Today, panning in Kampala, Uganda, I noticed so many place=village and place=neighbourhood , often the same name is duplicated.

MapSwipe on the Web Experience

Recently, I had the privilege of leading a MapSwipe training session for a corporate group, and it was an incredibly rewarding experience. While I’ve conducted online trainings before, this one felt particularly special. Despite my initial nerves, I was able to deliver a smooth and engaging training session.
Initially, I felt a bit nervous about taking on the role, especially since I was filling in for a colleague. “Corporate” to me also sounded really scary and extremely formal. However, with a bit of preparation and the support of a wonderful colleague, Nicole, I gained the confidence to deliver a successful training session. I focused on guiding participants through the web version of MapSwipe, a tool close to my heart.
Backround
About 6 years ago now, the Ireland OSM community had a bunch of online and face-to-face discussions. There was a desire to have a common campaign, rather than everyone just paddling their own canoe, mapping old boundaries, addding 110KV monster pylons, plotting the holy stones of Clonrickert, or whatever you are having yourself.
Why Buildings?
And so #osmIRL_buildings was born. It took lots of months to pull together. There was a discussion document put out, and lots of decisions and guidance via videos, long conversations on Telegram, and frequent issues discussed on the mailing lists. The task was designed with a few things in mind. Firstly, the community recognized that compared to other territories, we had relatively small levels of completion of buildings. Secondly, a prominent academic had stated that the Irish Government knew more about the number and condition of cattle than it did about buildings. Thirdly, a lot of citizen science projects were trying to collate and capture where derelict and disused buildings were located in cities, with the hope that they might be repurposed for housing. Fourthly, there was a National Planning Framework launched in 2018 that concluded that the spaces for the next 1 million people to live in could not be sprawl outside of Ireland’s cities and towns. There were other reasons too, but those are the ones I recall, so apologies to all those other reasons and their proponents. Nevertheless, all of the ones I mention here could have been addressed by the creation of a fully open spatial dataset of the buildings on the island, and not what passes for open data by data.gov.ie.
Reservations
Of course there were detractors; some mappers worried about the threat of being inundated by the glibness of millions of “building”=”yes” objects. One man in Kilkenny was worried that the climate would have changed by the time the task would finish. He might yet be right.
Kick Off
Had to write something about this. Well, the USA Geofabrik (Continental + HI and AK) extract is now well over 10GiB. And my poor Garmins still only can handle 4GiB gmapsupp.img files. Yeah, I have to lose over 6GiB of stuff now to get it to fit. I’m not sure how long this is tenable, but yes it’s a continuing struggle to get it to still work…

I am honored to have participated in the 2024 Climate Change Challenge as a member of “𝑻𝒉𝒆 𝑷𝒊𝒏 𝑫𝒓𝒐𝒑𝒑𝒆𝒓𝒔”. This challenge, organized by the Open Mapping Hub - Asia Pacific from May 20 to June 20, 2024, brought together over 200 participants from 54 teams to address climate change through collaborative open mapping efforts. I am grateful for the opportunity to contribute my mapping skills alongside so many passionate individuals, and I am proud to have received the Certificate of Participation. It’s inspiring to see how open mapping can make a real impact on global climate action.

The Discovery
Today was a big milestone for me as an OpenStreetMap (OSM) contributor—I submitted my first-ever bug report! 🎉
- While exploring the iD Editor, I stumbled upon something odd. When the “Quality Assurance” tab in the Help section is open, the “Keyboard Shortcuts” option becomes unclickable. Strange, right? What’s even more curious is that this doesn’t happen with any other Help tab—just this one. Naturally, I couldn’t let it go unnoticed.
The Process
Here’s what I did step-by-step:
-
I opened the Help section and navigated through different tabs to test the behavior.
-
As expected, all the other tabs worked fine, but when “Quality Assurance” was active, the “Keyboard Shortcuts” button refused to work.
-
To make sure my findings were clear, I documented:
- Steps to reproduce the issue.
- What I expected to happen versus what actually happened.
- Screenshots to visually explain the problem.
The Submission
Feeling a little nervous, I finally submitted my findings as Issue #10573 on GitHub. To my surprise, within hours, one of the repository maintainer (@tyrasd) confirmed the issue!
Here’s the coolest twist: The issue behaves differently in other languages! For example, it doesn’t happen in the Italian locale. This insight gave me a new appreciation for the complexity of building tools that work seamlessly across different environments.
The Reflection
This may seem like a small contribution, but to me, it feels huge. By reporting this bug, I’ve left my little mark on a platform I admire so much. It’s exciting to know that even small actions like this help improve the tools that people worldwide rely on every day.
The OSM community is incredibly welcoming, and this experience reminded me that even as a beginner, my efforts are valued.
Final Thoughts
Santarém To Belém - We Ran Out Of River
Daybreak on our last full day on the river could hardly have been more depressing. The sky I could see from my hammock was a grey-brown colour, and the smell of burning wood was stronger than ever. We were in the middle of the river and there was very little visibility. It hardly even makes It into the news headlines any more, our ability to adapt to the mess we have created means that relatively few people are aware of just how serious the situation is as Amazonía burns.
Fortunately we were not going to spend all of the last leg with the smog. Slowly the sky started to clear, and things seemed better again. The forest on either side even looked a bit more like It had in the upper part of the river.
About 2 days ago, the map started to be darkened. This only occurs on Firefox and Chrome, and it appears to be caused by the browser’s light/dark settings. I am still not certain about the cause.
