Working mainly in Africa it’s not rare to come across to crowdsourced powered mapped areas. I still repair, from time to time, the disaster done in 2022 in Mogadishu

Today, near Bor osm.org/#map=17/6.178444/31.578194 , another masterpiece: a lot of triangular (one 2600 sqm trapezoidal) buildings, and 3 tourism=camp_site

Who does need this rubbish? How good the validator to the related HOT task worked?

I really wanted to participate in the State of the Map 2024 in Kenya to broaden my horizons, understand what is happening under other skies and exchange with members of other communities to draw from their experience: How they are organized and how they stay dynamic. My illusions found a dazzling light, from the moment the scholarship team accepted my application. I was so happy like my wedding day. 😃

The 3 days were each particularly better, the different subjects selected were breathtaking

Contexto

---

O estado do Rio Grande do Sul (Brasil) foi acometido por um dos maiores desastres socioambientais do Brasil, com 173 mortes, 478 municípios atingidos (do total de 497) e cerca de 2,3 milhões de pessoas afetadas, segundo os dados da Defesa Civil do Estado [1].

No entanto, a importância dos dados abertos e dos programas livres ainda não está clara para muitos gestores públicos e outros atores, o que leva à ineficácia das ações e das políticas de prevenção e mitigação dos danos causados por desastres. O Instituto Virtual para o Desenvolvimento Sustentável - IVIDES.org tem realizado ações abertas ao público, há alguns anos, no sentido de contribuir para o aumento da conscientização a respeito das oportunidades proporcionadas pelo software livre e pelos dados abertos, em diferentes contextos. Nessa via, o IVIDES.org tem atuado também na formação de novos(as) mapeadores(as) do OpenStreetMap, mantendo um curso de capacitação on-line e completo, disponível em https://curso-osm.ivides.org, com emissão de certificados, duas vezes ao ano.

Punt 1

Кто-нибудь умеет в нейронные сетки?

Кажется, технологии созрели в достаточной степени для того, чтобы генерить нейросетками хотя бы двумерные изображения зданий по словесным описаниям, сделанными из тегов.

Я попробовал Кадинского. Рисует он неплохо, но архитектурная терминология для него ничего не значит, и в добавок он считать не умеет.

Промт: “Здание железнодорожного вокзала в псевдорусском стиле четыре этажа, акварель.”

Неплохо. И правда напоминает провинциальный вокзал, но искусственный мозг не понимает, что у здания должен быть вход. (А у вокзала еще и обязательно с двух сторон, хе-хе.) Требование про четыре этажа проигнорировано.

Промт: Белая шатровая церковь в стиле нарышкинское барокко, с пятью куполами, акварель.

I am happy to receive the HOT Open Summit scholarship to attend the State of the Map 2024 held in Kenya. I can give a lecture on-site. But unfortunately, I got influenza and felt very ill during my trip to Kenya. Most of the time I have to stay in bed. So sad I can’t join the meeting during the conference.

I had to skip the first day of the conference in the first day due to illness. But I feel better the second day. The conference was held in the hall in Nairobi Tower, University of Nairobi, which is quite comfortable for all of us attendees. This is my third State of the Map, the second time in person.

It seems that the conference was held in Africa and quite a distance from most of the OpenStreetMap contributors. There is a much smaller size compared to other years’ State of the Map conference. It is still a very valuable experience. Face-to-face communication is still the most effective way to communicate between OpenStreetMap contributors.

