Public Test Instance Launch 🚀

• 🗺️ Public Instance (osm.ng)
• 📖 Testing Guide

OpenStreetMap-NG is now live for public testing at osm.ng. This milestone represents months of intensive development, optimization, and preparation to create a stable testing environment for the community. Every mapper, developer, and OpenStreetMap enthusiast can now experience what we’ve been envisioning as the next generation of mapping platforms.

The test environment runs completely independently from the main OpenStreetMap infrastructure. It features the complete OpenStreetMap dataset while providing a safe playground for experimentation and feedback. You can explore all the functionality without worrying about affecting live data—perfect for giving the platform a thorough evaluation.

Liftoff! We have a liftoff, 32 minutes past the hour. Liftoff on Apollo 11.

CloudFerro Infrastructure Partnership

We’re grateful to CloudFerro for generously sponsoring the server infrastructure that powers osm.ng. We deliberately chose a medium-specification server (30GB RAM, 4 CPU cores; they offered more) for a specific reason: to make performance bottlenecks and optimization opportunities clearly visible during testing. This strategic approach ensures that subtle bugs or inefficiencies don’t slip through due to overpowered hardware masking underlying issues. By testing on realistic hardware constraints, we can identify and resolve problems before they affect users more broadly.

Scalability Improvements

OpenStreetMap-NG now demonstrates exceptional scalability across diverse hardware configurations, thanks to extensive optimization work enabled by our test server access. The platform intelligently adapts to whatever resources are available, maximizing performance across different setups.

Memory scaling now works beautifully from 20GB RAM (the realistic minimum) all the way up to 128GB+ configurations. Processing adapts seamlessly from 4 CPU threads to 32+ core systems. Storage optimization handles everything from high-latency SSDs to directly-connected NVMe drives, dealing effectively with various bandwidth and latency conditions. This means OpenStreetMap-NG is accessible to organizations with modest infrastructure while still taking full advantage of powerful hardware when it’s available.

Dataset Loading Optimizations

Developer experience received a substantial boost through dramatic improvements in dataset loading performance. Initial local database pre-loading time dropped from 20 minutes to just 4 minutes—a remarkable 5x improvement while handling the same data volume! These kinds of optimizations remove friction from the development workflow, letting contributors iterate faster and experiment more freely with OpenStreetMap-NG’s hackable architecture.

Performance Engineering

The introduction of the speedup Python C extension revolutionizes performance-critical operations by implementing them in optimized C code. This delivers substantial performance improvements across multiple system components.

We’ve also significantly optimized memory usage through several architectural changes. XML parsing now uses 75% less RAM thanks to string interning and SAX-style parsing, eliminating memory pressure during replication processing on our test server. Database objects were completely reimagined by removing SQLAlchemy abstraction layers in favor of pure Python dictionaries with TypedDict typing safety. This makes the entire platform more efficient across all operations.

Features and Stability

The public test launch includes several user-facing improvements that really enhance the experience. Dark mode support provides comfortable viewing in low-light conditions, while the new language selector improves accessibility for non-logged-in users across different locales. We’ve also implemented comprehensive stability improvements addressing various bugs identified during development.

Before going public, we ran a two-week intensive testing phase with our Discord community members. This helped ensure stability and catch critical issues before the public announcement—having that extra set of eyes made all the difference.

What Caused the 6-Month Delay?

We know many of you have been waiting patiently, and we want to be transparent about why this took six months. The delay reflects the genuine complexity of optimizing OpenStreetMap-NG for production-scale deployment. Scalability turned out to be the primary technical challenge, requiring careful architectural decisions to balance performance with resource constraints.

Memory management proved particularly tricky. We needed to find optimal allocation strategies for large datasets while maximizing efficiency on limited hardware. Each architectural change required extensive validation with full datasets, and sometimes the smallest modifications could produce week-long delays. The iterative optimization process was time-consuming, but it resulted in a fundamentally more robust platform that we’re confident can handle real-world deployment scenarios.

Earn Rewards 🎁

We’re launching something new: a bounty program to recognize valuable community contributions during the testing phase. We’re offering $5 for quality feedback that leads to improvements, limited to the first 100 qualifying testers. The top 10 most valuable contributions will get an additional $5 bonus, bringing their total reward to $10.

We’re especially interested in reproducible bug reports, performance issues, visual glitches, accessibility problems, and security concerns. But general usability feedback, feature improvement suggestions, and API compatibility issues for developers are also incredibly valuable.

Learn more about the bounty program.

