This is a personal note so I remember the settings to use depending on my method of transportation:

Bicycle:

• Mode: 360 Timelapse Video
• Interval: 0.5 seconds
• Resolution: 5.6k
• Remember to point one camera to the right, the other to the left. Maximizes aerodynamics and captures better quality images of signs.

Walking:

• Mode: 360 Time Lapse Photo
• Interval: 2 seconds
• If photos appear too clustered, increase time of interval

Car:

• Mode: Standard Video
• Resolution 1080p or 4k
• Frame rate 30 fps for forward view
• Frame rate 60 fps for side view (to reduce motion blur)
• Field of view: Linear for side shots, Wide for more vertical coverage. Never use SuperView
• Horizon Leveling: Off
• Stabilization: Off or Standard. Can warp the images
• For side shots, best to angle 45 degrees for best of both worlds.

• Raquel Dezidério Souto wrote, in her OSM User Diary, about the second meeting of the 2026 OpenStreetMap Workshop Series. The meeting took place on Friday 22 May and covered the generation of aerial imagery from drone photos on OpenDroneMap; uploading images to OpenAerialMap; mapping with custom images in OSM editors; and creating relationships, with an emphasis on multipolygons. The event provided certificates to those who completed the tasks, and registration remains open for the remaining sessions.
• Simon Ertel has launched Drevesa, an interactive map that transforms Ljubljana’s ‘Trees of the Year’ into a gamified urban trail. The project invites people to find and visit each winning specimen elected by citizens since 2019. By visiting these remarkable trees in real life, users can unlock information about tree species and learn the basics of arboriculture.
• Franjo Lukežić shared the first in a set of heuristics that they use while field surveying, with the first one regarding how to survey highways.
• Is editing config files very scary for you? If not, Mateusz Konieczny encourages you to help with the iD tagging schema.
• Bastian Greshake Tzovaras reflected on the technical and socio-technical challenges of giving a workshop about OSM and open source map tools.

Local chapter news

• Katja Haferkorn reported ► that FOSSGIS e.V. participated in the 74th German Cartography Congress 2026, with an exhibition booth and a keynote presentation.

Events

• Tickets for the SotM (28 to 30 August 2026) in Paris are now available.Information on accommodation options around the venue can be found on a uMap (by Magnus Sälgö). In the SotM telegram channel, Sheldon also suggested finding possible accommodation options via bewelcome.org and couchers.org.

OSM research

• Héctor Ochoa-Ortiz and others have concluded that the current micro-tasking model employed by the HOT Tasking Manager hampers the development of spatial collective intelligence, producing fragmented and inconsistent outputs that ultimately diminish overall data quality. In their study, the researchers proposed several practical measures to mitigate these issues, including the use of overlapping task boundaries and mechanisms to encourage implicit coordination among contributors.

Maps

• The Civic Control platform has published a map of cultural heritage sites in Dnipro (Ukraine). This resource contains information on architectural monuments and newly identified cultural heritage objects, including addresses, protection status, registration documents, ownership information, and photographs. The project aims to improve transparency in the field of cultural heritage protection and facilitate public access to relevant data.
• HuggeK has developed golftiles, an open-source project to generate golf-centric PMTiles for mapping applications that want to highlight golf course maps.

Open Data

• Foursquare has open-sourced the Foursquare OS Places dataset, a global database of more than 100 million points-of-interest data, under the Apache License Version 2.0. They have invited public participation through its Placemaker Tools platform, which allows users to contribute to and improve the OS Places dataset.

Software

• Ian Wagner wrote, on Stadia Maps’ blog, about how Valhalla and OpenStreetMap are used to build routing profiles that encode each vehicle’s physical and legal constraints from the ground up.
• Tina and Eugene explained how OsmAnd turns 3D building tags from OpenStreetMap data into rendered buildings displayed within the application.
• didier2020 has written a new analyser for Osmose, which detects potentially duplicated POIs on OpenStreetMap. The source is available on GitHub.

Hi folks! I’m up for election to HOT’s voting membership this year (thank you, Pete!). As a part of that process, I’m posting my answers to their prompting questions here on my OSM diary.

I know that I already owe this community a summary of my previous research within the OpenStreetMap ecosystem – and what’s changed since then. By way of explanation and apology: I wanted to flag that I will be giving a talk at this year’s State of the Map in Paris with an update on my previous work. You can see the talk I gave in 2022 here. I also gave a talk at the HOT Summit in 2021.

I also want to flag that no LLMs were used in the writing of these answers: while I do use them sometimes for more functional, repetitive, or iterative work, I did not use them below. Writing is often a form of thinking for me, and for these answers, I wanted to prioritize that process.

What does HOT mean to you?