真歡喜得到HOT Open Summit的補助金參與這改佇肯亞舉行的State of the Map 2024，會當去現場發表我的演講主題。毋過真可惜去的時陣破病，倒佇眠床休養，無法度有真濟佮參與者的互動。

(圖片：Arnalie翕相)

大會第一工倒佇眠床規工，第二工才有法度去會場。佇大學內底的高塔建築Nairubi Tower的會議中心舉行，算是真四序的場地。這是我第三改參與State of the Map，第二改現場參與。可能因為去非洲的路途較遠，整體規模較細，毋過會當面對面交關是真寶貴的體驗。家己有拄著一个編輯器開發者，伊共我講伊熟似yellowsoer，佮伊反應Go Map!!的問題。𪜶太太是台灣人，所以一直佮𪜶翁仔某開講。𪜶講欲來台灣一逝，到時欲來聚會。

我家己的演講部份，分享地址匯入工課，順紲講台灣社群最近咧無閒啥。有人回應問以後資料更新的部份按怎進行，我老實講有拄著閣討論，若是有發現問題就修正，照OpenStreetMap的規則進行。

Ce week-end, j’ai été impressionné par la qualité du routage de brouter. Un trajet de 150km sans soucis, j’ai été impressionné.

Je me met donc aujourd’hui à étendre un peu la richesse d’OSM dans mon petit coin de pays.

Merci à toustes

With my State of the Map Working Group - communications hat 👒 , one thing that really put a smile on my face is checking the stats of scholarships given! 😍

Quick stats re scholars from the OSMF SotM WG & Humanitarian OpenStreetMap Team #HOTOpenSummit Travel Grant Programs:

• 💻 10 online scholars
• ✈ 50 in-person scholars
• 🌍 🌎 🌏 from 27 countries
• 💛 💜 24 women : 36 men
• 1️⃣ 80% attended their first #StateoftheMap conference!
• plus 29 🎟 were given for free!

I cannot express enough how amazing it feels to see this stats. As someone who got exposed more to OpenStreetMap community after attending her first global SotM conference six years ago (my diary here), this gave me much hope and encouragement that we’re building an inclusive map and community 🗺 🤝

Seit kurzem dabei….

Uli, 61 Jahre aus Gladbeck. Seit Juni 2024 bin ich Mapper und versuche mich in OSM einzuarbeiten indem ich meinen Heimatstadtteil Buttendorf mal genauer betrachte und Fehler berichtige.

Ich freue mich über Kontakte in Gladbeck und natürlich über Hinweise wenn ich mal was falsch editiere.

Bis bald

Uli

Come closer and let’s have a quick, impactful conversation…

Hear me out. As a student, there are countless opportunities you can tap into, especially when it comes to personal and professional growth and one of the best social clubs to join is YouthMappers.

Imagine being part of a global movement where university students like you are trained free of charge to use powerful mobile mapping apps and software, contributing directly to sustainable development. It’s not just about learning new skills—it’s about making our communities visible, especially those that are too often overlooked. But wait, here’s the real question: How committed, dedicated, and ready are you to volunteer and contribute to OpenStreetMap? 🤔 It’s more than mapping—it’s about creating change, ensuring no place is left behind, and bringing solutions to real-world problems.

Giving back to the community has been the focus. On 26_07_24, I had the opportunity to meet the UMaT YouthMappers chapter while attending the 5th WAIMM Students Conference (an annual 3-day conference). I introduced YouthMappers, the basics of JOSM, and OpenStreetMap, especially to the chapter’s ‘youngies’, and explained who we are and what we do. I also shared some success stories to vindicate the benefits of YM, such as broadening interpersonal geospatial knowledge, connecting and networking with like-minded individuals, and belonging to a community of youth who are mappers. We swiftly discussed Mapillary and how it complements JOSM data validation, and also what it takes for a chapter to be sustainable.

On March 15th and 16th, OpenStreetMap Ghana (Sir Mawutor) and I visited UCC YouthMappers to familiarize them with how to fly a drone to map and to also map with Mapillary. It turned out to be an excellent result—a massive turnout. Appreciation to Dr. Julia (the Patron) and Dr. Mensah (the GIS lecturer) for creating an enabling environment for the Chapter and to the vibrant TEAM for rendering voluntary service to the membership. This is far-reaching. 🗺️🤌🏾

I am grateful to YouthMappers for providing me with the knowledge and abilities that would enable me to impact and transform deprived communities and contribute to sustainable development. 52 students, 26 countries, and 49 academic institutions—it was incredible to meet these young future leaders who are enthusiastic, passionate, and have the zeal for change through this inspiring leadership summit in Jamaica.