The Future

With the test instance fully operational, OpenStreetMap-NG enters an exciting new phase focused on community feedback and refinement. The hackable system design philosophy we’ve built in enables rapid experimentation and component swapping, encouraging innovative approaches to mapping platform challenges.

We’re committed to integrating community feedback—incorporating tester suggestions and bug reports into ongoing development. We’ll also be monitoring performance closely, analyzing usage patterns to identify new optimization opportunities. This testing phase is more than just technical validation—it’s an opportunity for the OpenStreetMap community to help shape the platform’s future direction through hands-on experience and constructive feedback.

OpenStreetMap went viral! Well, sort of.

A recent Instagram video highlighted an area where Pokémon Go had better trail coverage than Google Maps. You can see for yourself:

Original Instagram Post

OSM Town Mastodon Mirror

Currently, the video has over 12.6 million views and 733 thousand likes!

As you probably know, Pokémon Go uses OSM for it’s map data. So it’s cool seeing it acknowledged that OSM data performed better, even if it was misguided as a compliment towards Pokémon Go/Niantic.

With a little bit of searching, I found the path that they were on: Way #518694188. Added 8 years ago by BikeRoad.

Hallo,

ich konnte nichts finden und habe auch noch keine gute Idee wie man das hier mappt:

Working independently to help plot missing areas but conscious of the current geopolitical situation. Can anyone recommend if there’s any areas to be mapped out of urgency? For instance Texas with the current floods, Gaza or Ukraine etc for the humanitarian issues and destruction of war. I want my work to have as much positive impact and possible and consequentially don’t want to be plotting somewhere remote in say Africa for instance when actually somewhere else is in a much more urgent and desperate need. Many thanks.

Vom 2. bis 3. Juli fand in Salzburg die jährliche AGIT-Konferenz für Geoinformatik statt. Unter dem Motto „Shaping Geospatial Futures“ versammelten sich mehrere hundert Besucherinnen und Besucher aus dem deutschsprachigen und internationalen Raum. Auch wenn ich nicht jedes Jahr dabei war, zeigt ein Blick in meine Unterlagen: Mein erster Beitrag auf der AGIT (ein Poster) stammt aus dem Jahr 2005. Ein 20-jähriges Jubiläum also? Verrückt, wie die Zeit vergeht. In diesem Jahr hatte ich die Gelegenheit, die Ergebnisse der Masterarbeit von Pauline Radu zu präsentieren. Im Wintersemester hatte sie sich im Rahmen ihrer Abschlussarbeit mit Daten des Landeskriminalamts Rheinland-Pfalz beschäftigt. Mit dem Titel ihrer Arbeit: „Möglichkeiten und Potenziale von Retrieval-Augmented Generation für die räumliche Analyse von Kriminalitätsdaten“ konnte somit ein hochaktuelles und praxisnahes Thema in Salzburg gezeigt werden.

Anbei ein Auszug aus der Publikation ihrer Arbeit: “Die steigende Komplexität und Sensitivität der Kriminalitätsanalyse erfordert innovative Ansätze, um präzise Einblicke zu gewährleisten. Dieser Beitrag untersucht das Potenzial der Retrieval-Augmented Generation (RAG) für die Analyse von Kriminalitätsdaten unter besonderer Berücksichtigung deutschsprachiger Texte. RAG integriert fortschrittliche Natural Language Processing (NLP) Techniken mit Retrieval-Modulen, um kontextreiche Antworten auf spezifische Fragen zu generieren. Anhand eines prototypischen RAG-Systems, implementiert mit polizeilichen Falldaten aus Rheinland-Pfalz, werden Möglichkeiten und Herausforderungen für die räumliche Analyse untersucht. Ergebnisse zeigen, dass das System präzise in der Identifizierung von Tatort-Hotspots und der Analyse von Deliktmustern agiert, jedoch Herausforderungen in der Konsistenz und Abdeckung räumlich breiter Phänomene aufzeigt. Durch Feintuning und verbesserte Datenintegration könnte RAG zukünftig eine robuste Unterstützung für die Kriminalitätsanalyse bieten.” Der Fulltext des Beitrags ist unter folgender DOI zu finden: doi.org/10.25598/agit/2025-14

Ein kleines Augenzwinkern am Rande: Mein Vortrag begann mit dieser provokanten Folie – „RAG is dead. Long live agentic retrieval!?“ Mit dieser Aussage wollte ich auf die rasante Entwicklung im Bereich der KI-basierten Informationssysteme anspielen. Während RAG in vielen Anwendungen noch als innovativ gilt, wird in der Forschung bereits über den nächsten Schritt diskutiert: sogenannte „agentic retrieval“-Ansätze, bei denen autonome Agenten gezielt, adaptiv und kontextsensitiv Informationen beschaffen. Ob es sich dabei nur um ein Buzzword oder um den Beginn einer Paradigmenverschiebung handelt? Wir werden sehen

Vielen Dank an dieser Stelle für das positive Feedback und die Fragen im Anschluss und in den Kaffeepausen – hat mich wirklich gefreut.