In the last 6 or so years, HOT has both professionally and personally changed how I think about technology, community, and crises. It’s also meant different things at different times for me – which I wrote a bit more about in the question below.

In short: I’ve come to see HOT (and humanitarian mapping more broadly) as a kind of canary in the coal mine for the broader technology ecosystem at large. The questions I found here, at HOT and across OSM are ones that I have later found in the broader ecosystems they feed into (and even the world at large): questions about navigating permacrises, about AI, about shifts in funding landscapes, about ethical dilemmas for data pipelines, about cross-cultural community-building, and many, many others.

How did you become involved with HOT?

I have perhaps an unusual path to being involved with HOT: I was an anthropologist and ethnographer of the ecosystem of humanitarian mapping that HOT feeds into before becoming involved as a mapper and facilitator in the past few years.

During my MA from 2019-2022, HOT and the humanitarian mapping ecosystem was the research ‘field site’ for my MA, meaning a place I ‘went to’ in order to ‘do research’, something that anthropologists call “participant observation”. As a part of that process, I spoke to a number of mappers within HOT and in the broader mapping ecosystem, tried my best not to be extractive during the research process, and shared my own knowledge openly in return. Pretty much everyone I spoke to was kind and open to speaking with me, which I really appreciated. The whole process was incredibly formative, even as I shared critical research about the nature of humanitarianism, or even about HOT itself and the broader ecosystem of work and economic processes that it might point towards, according to the literature.

This experience led directly to me wanting to contribute to the same processes I had observed and tried to understand as a researcher, so I went from studying digital communities to managing and stewarding them.

Since 2022, I’ve become a kind of ‘open ecosystem practitioner’, working as a facilitator and most recently as a kind of ‘mapping artist’ at a variety of organisations: with the Alan Turing Institute, Internet Society, British Red Cross, and Open Knowledge Foundation to name a few. This took me to worlds outside of humanitarian response, but enabled me to return to facilitate a call on AI-assisted mapping with HOT’s Community Working Group back in 2023, and inadvertently made me see HOT in a different light as well.

Working in parallel spaces to humanitarian technology for the past few years has made me reflect with more nuance about the role that HOT plays not only within humanitarian response, but in the broader political landscape it is a part of (and lies in parallel to).

Can you share your involvement in HOT, mapping, and/or humanitarian response?

A few years later, I now organise mapathons for the Missing Maps project on behalf of the British Red Cross as a professional facilitator. I sometimes consult with various members of the mapping research and tech ecosystem, join in-person and remote mapathons with the London Missing Maps and Geomob folks, and make art (usually related to maps). I’ve also (very) slowly started to map my neighborhood and hikes, which has been a totally different entry point to mapping entirely. I still wouldn’t call myself an expert mapper to this day - though I’m perhaps more of an expert in ‘communities’ more than anything else, and a translator between different parts of the ‘mapping supply chain’.

Why do you want to become a voting member?

I see this as an opportunity to re-engage with the HOT community in a more formalized way, and to share many of the skills and experiences I’ve learned over the past years in similar and aligned spaces. This gives me both a structure and a format to do so, especially as someone that now finds myself stretched across a few different projects.

As a voting member, what do you see as your most important responsibility?

What I see as perhaps my most important responsibility is the same reason why I’d like to become a voting member: to be a contributor and supporter of a project that I’ve learned a lot from, and to represent a perspective that might not be currently represented within the voting membership, particularly one informed by critical-scholarship.

What do you see as HOT’s greatest challenge, and how would you help address it?

I think we’re in a very challenging time for the type of work that HOT does on a few levels. On one hand, I remember that my research revealed questions and vulnerabilities within the mapping supply chain itself (things like satellite imagery issues, for example!), or the rise of AI-assisted mapping and its implications for data quality (amidst other data quality questions with beginner mappers). These problems are still endemic, though they have evolved.

Secondly, as an ecosystem actor, I can see the wider issues of funding and sustainability that are absolutely gutting the humanitarian and non-profit space, and I’m keen to support sustainable and ethical work during this challenging period.

To address these issues, I obviously think deep, strategic work is important, as well as connecting to allies and other aligned folks facing similar issues. Perhaps we might look to other ecosystems outside of humanitarian response - and to others with an aligned ethos.

