RETEX : Les choix de tag pour mon trekking urbain recyclage

Hésitations, discussions, collisions avec d’autres contributeurs, changements, hésitations, … mais convergence.

à suivre peut-être :

• entrée de journal (à venir) : Questions existentielles sur ma rencontre avec panoramax

Au départ, taguer l’opérateur puisque c’est la cible du trekking.

L’opérateur est connu ici sous le nom GPSEO, ou GPS&O, ou Grand Paris Seine et/& Oise …. . Quel nom retenir ?
De même, j’ai rencontré des conteneurs à vêtements du Relais ou de Emmaüs et, là encore, quels noms retenir ?

ma rencontre avec wikidata

Grâce au forum, j’ai sur ce sujet été orienté vers wikidata qui permet d’affecter un code unique à un grand nombre de ressources (sociétés, opérateurs, communes, groupements, personnage à portée large, …).

Une fois la ressource concernée dotée d’un code wikidata, son entrée wikidata contient les données importantes (nom, site web, référence wikipedia, chiffre d’affaires, … ) et permet ainsi à toutes les applications de la sphère collaborative wikipedia d’accéder de façon commune à ces éléments. Il suffit donc de référencer le code wikidata de l’opérateur dans les étiquettes OSM pour identifier celui-ci de façon unique et stable. A partir de ce code, il sera aisé de retrouver le site WEB de l’opérateur, sa référence wikipedia et autres renseignements utiles sans avoir à les mettre comme étiquettes explicites de OSM (ce qui obligerait à mettre à jour OSM chaque fois que ces données changent).

Une seule concession nécessaire, me semble-t-il : j’ai récupéré le nom officiel de l’opérateur dans ses données wikidata et l’ai mis en étiquette OSM pour plus de lisibilité.

Et donc :

étiquettes omises volontairement car les informations sont évolutives et peuvent être trouvées dans l’article wikidata de l’opérateur :

Greetings whoever is reading this, including my future self who may be the only audience.

I was invited earlier this year to take part in an exhibit called [“Compass Roses”] (https://www.compassroses.art/), which will be on view at Opalka Gallery in Albany, NY this Fall.

“Compass Roses: Maps by Artists is a national artwork co-curated by Nadine Wasserman and Renee Piechocki. The project offers a selection of maps created by visual, literary, and performing artists. “

I chose to make a map of Gun Violence Memorials in Albany. I was inspired by a memorial called Chyna’s World, a mural in memory of an 18-year old high school senior named Chyna Forney. Chyna was killed in crossfire in an incident when her boyfriend fired over 30 rounds at another man. The mural is painted at the location where the incident took place. After seeing this mural, I wondered if there were others like it.

I have been aware of the problem of gun violence for this entire century. I have perceived it from three aspects that touch but are distinct: school shootings, the eclipse of streetfighting, and police murder. I might say more about those three in this diary over the next few months, but for now I will just say that these have been buried the past five years by the sheer numbers of tragic gun deaths in this country, in my city, in my neighborhood, on my street. There were 10 shootings on my street when the world broke down during New York Pause, from April 27 2020 a few weeks into the pandemic through December 19, 2021. The nadir was the late night murder of 15-year old Destiny Greene, on a magical little street called Wilbur. I remembered the temporary monument that Destiny’s family had set up on Wilbur Street, and the attempts by some neighbors to set up a permanent memorial for shooting victims.

Vector Tile styles require icons are served in a sprite sheet. This contains all of the icons in one file. Years ago there were a few options for these, none of them great. These days, there are three common options: spreet, https://www.openstreetmap.org/user/basemaps/sprites, and sprite-one. The first is written in Rust while the other two are written in Javascript.

All have the same basic functionality of turning a folder of SVGs into a json+png spritesheet, and doing so at multiple resolutions. Spreet has the additional option of de-duplicating icons. If two icons are identical it will only put one copy in the PNG and reference the same image twice.

I benchmarked all three options with two sets of sprites: all the SVGs from OpenStreetMap Carto, and the OpenStreetMap Americana icons. The former is 973 icons and the latter is 248 icons. These are larger than a typical set of icons but are a good test.

Et puis il y a les sites d’escalade, certains sites sont jolis , et d’autres moins, et n’ont peut être que d’intérêts pour les grimpeurs. :

• Site d’escalade des Chavants
• Site de la Plaine St Jean
• Site de La Duchère
• Les dalles de l’Arveyron par contre la voie caline n’est pas du tout là, c’est de l’autre côté du torrent, encore que l’itinéraire le plus proche est la via corda des chamois.

• Un peu de fraicheur mais en vrai, faut pas aller dans le lit du torrent , sans avoir relevé les dates affichées pas le Barrage d’Emosson.

I’m importing boundaries in Croatia, and I’m almost done. So I wanted to describe my process so that someone else maybe doesn’t have to rediscover this process. Maybe there is a better one, but I didn’t find it.

Croatia in OpenStreetMap had admin_level=7 borders imported, but the borders were not precise. So my job was to import admin_level=8 into these. I had the data in .osm format, and a license that is compatible. I wanted to keep the history of the old boundaries, so deleting everything and just copying inside wasn’t a choice.