OSM모임이나 협회 같은거 우리나라에도 있으면 좋겠다 바로 옆나라 일본도 있던데

Newborough has been fully micromapped, that includes: powerlines, street lights, street trees and underground fire hydrants. Roads have been edited and instead of basic lines, they now follow the center point of the road perfectly.

Seit dem Frühjahr 2020 gibt es in Deutschland ein neues Verkehrszeichen: den Grünpfeil nur für Radfahrende. Es erlaubt Radfahrenden, auch bei roter Ampel nach rechts abzubiegen. Ich habe mich gefragt, ob ich mit Hilfe von OpenStreetMap automatisch Stellen raussuchen kann, bei denen die Aufstellung so eines Zeichens sinnvoll wäre.

Wo sind solche Zeichen sinnvoll?

Wenn ich meine persönliche Erfahrung und die gesetzlichen Vorgaben (StVO, VwV-StVO) zusammennehme, ist der Grünpfeil für Radfahrende vor allem in dieser Situation sinnvoll: Wenn ich aus einer Wohnstraße komme (kein Radweg vorhanden) und rechts auf eine Straße einbiegen will, die einen abgetrennten Radweg hat. Da ich hier nur auf querenden Fuß- und Radverkehr achten muss, ist ein sicheres Abbiegen nach rechts auch bei rot in der Regel möglich.

Overpass-Query finden.

Ich will die Abfrage nicht zu kompliziert machen, aussortierne kann ich ja immer noch. Ich will also wissen, wo Ampeln auf Wohnstraßen stehen, bei denen im Umkreis von 10 Metern ein Radweg oder ein getrennter Rad-/Fußweg existiert.

Die gesuchten Merkmale lassen sich so in OSM-Tags fassen:

• Die Ampel ist ein node mit highway=traffic_signals
• Sie liegt auf einer way mit highway=residential
• In der Nähe (max. 10 m) existiert ein:
  • way mit highway=cycleway
    oder
  • way mit highway=path und bicycle=designated und segregated=yes

Mithilfe von ChatGPT (ja, ich weiß, aber ich finde die Overpass-QL echt schwierig), habe ich diesen funktionierenden Query gefunden:

[out:json][timeout:25];

// 1. Wohnstraßen und zugehörige Ampeln
way["highway"="residential"]({{bbox}})->.residentials;
node(w.residentials)["highway"="traffic_signals"]->.signals;

// 2. Radwege nach OSM-Tagging-Standards
(
  way["highway"="cycleway"]({{bbox}});
  way["highway"="path"]["bicycle"="designated"]["segregated"="yes"]({{bbox}});
)->.cycleways;

// 3. Finde Ampeln, die innerhalb von 10 m zu einem Radweg liegen
node.signals(around.cycleways:10)->.relevant_signals;

.relevant_signals out center;

👉 Abfrage in Overpass Turbo öffnen

Und jetzt?

Als nächten Schritt werde ich die Ergebnisse für meine Heimatstadt auswerten (tatsächliche Eignung mithilfe von Mapillary oder Sichtung vor Ort prüfen) und anschließend bei der Verwaltung anregen, an diesen Stellen diese Schilder aufzustellen.

I notice all across China that bots have destroyed powerlines and now they are missing many segments that were previously complete.

J’ai eu l’honneur de participer en présentiel à la première conférence State of the Map Global 2024 organisée en Afrique, au Kenya. Cette expérience a été marquante et enrichissante, me permettant de rencontrer de nombreux acteurs passionnés engagés dans divers projets. Bien que je sois la seule représentante du Bénin, je me suis sentie pleinement intégrée dans cette dynamique internationale. Retrouver des amis de la communauté Wikimedia à SotM a été une agréable surprise.

Les sessions, présentations et ateliers étaient d’une qualité exceptionnelle. Bien que je n’aie pas animé d’atelier cette fois-ci, je suis plus déterminée que jamais à le faire lors des prochaines éditions. J’ai particulièrement apprécié les interventions sur l’égalité des genres, notamment celle d’Anastazia Caroll sur Women in OSM Tech, ainsi que celle de Bénédicta, qui a mis en lumière les perspectives de la participation des femmes dans OpenStreetMap. La réunion des membres votants de HOT m’a permis de rencontrer le président et d’autres membres de l’organisation. Ce fut une occasion précieuse d’échanger des idées et de mieux comprendre les dynamiques internes de HOT. Ces interactions ont renforcé mon engagement au sein de la communauté et m’ont permis de nouer des relations professionnelles significatives.