Overpassによる事前調査

bicycle=yesやdesignatedなhighway=footwayやpathはほぼなくなっていた overpass turbo

  • 点地物
  • bicycle=yes:no:dismountで表現可能
  • =bollard、gateなどもある
• oneway:bicycle=no
  • 自転車のみ一通逆走可能
• cycleway:left:segregated=yes
  • ポール付きレーンとか？
• Proposal:Separation - OpenStreetMap Wiki
  • なにで・どのように区切られているかの表現
  • cycleway=trackは通行空間自体の表現としてまた別っぽい
  • cycleway:left:separation:right=flex_post　とかか、一本のwayの左側のcyclewayの右側の分離
  • cycleway:right:separation:left=curb　指定部分の植木で分ける場合
  • 現状多分cyclosmにもサイクリングマップにも描画されない
  • cyclewayのkeyのつかないsegregatedな指定部分の表現にはやや合わない気がする
• cycleway=lane
  • 自転車通行帯
  • 中央分離帯などで車道が二本の表現になっている場合はcycleway:left=laneか
  • wikiには「日本の通行帯はadvisory」の記述があるが、路駐や右左折時であっても侵入を禁止している国や地域がそもそもまれなため、すべてのウェイにタグ付けする以外の方法を考えたほうがいいのではないか（法律の文言通りにタグ付けする必要はないと思う）
• bicycle=use_sidepath, highway=cycleway+oneway=yes
  • 自転車道
• highway=cycleway
  • 自転車道
  • highwayと一体化させる場合はcycleway=track
    • ただし日本における自転車道の定義が物理的区画を要求しているため、原則として異なるウェイで描写するべきだろう
• segragated=yes
  • 普通自転車通行指定部分
• cycleway=shared_lane
  • ナビマーク
• cycleway=trackについて
  • OSM上では区切られていることが条件
  • highway=cyclewayと一緒に使うのは意味がない
  • 日本の凡例ではhighwayと同一のwayで表現するときの自転車道　JA:Tag:highway=cycleway - OpenStreetMap Wiki
  • ただし、自転車専用通行帯や普通自転車通行指定部分にも分離されているものがあり、問題となりうる
• segregated=yes

  • 押し歩き
• ソースにこれを入れる
  • 出典：「交通規制情報」（公益財団法人日本道路交通情報センター https://www.jartic.or.jp/ x年‎x月‎xx日利用）　データは独自に編集しました

感想

• 編集履歴が数件しかない人の記入はほぼどこかしら間違っている
  • というか体感7~8割が間違っている
• designatedはいらない
  • ~の用に供するとか、法律上xx向けに作られているものとか？
  • このほかにも見た目による厳密な区別の可否、意味的な厳密さ、法律上の位置づけなどを一つのkey=valueに中途半端に盛り込んだ表現は、単に冗長・不十分か、地域ローカルでしか通用しないと思う
  • 簡便や描画のために有用であり、”ざっくりとした”表現に対する実態と含意が一致する場合に限り有用、この点で今の日本の自転車インフラとタグ付けの対応は割と機能していると思う
• cycleway=trackもウェイ自体の表現ではなくあいまい
  • 後述の描画関連の要望で解決すべきと思う
• 坂や階段のスロープにcyclewayとかdesignatedをつけるミスが多い
• 正しくマップしようとした結果と、レンダリングの派手さが一致しない
  • ”間違った”マッピングがされたものは、できれば派手に表示されてほしい秀逸なインフラが含まれる
    • =track、=designatedとか
    • よくわからない・品質が一定でない規制やインフラが蔓延しているのは国土交通省や自治体や警察の責任でもある
• サイクリングロードのタグ付けはhighway=何にすべきか　緊急用河川敷道路（河川管理用道路）
• 描画関係の希望
  • 進入禁止箇所・道路をわかりやすく
  • 障害物をわかりやすく
  • cycleway=crossingを地味に
  • designated=yesを派手に
  • サイクリングマップの場合
    • 歩道で、なぜかbicycle=yesは実線なのに、segrageted=yesを付加すると点線で描画されてしまう
  • 相変わらずcycleOSMが定期的に重くなる・ダウンして読み込めなくなる

やり残したこと

• 規制変更で大規模に消去された自転車歩行者道の編集
• 普通自転車通行指定部分の編集
• 取り消されれつつある自転車横断帯、それっぽいのはまだ残っているが規制も残っているところはどのくらいあるのか
• 実地調査による、歩道とかスロープとかの障害物の記入

El proyecto de importación de desfibriladores (DEA) en Málaga ya está publicado y abierto a la participación de mapeadores locales. La coordinación se llevará a cabo desde el grupo local OSM Málaga, un grupo pequeño y cercano de mapeadores que conocemos bien la zona.

Esta importación llevaba tiempo pendiente dentro del plan de importación de datos abiertos del Ayuntamiento. He trabajado en adaptar el formato original y preparar los datos para su incorporación a OpenStreetMap. La revisión de la calidad de las ubicaciones se realizará durante la fase colaborativa, aprovechando el conocimiento local y la verificación sobre el terreno.

En importaciones anteriores basadas en datos abiertos municipales, el resultado final en OSM ha terminado siendo más completo y preciso que el conjunto de datos original, gracias al trabajo conjunto de la comunidad. La intención es que esta importación siga el mismo camino: no solo añadir datos, sino mejorarlos.

