por empresas, governos e cidadãos de modo diferente e integrado pelos territórios do planeta.

Metodologia de comparação de mapas online

Esta metodologia tem três passos que buscam aferir de modo quali-quanti sobre os “contrastes cartográficos” na representação de um território.

Basicamente comparam-se dois mapas de um mesmo território em uma mesma escala de zoom digital escolhida conforme a demanda da pesquisa.

Coleta das colaborações

O primeiro passo recorre à coleta das colaborações, ou seja, a escolha de um determinado recorte para a pesquisa (local ou regional) com objetivo de comparar as representações em duas ou mais telhas (ou frames) em escalas cartográficas fixas. Nesta pesquisa utilizamos da plataforma alemã Geofabrik e a ferramenta de pesquisa online Map Compare (Comparador de Mapas). Após o print-screen da comparação começam as análises dos frames.

Análise das visibilidades

O segundo passo é a análise quanti das formas estruturadas que são visíveis no mapa classificando os dados entre “símbolos” ou “nomes”, ou seja, não considerando aspectos como cores, apenas os elementos que comuniquem, conforme Juan Díaz Bordenave, os objetos utilizados ou desutilizados de um território em estudo comparado.

Análise das territorialidades

O terceiro passo é a análise quali das funções processadas (conforme a imagem) que são enunciadas por estas formas estruturadas quantificadas anteriormente. Podemos com isso classificar os lugares, vias ou áreas (quantificados a partir de nomes e símbolos) como “políticos”, “econômicos”, “sociais” e “culturais”, não considerando as intersecções possíveis - como sociocultural ou sociopolítico - considerando portanto a função que prevalece no cotidiano conforme o ponto de vista do pesquisador, constituído pelo senso do “nível espacial”, conforme definiu Merleau-Ponty, entre a presença e a pertença ao território (ou loco) da pesquisa ou ação.

Horizontalização e verticalização Este método dialético de estudo da representação geoespacial de uma sociedade considera três fatores-chave:

1) se o território está mapeado de modo que horizontaliza ou modo que verticaliza as informações para todos que podem acessar o mapa online de um mesmo território,

2) se o mapeamento foi uma ação ou uma atividade, partindo de voluntários ou funcionários

3) se todos os lugares, vias e áreas usados no cotidiano estão representados neste recorte partindo do senso do habitante, quem melhor conhece as dinâmicas locais.

Exemplo: https://upload.wikimedia.org/wikipedia/commons/1/19/Resina_contraste_acesso_18_de_novembro_de_2018.jpg

Com o propósito de desenvolver uma metodologia de análise para orientar aqueles que ambicionam “analisar, refletir e agir na relação entre a cidade, os mapeadores e os mapas online”, o autor empreende uma análise comparativa entre as plataformas Google Maps e OpenStreetMap – orientado pela preocupação com a comunicabilidade dos mapas – e leva a efeito um estudo sobre os mapeamentos online do centro urbano mais moderno do município de Cachoeira, no estado da Bahia, com o projeto de Extensão MapaRec, mas podemos falar de diversos outros casos de ação cooperativa, como o povoado de quilombolas do Povoado Resina, no município de Brejo Grande, no estado de Sergipe.

Ontologia e epistemologia para estudos em OpenStreetMap

O termo Geocomunicações (originado do termo Geocommunication em inglês ou Geokommunication em dinamarquês) foi apropriado (em português) pelo comunicólogo Antônio Laranjeira, na dissertação intitulada A comunicação dos mapas (2019) na qual o autor trata de uma investigação sobre aspectos filosóficos, sociológicos, geográficos e comunicacionais das plataformas Google Maps e OpenStreetMap.

O termo Geocomunicações (originado do termo Geocommunication em inglês ou Geokommunication em dinamarquês) foi apropriado (em português) pelo comunicólogo Antônio Laranjeira, na dissertação intitulada A comunicação dos mapas (2019) na qual o autor trata de uma investigação sobre aspectos filosóficos, sociológicos, geográficos e comunicacionais das plataformas Google Maps e OpenStreetMap. Esta investigação é atualmente a única do Brasil na lista internacional de pesquisas sobre o tema.

O termo Geo-communication, citado pela primeira vez em inglês pelo geógrafo e comunicólogo Lars Brodesen, em sua tese intitulada Geo-communication and Information Design (2008) que serviu como premissa para uma definição deste subcampo científico nutrido pelos usos e regulações de diferentes modelos de sistemas de informações geográficas oferecidos via o ambiente de convergência entre a web e o GIS - em outras palavras, a geoweb.

Conceitos para análise da comunicabilidade dos mapas online Fundamentado em teorias da Espacialidade e da Cibercultura, a dissertação apresenta uma leitura original sobre três conceitos que orientam a metodologia comparativa do estudo sobre os mapeamentos colaborativos. São eles: 1) colaborações de André Lemos (colaboração em rede e colaboração em massa), 2) territorialidades de Rogério Haesbaert (territorialidade espacial e territorialidade informacional) e 3) visibilidades de Paulo César Gomes (possibilidades de múltiplos mapas em múltiplas escalas de zoom digital).

Esta pesquisa que “delimitou” pela primeira vez campo das Geocomunicações está fundamentada na teoria da produção do espaço (Henri Lefebvre), no método de análise espacial dialético (Milton Santos) e na metodologia experimental de comparação de mapas online (Antônio Laranjeira).
