The State of the Map Call for Proposals deadline is approaching fast, and I know that feeling - staring at a blank page, wondering if your OSM experience is “conference-worthy.” Here’s the truth: if you’ve ever mapped something, solved a problem with OSM data, or helped someone learn about OpenStreetMap, you have a story worth sharing at State of the Map 2025!

What to Present On?

I think that often, the biggest hurdle isn’t writing the proposal - it’s deciding what to propose.

Talk About What You Know: Your OSM Journey

The best State of the Map talks come from personal experience. Think about:

• What tool or technique do you use that others might not know about?
• How has your mapping journey evolved?
• What do you know now that you wish you’d have known when starting?

Share What You Learned the Hard Way

Day 1) Home

忘れるかもしれないので備忘録として書き留めておく。

種別	編集ルール
一般道（2車線以上）	センターラインのある一般道。
一般道（2車線未満）	5.5m以上の一般道。見た目2車線分の広さがあるような道路。センターラインこそないものの、道路の中心を境に舗装が塗り分けられていたりする。通過交通に使われることも想定するので、5.5ｍ以上の道路に接続していない場合は住宅地区の道路に格下げする。
住宅地区の道路	5.5m未満3m以上の一般道。1.5車線、なんとか離合はできるかも。5.5ｍ以上の道路でも、5.5ｍ以上の道路に接続していない場合は住宅地区の道路として扱う。
路地	3m未満2m以上の道路。ぎりぎり1車線、対向車が来たら焦る。
敷地内道路（全般）	敷地（学校やGS等）の中の道路。団地内の道路も含む。
小道（自動車通行不可）	2ｍ未満の道路。明示的に車両通行禁止となっていないが、車は無理だろうという道路。
歩道	標識や車止めなどで明示的に車両通行禁止となっている道路。

幅員は 自治体の提供する幅員マップを参考にはするが、必ずしも正確ではないので、最終的には見た目で判断する。

We know OpenStreetMap is one of the most powerful and collaborative geospatial databases in the world. It relies on contributions from everyday users, developers, humanitarian workers, and mapping enthusiasts to keep data accurate and up to date.
But like any open data project, OSM faces issues. And understanding the types of issues we encounter is essential to maintaining map quality. One simple and effective way to think about OSM data problems is, to divide them into two broad categories:

1. Existing Issues: Errors in the Map

These are problems that exist within the current OSM data. The features are already mapped, but something about them is incorrect, inconsistent, or outdated.

Common examples:

• Incorrect tags: A residential road tagged as a motorway.
• Geometry errors: Buildings that are misaligned, roads that don’t connect properly, or rivers overlapping with buildings.
• Outdated features: A shop that closed years ago but still shows up on the map.
• Inconsistencies: Using different tags for the same type of feature in nearby areas (amenity=school vs. building=school).

2. Non-Existing Issues: Missing from the Map

These are features or data that should be on the map but are completely absent. The problem here is not about fixing what’s wrong, it’s about recognizing what’s not there at all.

Common examples:

• Unmapped buildings visible in satellite imagery.
• New roads or paths that haven’t been digitized.
• Missing POIs like schools, hospitals, or shops.
• Lack of metadata such as opening hours, accessibility info, or addresses.

In 2025, OpenStreetMap Taiwan Community has started to cooperate with Wikidata Taiwan Community to organize Street View Tour again, and in April, the tour was to Huwei and Tuku townships in Yunlin county. The funding source of this tour was Wikimedia Association of Taiwan, and the lunches for the two days (4/26 and 4/27) were sponsored by TomTom company.

The tour gathered outside the Yunlin High Speed Rail station in the morning of 4/26, and then set off to Huwei and Tuku townships to take photos of various temples related to Yunlin Liufang Mazu religion. Even though this was a street view tour, there were a lot of problems with the 360 camera this time 🫠, the one in the author’s car was always crashed (overheated?), while the one in the other car was never able to connect to the cell phone. The one on the car I was driving was always crashed (overheating?), while the one on the other car could not be connected by cell phone. Nonetheless, 53,854 street photos were uploaded to Mapillary this time (including both flat and 360 panoramic photos, some of which have not yet been uploaded at the time of writing this diary).