Quien quiera participar dentro del ámbito local puede consultar la documentación de la importación o unirse al grupo OSM Málaga.

Ayubowan from Sri Lanka,

My name is Hasna from Sri Lanka, and I bring over 3.8 years of experience in OpenStreetMap (OSM) and humanitarian geospatial work. I began as a self-learner with limited engagement, but my journey has evolved into sustained, impact-driven contribution at both national and global levels.

In 2022, I joined UNOPS Sri Lanka, where I worked within capacity-building initiatives for civil society organizations. In this role, I actively promoted OpenStreetMap, open-source GIS, and humanitarian mapping through HOT. Through the UNOPS Vriddhi Project, I directly trained over 100 civil society partners, strengthening local mapping capacity and enabling wider adoption of geospatial tools in development work. This experience grounded my understanding of how open mapping translates into real-world community impact.

A defining milestone in my journey was attending State of the Map 2025 in Manila. This experience significantly reshaped my perspective on the global humanitarian mapping ecosystem. It allowed me to connect with experienced mappers, mentors, and contributors, and establish a strong professional network. Since then, my engagement with HOT has become more structured, consistent, and purpose-driven.

Currently, I serve as the Country Lead for Sri Lanka under WOM Asia Navigators, where I support community engagement and capacity development in open mapping. Over the past seven months, I have completed more than 190 HOT tasks across disaster preparedness, disaster response, and recovery operations, demonstrating sustained technical contribution in humanitarian contexts.

What does HOT mean to you? HOT represents a global humanitarian ecosystem that transforms geospatial data into life-saving action. To me, it is not just a platform, but a collaborative force of mappers, organizations, and communities working to ensure that vulnerable populations are visible, supported, and included in disaster preparedness and response systems.

How did you become involved with HOT? My deeper involvement began after State of the Map 2025, where I witnessed the real-world scale and impact of HOT’s work. This motivated me to move beyond passive learning into active contribution. Since then, I have consistently engaged with HOT learning resources, mapping projects, and working group discussions, steadily increasing my contributions to over 190 tasks within seven months.

Why do you want to become a voting member? I am seeking to become a HOT voting member because I am committed to moving from contributor to active decision-support within the organization. I strongly align with HOT’s mission and believe my experience in training, community engagement, and field-level mapping can contribute to its strategic direction. Becoming a voting member will allow me to: -Strengthen my engagement in governance and community representation -Contribute more intentionally to HOT’s sustainability and growth -Support inclusive participation from the Global South, particularly Sri Lanka and similar contexts

Can you share your involvement in HOT, mapping, and humanitarian response? I have contributed to multiple humanitarian mapping initiatives focused on disaster preparedness, resilience, and response, including: Mozambique TC GEZANI 26 Massinga 1 Priority Mapping Initiative, Ngwata Missing Buildings and Road Mapping for resilience and smart city development, United Nations for Somalia - CEEL GADDE: villages and barriers, Missing Maps: Buildings in Aweil Counties, South Sudan, Disaster Response in North Sumatera Indonesia, Building Mapping. These experiences have strengthened my technical consistency, attention to detail, and understanding of crisis-informed mapping workflows.

As a voting member, what do you see as your most important responsibility? My primary responsibility as a voting member would be to actively safeguard and strengthen the quality, integrity, and sustainability of HOT’s humanitarian mapping ecosystem. This includes ensuring that community contributions remain both scalable and reliable, while continuing to serve real-world humanitarian needs.

How do you plan to engage with HOT as a voting member? Are there specific working groups you’re interested in joining? As a voting member, I plan to engage through consistent contribution, mentorship, and active participation in community and technical discussions. I am particularly interested in the Community, Technology & Innovation, and Training Working Groups, as they align with my experience in capacity building, geospatial learning, and community empowerment.

What do you see as HOT’s greatest challenge, and how would you help address it? One of HOT’s most critical challenges is maintaining a balance between the scale of mapping contributions and the sustained quality and reliability of data, while ensuring long-term community engagement. I would contribute to addressing this by: -Strengthening structured training and mentorship for new mappers -Supporting community-led capacity building, especially in underrepresented regions -Promoting best practices in humanitarian mapping workflows -Encouraging sustained engagement rather than short-term participation Through these approaches, I aim to help strengthen both the quality and sustainability of HOT’s global mapping ecosystem.

Thanks for reading, Cheers

Good day!