Big thanks to everyone who helped make the summit a success, including the speakers, navigators, photographers, and event planners. I have learned a lot in addition to mapping by learning about the traditions of my fellow nations and dispelling certain misconceptions about Jamaica, the host nation.

I would again like to thank YouthMappers for giving me international exposure. This built my confidence as a change-ready youth leader. I appreciate the recognition.

放送大学の「地理空間情報の活用」第１回番組内で紹介されていました。 自分の生活圏内と出かけ先の地図を盛り立てていきたいです。 アップロード方法？などもわかりませんが…。

Once upon a time a bunch of people decided to start collecting informative bits about stuff they‘re concerned with into a geo-referenced database. They mapped streets – hence the name of their experiment – and also PoIs. Records consist of a so-called tags, key-value pairs. In hindsight tags are differentiated into a primary tag, a.k.a. the substance/essence and a number of secondary tags, a.k.a. the attributes. There‘d be e.g. highway=secondary; name=Abbey Road.

One of those days, somebody noticed a problem: They wanted to map a so-called shared-space, where pedal cycles and pedestrians both allowed and traffic sings put up to show that intention. One solution might have been to tag a highway=cycleway;footway. Thereby turning the right hand side of the tag into a list. This looked ugly, a tag no longer would code for a 1:1 relation but a 1:n relation. Users of the data do not like that.

Some pondering later, the idea was born: Put the function/use/arbitrary detail of the mapped entity into the attributes where they can merrily coexist. foot=designated; bicycle=designated should from now on convey what previously was told by the primary tag. Only problem left: What would be the substance then? It must be something generic, something that provides as little information as possible over what the highway key already contains.

This marked the inception of highway=path as a light and unspecific shim over highway. All it says: It is probably narrow (But don‘t depend on that.) You likely will not see cars moving there. (With few exceptions.)

So they married, and everyone lived happily ever after.

I’d like to announce the release of the new major version 4 of pyosmium.

pyosmium was originally created as a thin Python wrapper around the osmium library, a fast and flexible C++ library for reading, writing and processing OSM data. With the new version 4, pyosmium adds a convenience layer on top which gives the library a more pythonic feel and speeds up processing considerably.

The most important new features are:

• Iterative processing. OSM files can now be iterated through with an simple for loop. (Processing a file using handler functions is still possible.)
• Filter functions allow to quickly skip over uninteresting parts of the file, making it now possible to use pyosmium scripts with large OSM files without pre-filtering.
• Writers with automatic reference completion. One of the challenges of writing OSM files is that for every way and relation written, you usually also need to write the nodes and members. pyosmium now implements writers which help with that.

Here is an example how to quickly find the most frequent tags used together with amenity=school using the new iterative syntax:

import osmium
from collections import Counter

tag_counter = Counter()
total = 0

for o in osmium.FileProcessor('planet.osm.pbf')\
               .with_filter(osmium.filter.TagFilter(('amenity', 'school'))):
    tag_counter.update([tag.k for tag in o.tags if tag.k != 'amenity'])
    total += 1

for tag, cnt in tag_counter.most_common(10):
    print(f"{cnt:6d} ({cnt*100/total:5.2f}%) {tag}")

Running this on a full OSM planet file takes less than 5 minutes on a 12-core machine with 128GB RAM.

Or do you want to create an thematic extract of schools:

import osmium

with osmium.BackReferenceWriter('schools.pbf', 'planet.osm.pbf',
                                overwrite=True) as writer:
    for o in osmium.FileProcessor('planet.osm.pbf')\
                   .with_filter(osmium.filter.TagFilter(('amenity', 'school'))):
        writer.add(o)