Pertanyaan mimin SGPC alias tukangsampat at the OpenStreetMap sederhana.

Banyak variasi jalan gang yang tergambar di peta OSM di Indonesia yang tidak seragam. Sebaiknya, untuk standarisasi sebaiknya, jalan gang di Indonesia:

• ditanda sebagai alley (highway:service, service:alley)
• ditandai sebagai jalan setapak untuk pejalan kaki (highway:footway) - yang artinya satu jenis tag dengan jalan setapak biasa
• atau sebagai jalan bersama (highway:living_street)

Cukup banyak gang di kota-kota maupun pedesaan di Tanah Air yang terasa terlalu lebar untuk sepeda motor namun sempit untuk kendaraan roda empat, tetapi dalam editor tag Allowed Access (motor_vehicle) bisa diartikan baik roda dua maupun roda empat, jadi sulit mencari pengecualian. Saat ini, versi mimin adalah merupakan sebuah alley.

Para que servem os dados do OpenStreetMap?

O OpenStreetMap (OSM) é um projeto colaborativo que tem como objetivo criar um mapa mundial livre e editável. Mas para além de um simples mapa, o verdadeiro poder do OSM está nos seus dados geográficos abertos, que são utilizados por milhares de pessoas, empresas e governos em todo o mundo. Mas afinal, para que servem os dados do OpenStreetMap? 1. Navegação e Mobilidade Urbana

Muitos aplicativos de GPS e navegação utilizam os dados do OSM para oferecer rotas, calcular distâncias e estimar tempos de viagem. Serviços como o OsmAnd, Maps.me e até partes do Mapbox e Uber usam esses dados. Além disso, o OSM é essencial para soluções de mobilidade urbana, como planejamento de ciclovias, linhas de ônibus e análise de acessibilidade. 2. Planejamento Urbano e Infraestrutura

Prefeituras, engenheiros e urbanistas utilizam os dados do OpenStreetMap para:

Mapear ruas, calçadas, escolas e hospitais;

Identificar áreas sem infraestrutura básica;

oh well, imgur doesn’t seem to work.

Прекрасно коли моя рідна громада була мною розмальована раніше. А ще приємніше коли ти малюєш сусідні громади. Сьогодні 7 травня 25 р. роботи по нанесенню на карту території Вовковинської громади завершені. Природні об’єкти громади картографовані на 100% (в т.ч. території населених пунктів, АЛЕ за винятком об’єктів всередині самих же населених пунктів, вони не враховані). Першими малювались об’єкти близ села Галузинці, останньою правкою було нанесення границь села Старий Майдан. Особлива увага була звернута на залізницю (некоректно було намальовано зупинні пункти), на траси (неточності геометрії) і на старі об’єкти які були намальовані колись іншими учасниками (актуальність була втрачена, на нових супутниках багато полів та лісів змінили свої границі).

І око милує, коли з електрички ти дивишся на не білу пусту текстуру, а на кожен нанесений об’єкт.

It was a beautiful day for a hike, so I set out early at 8am sharp. I headed back to Ely, trekked some of the trails in Plymouth Great Wood, cut through the park in St Fagans, passed through Western Cemetery, then over to the iron-age hillfort in Caerau. All was going to plan — until, that is, it wasn’t. While taking some snapshots at the hillfort, I fell and sprained my ankle.

I’ve no idea what happened – I was taking my time, walking along, and then I was flat on my face. I remember hearing a squeaking sound, the kind of sound a gym shoe makes on a squash court (so I either slipped on a root or a rock, or I killed something cute and fluffy).

So there I was , stuck in the middle of field with nothing to help me up. Great. And I somehow had to get back down a very steep hill. Brilliant. And then I had to get home. Jolly-well fantastic.