I’m Erika from the Philippines, an open mapping advocate and member of UPRI YouthMappers. I actively contribute to OpenStreetMap and humanitarian mapping initiatives that support disaster resilience, risk reduction, and community-based geospatial data. My journey with HOT began as a volunteer mapper through YouthMappers, participating in mapathons that create critical data for disaster-prone and vulnerable communities. Over time, I became a student leader in UPRI YouthMappers and later served as an Open Mapping Guru, helping train new mappers and support community programs within the HOT ecosystem. I also expanded my involvement in the broader open mapping community through local and international events such as Pista ng Mapa (Festival of Maps) and State of the Map. These experiences strengthened my appreciation for the power of collaboration, community building, and open geospatial data in addressing real-world challenges.

HOT Mapping Gurus during the State of the Map 2025

For me, HOT is more than a mapping organization. It is a movement of a global community that transforms volunteer contributions into meaningful humanitarian impact. As a voting member, I hope to support transparent and inclusive decision-making while representing the perspectives of youth mappers, grassroots contributors, and local communities. I am committed to remaining actively engaged and helping strengthen HOT’s global network.

If selected, I plan to actively participate in the Community and Training Working Groups. I am particularly interested in the Community Working Group, which works to strengthen collaboration across the global HOT network and support the growth of local mapping communities. I am also drawn to the Training Working Group, as training has been a core part of my experience, and I believe improving and consolidating training materials is essential to sustaining high-quality contributions and empowering new mappers.

One of HOT’s greatest challenges is sustaining long-term engagement while continuing to grow a diverse and globally representative community. I hope to contribute by supporting training and mentorship opportunities, particularly through YouthMappers and other community-led initiatives, helping new volunteers develop into active contributors, community members, and future leaders.

Looking back, I’m grateful for how the open mapping community has shaped my journey from being a student volunteer mapper tracing buildings during mapathons to training new contributors and engaging with mappers from around the world. As I continue this journey with HOT and the wider OpenStreetMap community, I look forward to learning, contributing, and helping more people discover the impact that open mapping can have on communities and humanitarian action.

Lists of such objects can be found on https://en.wikipedia.org/wiki/Cell_site#Wooden_structures , https://en.wikipedia.org/wiki/List_of_tallest_wooden_buildings_and_structures and https://en.wikipedia.org/wiki/Lattice_tower#Wooden_lattice_towers .

A possible further object may exist north of Kóspallag, Hungary at 47.8786466 N 18.9422987 E. However there are no pictures of this tower available. In the openstreetmap entries this object is classified as a hybrid structure of steel and wood, but Google Streetview shows it as a steel object, however it is barely visible there.

So someone should determine the exact type of this structure. It would be also a great idea, if someone could take a picture of this tower and upload it to Wikipedia, so everyone can see its type.

Further it would be great if Hungarian mappers can find out further wooden cellphone transmitters (past and present) in Hungary and add them to the list on https://en.wikipedia.org/wiki/Cell_site#Wooden_structures

I don’t normally think about the Sun’s direction when I go out running. When it gets exceptionally hot in summer, I start to notice it and wonder if I can tune my early morning run routes to experience slightly less heat. In principle, that should be possible. The position of the Sun can be worked out with a Python script. Combined with the angle of the Sun in the sky and your heading, it will tell you if you are running straight into the Sun or if the Sun is behind you. My personal preference is running towards the sunrise. After sunrise, you can call OSRM to optimize around solar load, defined as a function of Sun azimuth, your heading, and Sun altitude. This is probably over-engineering for route planning, though. The solar load has no simple formula, and the effect of clouds or humidity is hard to account for. Just a basic knowledge of civil dawn, sunrise time, and sunrise direction is probably enough for everyday running. But back to route generation — if you can find a metric to optimize for, you can generate new routes you have not run before. It is hard to define route novelty, but something like sun direction is easier to work with. The end goal would be to create routes that are different from what you can discover by simply using your street sense.

Geschichte und Motivation

Seit den ersten Schritten meiner OSM‑Reise liebte ich die Idee von Spielplatzkarten. Dafür gibt es mehrere Gründe, auf die ich hier nicht ausführlich eingehen möchte: offene Daten, Karten, FOSS – und natürlich die Kinder und ihre Freude (und … alle Eltern da draußen werden es sicherlich zu schätzen wissen, wenn ihre Kinder auf einem Spielplatz mit vielen anderen Kindern spielen 😉).

Es gab bereits einige Spielplatzkarten. Manche basierten auf OpenStreetMap‑Daten, andere nicht oder nutzten eine Mischung. Einige wirkten wie aus den 90ern, andere moderner. Oft mussten Nutzer:innen ein Konto beim Anbieter erstellen — oder, noch schlimmer, bei Google 🙈. Zudem wurden in diesen Fällen Fotos, Kommentare oder Bewertungen in deren Systemen gespeichert, und OSM diente lediglich als Kartenschicht, um Spielplätze anzuzeigen.

