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.

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.

Radio and communication towers made of wood are rare. 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.

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.

We more experienced mappers realize fast that OSM Carto is just meant to show off the capabilities of the database. So many takes I have seen “I did it becuase if I did it another way (which would be the conceptual better way, also documented on the wiki) it wouldn´t show up on https://www.openstreetmap.org…”

I am launching

• github.com/HuggeK/golfTiles
• golfTiles.org

As an open source project to first generate golf-centric PMtiles to help the mapping and application who wants to display world wide coursemaps. Then move on to at least daily updates to help mappers.

Help wanted if you want to try it out!

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.

This is a summary of the problem and a proposal regarding inconsistent treatment of greenery in sidlisko areas in Bratislava, Slovakia. Some arguments stem from my own experience with mapping these, some echo those I saw in various changeset comments. The following text is likely not exhaustive and I invite anyone concerned with the matter or area in question to join in discussion.

The subject

Greenery areas around blocks of flats on Bratislava’s sidlisko areas are specific. They’re typically grass, but often also with trees, benches, bins and play structures within them, all of it somewhat regularly maintained. I’ll call these areas panelak greenery for the remainder of this text.

The motivation

I began micromapping Karlova Ves and simply found that when adding detail up to splitting landuse on roads, using leisure=park becomes problematic. While leaving it mapped as huge blobs of leisure=park is an option, it’s a very rough approximation which doesn’t describe these areas in detail, which then defies the point of micromapping.

 The problem

The subject as described above implies usage identical to that of a park, and indeed, leads one to consider that leisure=park is technically the right tag for such areas. It is also apparent that these areas are not parks in the traditional sense of being compact areas dedicated to leisure and intended for the wide public. Since this is a bit of an instinctive classification, I’ll try to break it down into particularities. What differentiates these areas from parks follows:

Hello,

Below I have compiled recent news related to the OSM Foundation (OSMF) board’s work. Most of these are or are going to be publicly documented on the OSMF website, so if you follow the Atom feed for the board meetings’ page, you can skip this.

What this diary entry is

It contains my personal selection and recollection of recent OSMF board-related updates.

What this diary entry is not

It is not intended to include details or all OSMF board-related updates. For these, you can refer to the published board minutes. This entry has not been reviewed by the OSMF board.

Why?

Informing the OSMF members is important. The board minutes describe in detail what was discussed in public board meetings, but many people don’t have time or follow the Atom feed for the OSMF’s website recent changes. At some point, I was creating annual or more frequent updates for the whole Foundation, which was a lot of work during a short period, while other tasks were ongoing.

I’m posting this experimentally, and I’m going to see whether I can continue to do so semi-regularly.

May 2026 OSMF board updates

The board had a meeting on Thursday, 28 May 2026.

Draft minutes are here and they include minutes of the Chairperson’s report by Craig Allan and the Secretary’s report by Dani Waltersdorfer.

Some highlights are below.

Disputed territories

Rewriting the information for officials and diplomats of countries and entities with disputed territories
Craig Allan (OSMF Chair) has drafted a revision of the document for officials and diplomats of countries and entities with disputed territories, which was approved in September 2013, and which is referred to by the Data Working Group (DWG) and the OSMF. Craig circulated the draft to the board for feedback and suggested to Simon Poole (former OSMF Chair, former LWG Chair and present during the May 2026 board meeting) to review the updated policy document.

I came to know about this brilliant piece of software about a year ago. This has made me feel fresh, and happy. At first I was just roaming around the world, seeing different things like roads, buildings, parks etc.. They felt very different from google maps, because they were highly detailed. With information such as road lanes, speed limits, road surface, type, who made it, when was it made, when was renovated and stuff. I found a goldmine of data, but for maps). Then I saw my area. Well, I was really disappointed that nothing was there except the main road. Literally not even the names of the villages. Comparing to other countries it was nothing,like comparing a super-car with crying baby! My heart was demolished. So, I decided to make my area great in OSM.

But here is a twist, Whatever you think I added 1st is not true. The 1st thing I added was the Transmission line. IDK why I added it fist, but after that I added a lot of things like, Roads, Streets, parks, Trees, local power distribution lines and poles, with sewage line, the pond, also added businesses, corrected road names, resolved 2 to 4 year old messages. And now my village is the most detailed village in my district until someone else decides to map his area.

Before ending this post. I want to say: Happy Mapping! :)

My engagement with OpenStreetMap began through my involvement as a YouthMappers volunteer, where I developed a strong interest in the power of open geospatial data for development and humanitarian action.

Calvin Amevienku is my name, a YouthMappers volunteer regional ambassador to Ghana. I have had the opportunity to support and connect student chapters, promote mapping activities, and encourage youth participation in open mapping across my region and beyond. This role has deepened my understanding of how collaborative mapping contributes to capacity building, digital transformation and community resilience.

Through my continued involvement with the Humanitarian OpenStreetMap Team (HOT), I have contributed to humanitarian mapping efforts that support data availability for underserved communities and crisis response. These experiences have strengthened my appreciation for the role of volunteers in building and maintaining high-quality open geographic data.

Being nominated as a 2026 HOT Voting Member is both an honour and a responsibility that aligns closely with my work as a YouthMappers Regional Ambassador. It represents a transition from active contribution to meaningful participation in governance and decision-making within the HOT community.

If selected, I aim to represent the perspectives of YouthMappers and regional contributors, particularly from Africa, ensuring their voices are reflected in HOT’s decisions. I am especially interested in strengthening youth engagement, supporting local chapters, and advancing capacity building initiatives that sustain long-term participation in open mapping.

I am committed to contributing constructively to HOT’s governance processes and to strengthening collaboration among HOT, YouthMappers, and local mapping communities worldwide.

Cheers!

Для того, щоб будівля була схожа на реальну її краще малювати по даху, потім дивитися на два зображення супутника (наприклад ersi) і перетягувати полігон до фундаменту.

Для того что бы здание походило более на реальное его лучше рисовать по крыше, затем смотреть на два изображение спутника (наприклад ersi) и перетаскивать полигон к фундаменту.

To make the building look more like a real one, it is better to draw it on the roof, then look at two satellite images (for example, ersi) and drag the polygon to the foundation.

I recently discovered this. You can survey for Open Street Map easy if you use your camera with location tags turned on. Take lots of pictures of anything that could be added or updated while you shop, walk or drive. Then later you can go through your pictures and use the location to find where they were taken. Compare the location tag against satellite images, and add everything you find useful in your photos.

I recently went on a trip and I’m adding businesses, addresses, stop signs, speed limits to OSM this way and its really helpful. Ive been able to add so much more details that I didn’t even know I saved in my photos. Try it!