After, looking up at the sky for an hour, I managed to get to my feet. I couldn’t put weight on my over-turned ankle, so the trip back down took an age. With the aid of my trusty hiking pole, I finally got to a bus stop.

At least I got what I wanted to get — a clearer picture of the woodland trails and the layout of the roads in the cemetery (all in the name of improving Open Street Map). I also now have the perfect excuse for buying a new pair of trail boots.

Although the sprain is quite bad, nothing seems to be broken — the swelling is fairly minor, and I’m not in a great deal of pain. I won’t be strolling about for a while, but I’m hoping that the ‘while’ is a short one.

Hello all, to start with, I’ve always been interested in open software and collaborative projects. I actually made an OSM account way back in 2012, as you can see on the HDYC website. I can’t really remember why I made it to be honest. I may have found it via Wikipedia or something.

But it was three years ago today that I did my first changeset. I had yet to learn about all the mapping resources available to me, especially the GSImaps/pale layer from the Japanese government. This in combination with the JOSM areaselector plugin has been really useful for quickly mapping buildings in Japan. There are a lot of hiking trails on there too, and I can see now that I didn’t really need to use my GPX track to map the trail up to the Kamiyahagi Wind Farm and the observation deck up there way back in that first edit.

I’m grateful to this community for providing me with a useful hobby to do and that I have fun with. It perfectly compliments my outdoorsy walking and hiking lifestyle, my detail-focused mindset, as well as my tendency to hyper-focus (yay ADHD!) and being comfortable with sitting on JOSM and just meditatively mapping. It’s wonderfully calming. I greatly enjoy that I’m making an impact on the world through what I love to do.

I have been making an effort to direct people to OSM resources on r/BuyFromEU as much as I can, as there’s been an increased interest in switching away from US tech companies to services like Mapy and Magic Earth and I see it as a great opportunity for more people to join and improve the map. There are so many services that use OSM, but I think a lot of users aren’t even aware that the map can be edited or that improvements are welcome. I sometimes see references to “the official OSM app,” which is referencing OSMAnd. I think for some, the concept of it just being a database that the various apps get the data from can be hard to understand. But overall, I’m really glad to see more people get on board.

開放街圖臺灣社群2025年又閣開始佮 Wikidata 臺灣社群合作舉辦街景踏查團，這改4月份是到雲林縣的虎尾鎮佮土庫鎮踏查，踏查團的經費來源是對台灣維基媒體協會來的，兩工（4/26、4/27）的中晝頓由 TomTom 公司贊助。

這改踏查團佇4/26早起對雲林高鐵站外集合，隨就出發前往虎尾鎮佮土庫鎮和六房天上聖母信仰相關的廟宇拍攝照片，雖罔講是街景踏查團，毋過這改360相機問題袂少🫠，囥佇筆者所駕駛的車頂的這台是定定當機（傷熱？），另外一台車頂的是一直無法度予手機連使用。雖綱按呢，這改猶是有上傳 53,854 張街景照到 Mapillary（同時間包含平面相片片佮360環景照片，對筆者撰寫這篇日記的時，猶閣有部份的照片猶末上傳）。

Supaplex 講述 OpenStreetMap

第二工 (4/27) 是這改踏查團的編輯工作坊，佇本年度的六房天上聖母 紅壇舉辦，和本次踏查團相關的開放街圖編輯攏有 #tt_event 主題標籤（可能會當直接寫佇變更集的註記當中，或抑是寫佇變更集的 hashtags 標籤當中），欲看維基媒體計畫的編輯會當佇 [Dashboard] 中來檢視。

關於 OpenStreetMap 臺灣

OpenStreetMap 臺灣是由台灣關心投入 OpenStreetMap 的編輯者所組成，自從 2010 年開始由個孤一个人獨自編輯變成集結閣較濟人參與的共編地圖專案的在地社群。目前佇台灣有仃台北佮 Wikidata 社群共同舉行的 OpenStreetMap x Wikidata 月聚，閣有無定期的踏查活動。