Selbst die Stadt, in der ich lebte, hatte ihre Spielplatzkarte an einen Cloud‑Dienst ausgelagert. Obwohl diese zumindest nicht schlecht aussah, umfasste sie nur 9 von rund 250 Spielplätzen im Gebiet …

Keine dieser Lösungen konnte mich überzeugen!

Dann entdeckte ich ein vielversprechendes Projekt in Berlin: die „Berliner Spielplatzkarte“ von Alex Seidel. Ich kontaktierte ihn, und es stellte sich heraus, dass dieses Projekt im Wesentlichen das war, wonach ich gesucht hatte.

Soweit ich mich erinnere, war es ein Prototyp zur Konzeptprüfung. Es fehlten noch einige Funktionen oder es gab ein paar Hindernisse:

• Keine Bildunterstützung
• Keine Bewertungsfunktion
• Nur Spielplätze in Berlin enthalten
• Keine Routenvorschläge zu Points of Interest (aus Sicht von Spielplatzbesucher:innen)

Auch wenn Alex meine Begeisterung für Spielplatzkarten teilte, hatte er letztlich keine Zeit, das Projekt weiterzuentwickeln.

Einige Monate später begann meine Reise — ich forkte sein Projekt …

Was ist Spieli?

Zunächst einmal: Es ist ein perfekter Domainname – leicht zu merken: spieli.eu

Besonderer Dank gilt Ronny für seine Unterstützung bei der Namensfindung für das Projekt und für seine wertvollen Beiträge zu verschiedenen Diskussionen über die Architektur.

Linguistische Aspekte

Aussprache: [ˈʃpiːli]

Bedeutung/Definition:
Ein deutsches Wort, das typischerweise eine Fläche für Kinder beschreibt, die oft mit verschiedenen Spielgeräten ausgestattet ist.
Verwendung: Kindersprache.

Artikel/Genus:
Im Deutschen ist der grammatikalische Genus maskulin: „der Spieli“.
Im Englischen wird es als sächliches Substantiv verwendet: „the spieli“.

Allgemein

Eine kostenlose, interaktive Webkarte zur Erkundung von Spielplätzen basierend auf OpenStreetMap‑Daten.

Das klingt nicht morz revolutionär, oder? Aber ich behaupte: Ist es aber!

1. Er ist nutzer:innenfreundlich gestaltet – für Eltern, Großeltern. Die Oberfläche ist sauber, einfach und super benutzerfreundlich. Es wird keine App benötigt – nur eine Website und es sind keine Logins erforderlich.
2. Es ist nicht nur eine Karte. Es handelt sich um ein Föderationsprojekt: Es funktioniert als Netzwerk unabhängiger Knoten (Datenknoten), die Daten an einen zentralen Hub (Hub‑Modus) übermitteln. Dies ermöglicht dezentrales Hosting und Skalierbarkeit. Es kann in verschiedenen Modi betrieben werden:
   • Ein Hub-Modus, der lediglich die Webseite/Karte darstellt.
   • Ein Datenknoten-Modus, der OSM‑Daten für bestimmte Regionen bereitstellt (z. B. Relationen).
3. Es nutzt ausschließlich freie und offene Daten:
   • OSM‑Daten für Spielplätze,
   • Panoramax für Bilder,
   • Mangrove Reviews für Bewertungen.

Ich scherze oft, dass der erste Punkt es einzigartig macht … und das ist sowohl ein Scherz als auch nicht. Bei vielen Open‑Source‑Projekten sieht man dieses Muster: ein fantastisches Backend, aber niemand kann es nutzen, weil das Frontend fehlt oder schlecht designed ist. Das sollte hier nicht der Fall sein!
Aber ich denke, die Punkte 2 und 3 sind bei Spielplatzkarten ebenfalls eher selten.

💡 Der Grund für dieses dezentrale Setup ist einfach: Ich liebe die Idee der Zusammenarbeit und die Mentalität „Gemeinsam sind wir stärker“. Außerdem reichte mein Budget nicht aus, um die gesamte Weltkarte auf meinem eigenen Server zu hosten 😅.

Die spieli.eu‑Instanz hostet aktuell einen Hub mit 16 Datenknoten, um ganz Deutschland abzudecken. Die Datenknoten für Baden‑Württemberg und Niedersachsen werden von anderen Personen auf deren eigenen Servern gehostet.

Trete der Spieli‑Community bei!

Mein VPS kommt an seine Grenzen, da ich derzeit 14 Backends darauf hoste 🤯. Ich wäre sehr dankbar, wenn andere bereit wären, ein Backend für ein deutsches Bundesland zu hosten. Das würde nicht nur die Last meiner Infrastruktur verringern, sondern auch das dezentrale Konzept des Projekts stärken.