Je tiens à exprimer ma profonde gratitude à OSM Kenya et au groupe de travail de SotM pour l’organisation exceptionnelle de cet événement, ainsi qu’à HOT pour m’avoir accordé cette bourse qui m’a permis de vivre cette expérience unique. Un immense merci également à l’équipe organisatrice et aux bénévoles, qui ont fait de cette conférence un véritable succès. Je suis pleinement motivée à poursuivre mon engagement et à jouer un rôle plus actif lors des prochaines éditions.

Rendez-vous à Manille pour SotM 2025 !

جبل مرغم علي التاريخي

يعد جبل مرغم علي أحد المعالم التاريخية والأثرية البارزة في قرية ضريبة العرش اليمنية، حيث يحمل بين صخوره آثارًا تعود إلى عهد الدولة الحميرية. يقع هذا الجبل في موقع استراتيجي، إذ كان يستخدم كحصن دفاعي لحماية قلعة الملك الحميري شمر يَهرعِش، التي تبعد عنه حوالي 9 كم في مدينة رداع. #### المعالم الأثرية رغم مرور الزمن، لا تزال بعض بقايا القلاع الحميرية قائمة على قمة الجبل، مما يدل على براعة الهندسة العسكرية في ذلك العصر. هذه القلاع كانت مبنية من الحجارة الصلبة، مما ساعدها على الصمود أمام عوامل الطبيعة لقرون طويلة. #### الموقع الجغرافي والطبيعة يتميز جبل مرغم علي بتضاريسه الوعرة وارتفاعه الذي يوفر إطلالة رائعة على المناطق المجاورة. كما أن موقعه يجعله نقطة جذب للباحثين في التاريخ والجغرافيا، حيث يمكن للزوار استكشاف بقايا التحصينات القديمة والاستمتاع بجمال الطبيعة المحيطة. #### أهمية الجبل في السياحة والتراث يعد هذا الجبل من المواقع التي يمكن أن تسهم في تنشيط السياحة التاريخية في اليمن، خاصة لمحبي الآثار والتاريخ القديم. فهو جزءًا من مسار سياحي يشمل قلعة شمر يَهرعِش وقرية موكل وغيرها من المواقع الحميرية في المنطقة

Lange habe ich gedacht, dass dieses Tag durch PTV2 überflüssig werden wird, bis ist gemerkt habe dass es notwendig ist.

Das Tag “highway=bus_stop” (nur zulässig auf Knoten) ist nicht veraltet. Es ist notwendig damit die Bushaltestelle in vielen Karten dargestellt wird. Z.B.: auf der Standardkarte openstreetmap.org

Im Wiki steht auf der Seite Tag:highway=bus_stop in der Spalte “Verwendung” nur “Kompatibilität”. Die mehr als 10 Jahren von PTV2 haben aber gezeigt, dass das Tag weiterhin gebraucht wird.

Es müsste “verpflichtend” heißen. (Auf der englischen Seite heißt der Eintrag auch Required)

no se que poner jaja

Activities Performed

• Participated in ‘‘transmission grid planning’’, applying surveying and cartographic principles to infrastructure development.
• Conducted line routing and selection exercises, evaluating terrain and land use for optimal transmission line alignment.
• '’Collected and recorded coordinates’’ using GNSS equipment to support planning and line diversion strategies.
• Assisted with **line diversion assessments by integrating spatial analysis and route optimization techniques.
• Engaged in GIS-based mapping and spatial data management for transmission corridors and project layouts.
• Supported **drawing office tasks including drafting, editing, and refining technical layouts for transmission lines using AutoCAD and GIS software.
• Contributed to the preparation of survey reports*, integrating observations, geospatial data, and recommendations for planning documentation.

Skills Applied

• Georeferencing and symbology in GIS
• AutoCAD drafting and technical alignment
• Thematic layering and map production
• Field coordination using QField and GNSS tools
• Formal report writing and spatial data interpretation

Today’s tasks deepened my understanding of how surveying and cartographic techniques drive transmission infrastructure planning. The integration of GIS with field activities reaffirmed the importance of spatial accuracy in energy distribution networks. I was particularly engaged with the line diversion analysis, which challenged both technical reasoning and spatial decision-making. I continue to learn from my mentors and refine my approach to precision mapping and collaborative survey documentation.