Ich würde mich auch riesig freuen, Spieli international auszubauen. Möchtest du die Spielplätze deines Landes einbinden? Interessierst du dich dafür, die Spielplätze deines Landes hinzuzufügen? Lasst uns zusammenarbeiten!

Alternativ kannst du Spieli auch einfach für dein Land oder deine Region hosten.

The Spieli

History and Motivation

From the very beginning of my OSM journey, I loved the idea of playground maps. There are several reasons for this, but I won’t go into detail here. For example: open data, maps, FOSS, and, of course, the children and their joy (and… all the parents out there will surely appreciate it when their children play at a playground - ideally with plenty of other kids 😉).

There were already some playground maps available. Some were based on OpenStreetMap data, others were not, or used a mix of both. Some looked like they were designed in the 90s, while others did not. In many cases, users were required to create an account with the maintainer’s service—or, even worse, with Google 🙈. Additionally, in these cases, photos, comments, reviews, and so on were stored in their systems, and OSM was only used as a map layer to display playgrounds in general.

Even the city where I lived outsourced its playground map to a cloud service. Even though this one at least didn’t look terrible, it only included 9 of the ~250 playgrounds in the area…

I wasn’t satisfied with any of these solutions!

Then I discovered a promising project in Berlin: the “Berliner Spielplatzkarte” by Alex Seidel. I chatted with him, and it turned out that this project was essentially what I had been looking for.

If I recall correctly, it was a prototype to test the concept. There were still some features missing or blockers:

• No picture support
• No review support
• Only included playgrounds in Berlin
• No routing suggestions to POIs (from a playground visitor’s perspective)

Even though Alex shared my enthusiasm for playground maps, he ultimately didn’t have the time to continue working on the project.

A few months later, my journey began—I forked his project…

What is Spieli?

First of all: It’s a perfect domain name - easy to remember: spieli.eu

Special thanks to Ronny for helping shape the name of the project and some valuable input to several architectural discussions.

Linguistic Aspects

Pronunciation: [ˈʃpiːli]

Meaning/Definition: A German word typically used to describe an area for children, often equipped with various play facilities or devices. Usage: Children’s language.

Article/Gender: In German, the grammatical gender is masculine: „der Spieli.” In English, it is used as a neuter noun: “the spieli.”

General

A free, interactive web map for exploring playgrounds based on OpenStreetMap data.

This might not sound particularly groundbreaking, right? But I claim it is!

1. It is designed for users - parents, grandparents. It has a clean, simple, and super user-friendly interface. No app required — just a website, and no logins are necessary.

2. It’s not just a map. It is a federation project: It operates as a network of independent nodes (data-nodes) that contribute data to a central hub (hub mode). This allows decentralized hosting and scalability. It can operate in different modes:
   • A hub mode, which is just the web page/map.
   • A data-node mode, which provides OSM data for specific regions (e.g., relations).
3. It only uses free and open data:
   • OSM data for playgrounds,
   • Panoramax for pictures,
   • Mangrove Reviews for ratings.

I often joke that the first point makes it unique… which is both a joke and not. In many open-source projects, you see this pattern: a fantastic backend, but no one can use it because of a missing or poorly designed frontend. This should n’t be the case here! But I think points 2 and 3 are also quite rare when it comes to playground maps.

💡 The reason for this decentralized setup is simple: I love the idea of collaboration and the “together we’re stronger” mentality. Plus, I didn’t have enough money to host the entire world map on my own 😅.

The spieli.eu instance hosts a hub with 16 data-nodes to cover all of Germany. The Baden-Württemberg and Lower Saxony data-nodes are hosted by other people on their own servers.

Features

User’s Perspective

• Suggestions for nearby playgrounds
• Filter playgrounds (e.g., by equipment, surface, or accessibility)
• Suggest nearby POIs that might interest playground visitors (🍦!!!)
• A data quality rating for each playground → Contribute with just one OSM account 💪
• General information about playgrounds (surface, opening hours, operator, etc.)
• Pictures of the playground and each piece of equipment
• Mangrove Reviews and ratings
• Support for sports pitches (e.g., soccer, basketball, skating) even outside playground areas
• Support for fitness stations

OSM Contributors / Maintainers’ Perspective

• Support for the common playground mapping rules
• MapComplete 💖 links to add devices or pictures
• Supports mapped devices both separately and within playground areas
• Automatic app updates using Watchtower
• Automatic database updates
• Traefik, which handles SSL certificates via Let’s Encrypt
• Prometheus endpoint for monitoring
• A straightforward solution for legal/imprint pages.
• AI-supported development :see_no_evil: - A wide variety of AI systems can be used

Join the Spieli Community!

My VPS is running out of memory soon, as I’m currently hosting 14 backends on it 🤯. I would greatly appreciate if others were willing to host a backend for a German state. This would not only ease the load on my infrastructure but also strengthen the decentralized nature of the project.

I would also be thrilled to expand Spieli internationally. Want to include the playgrounds of your country? Interested in adding your country’s playgrounds? Let’s collaborate!

Alternatively, feel free to host it just for your country or region.

Whenever I have some time, I keep improving OSM Spyglass. A very useful addition is that Spyglass now shows suggestions for the key and value filter fields. Spyglass gets possible keys/values from the data currently loaded and will show all keys/values matching what you have typed so far.

There are many other small improvements in the UI, one is a new menu option in the location control: Switch lat/lon. Very useful when you have a system that shows the coordinates the other way around from what OSM Spyglass expects (for instance QGIS). Just copy and paste the coordinates, Spyglass will jump to the wrong location, but one click later you are at the right spot.

There are many internal changes also. There is support now for storing OSM object attributes (version, changeset, timestamp) with the data. (No support for user ids or user names so far.) Attributes are currently not enabled on the version running on spyglass.jochentopf.com to save some disk space and import time, and they are not shown in the UI anyways. More work for the future…

There are also plenty of changes with the database tables, how I am organizing the data internally. I am trying out various formats to minimize storage and make queries more efficient and/or easy to use. The biggest change is that I switched from using JSONB for the tags to that old classic, the hstore format. JSONB and hstore are quite similar for what we are doing here, but there is one big difference: It is possible to create a GIST index that combines geometry and tags when using hstore making queries with key/value filter somewhat faster.

Another area I have been experimenting with is how to detect and display “unusual data”. Unusual data in this case are things like ways that contain only a single node, or ways having duplicate nodes in them, relations without type tag or without members and so on. So we are talking about some low-level errors in the data, that I want to detect and show to the user in a useful way, so that they can figure out why some object is not showing up properly in the map. Single-node ways, for instance, would usually not be visible, because you can’t have a line with only one point in it. So this case is detected and the way shown as black point with an orange center. When selected, the way is shown with a message “Way contains only a single point!”.

Some other “unusual” cases are currently detected and the information is in the database but now shown yet.

iD tagging schema is a recording of various information about OpenStreetMap tagging. It is done in format allowing it to be both machine-readable and human-readable.

There are various ways how it can be improved, some relatively complex, some very easy.

We have list of things that should be fairly easy to implement

If anyone is interested in contributing - it could be a good start and I can promise quick review, if they would be implemented by someone.

This changes will be quite easy to write, it is not a programming - it is rather editing a relatively simple config file. But they still need to be tested, which actually takes most of the time. And if editing config file is not a very scary task and https://en.wikipedia.org/wiki/JSON#Syntax is not terrifying, then you have a good chance to be able to do it.

Review afterwards should be quick like for another group of simple tasks

If you would be interested in helping with iD tagging schema, and you have any amount of technical ability… But this supposedly simple tasks are not obvious, feel free to ask here for help and I can guide you to your first PR.

Even if you never did anything with git/github etc, this could be a good start. And maybe you would later implement a more complex task

Hello OpenStreetMap community,

My name is Micheal Kaluba (OSM username: Michea Kal), and I am honored to be nominated for voting membership in the Humanitarian OpenStreetMap Team (HOT).

My journey with HOT began around 2016 through the Malaria Elimination Project and continued through my work with OpenStreetMap Uganda, where I served as a Field Mapping and GIS Training Associate for about six years. I currently serve as the Executive Director of Wikimedia Community User Group Uganda.

Over the years, I have been involved in mapping, field data collection, project management, capacity building, and community development initiatives across Uganda and South Sudan. Through collaborations with OpenStreetMap Uganda, Wikimedia Uganda, and other partners, I have contributed to humanitarian mapping projects, community training, and open data initiatives.

I have also participated in several international mapping conferences and community events, including State of the Map conferences in Germany, Côte d’Ivoire, Tanzania, the United States, and Kenya. These experiences have strengthened my commitment to open mapping, local leadership, and community-driven development.

To me, HOT represents the power of volunteers, communities, and organizations working together to make geographic information accessible where it is needed most. I believe in HOT’s mission and would like to contribute more actively to its governance and future direction as a voting member.

As a voting member, I hope to support inclusive decision-making, accountability, and stronger representation of communities from underrepresented regions. I also look forward to contributing to community and training initiatives within HOT.

I believe one of HOT’s greatest challenges is balancing global humanitarian impact with strong local community ownership. Addressing this requires continued collaboration with local OpenStreetMap communities, investment in capacity building, and support for community-led initiatives that create sustainable, long-term impact.

Thank you for your time and for the opportunity to be part of this amazing community. I look forward to continuing to contribute to HOT and the broader OpenStreetMap ecosystem.