First we need JOSM, and some experience with it. We turn on the Expert Mode in View. We need to install the plugin “utilsplugin2”. Then we go to Map Paint Styles in Preferences, and turn on the “Admin Boundaries” style.

So the process goes like this. In JOSM I open the .osm file with all the admin_level=8 boundaries. Then I download the area where I intend to work, but I use “Download from Overpass API” feature. In it I add the next Overpass query:

[out:xml][timeout:90][bbox:{{bbox}}];
(
relation["boundary"="administrative"];
)-> .adminrelations;
(  .adminrelations;
  way(r);
) -> .ways;
(
  node(w.ways);
)-> .nodes;

way(bn.nodes);
(._;<;); (._;>;);
out meta;

What this query does is it downloads all the boundary relations, and all the ways that are connected to them.

1. Disconnecting

Next step I did was to disconnect all the roads, forests, rivers and anything that is not a boundary from the existing boundaries. I upload that, and later download a cleaner situation.

2. Splitting

When using OSM’s iD editor in New South Wales, Australia, there are multiple background layers you can enable that show aerial/satellite imagery. Different imagery sources can vary greatly in terms of how recent and/or blurry they are. Here I’ll discuss my experience using them.

DCS NSW Imagery

This is my preferred imagery source, primarily because it’s very clear even at high zoom levels. You can see lots of detail which makes it great for mapping.

Unfortunately it’s also the oldest of the imagery sources for NSW. In Armidale it’s dated 2018, but other towns can be as old as 2009! You can enable the “DCS NSW Imagery Dates” overlay to see what date the imagery for a given area was taken.

Depois de mais de uma década contribuindo para o OpenStreetMap (OSM), finalmente decidi criar este blog. Quero compartilhar minhas experiências e mostrar o porquê de eu me dedicar tanto à melhoria do mapa. Acredito que esta seja uma maneira interessante de as pessoas entenderem o valor do mapeamento voluntário e a importância de ter um mapa preciso e detalhado, feito por pessoas para pessoas.

Minha jornada de mapeamento pelo Brasil Minha jornada começou melhorando o mapeamento do Espírito Santo, meu estado de residência, que conheço muito bem. Com o tempo, meu trabalho se expandiu para outras regiões que tive a oportunidade de conhecer, seja por viagens a trabalho, cicloviagens ou em passeios com a família.

Hoje, minhas contribuições se espalham por várias regiões do país:

Rio de Janeiro: Norte e Noroeste Fluminense.

Bahia: Extremo Sul, Sertão do São Francisco, Sisal e Itaparica.

Sergipe.

Minas Gerais: Cidades da Rota Imperial, Caminho dos Diamantes e Estrada Real, além dos Vales do Rio Pardo, Jequitinhonha e Mucuri.

Mapeamento: uma resposta à falta de informação

Durante minhas viagens, sempre percebi a ausência de informações importantes nos aplicativos que utilizo para me locomover, praticar esportes e fazer turismo. Essa falta de dados me inspirou a contribuir ativamente, pois notei que o mapeamento voluntário não é apenas um hobby, mas uma necessidade para preencher essas lacunas e tornar o mundo digital um reflexo mais fiel da realidade.

Projeto atual: Mapeando o Território de Identidade de Itaparica, na Bahia Atualmente, estou focado em mapear Macururé, um dos municípios que compõem o Território de Identidade de Itaparica, na Bahia. Os outros municípios do projeto são Paulo Afonso, Abaré, Chorrochó, Glória e Rodelas.

Hello, I would like to ask if in your country there are officially designated areas designated by local authorities (such as municipalities, civil protection agencies, emergency services, etc.) for:

Short-term population management (assembly points, waiting areas, temporary gathering places after an event). Long-term population management (tent camps, temporary housing sites, large shelters). Management of external rescue operations in response to the call (logistics bases, areas dedicated to external rescuers arriving from elsewhere, equipment sorting areas). These areas would be part of civil protection / emergency management planning, mapped and designated in advance, not improvised during the event.

Do such areas exist in your country? And if so, are they publicly available (e.g., through official maps, open data, local plans)?

Thanks in advance for your feedback!

OpenStreetMap (OSM) adalah basis data spasial yang Open Source. Data data pada OSM merupakan hasil dari kolaborasi dan kontribusi terbuka oleh kontributor dari komunitas sukarelawan. Namun mendengar kata kontribusi data untuk OSM, mungkin membuat sebagian besar masyarakat membayangkan proses yang sangat rumit, mulai dari harus menggunakan laptop, citra satelit, dan lain lain. Tapi ada loh cara yang yang sederhana untuk memberikan kontribusi, bahkan terasa seperti bermain game di smartphone. Caranya adalah dengan menggunakan aplikasi StreetComplete.

StreetComplete merupakan aplikasi yang memudahkan siapa saja untuk berkontribusi ke OSM tanpa harus jadi “ahli pemetaan” dulu. Alih-alih harus menggambar peta dari nol, aplikasi ini menyajikan misi-misi kecil berupa pertanyaan tentang lingkungan sekitar. Misalnya:

• Apakah jalan ini memiliki trotoar?
• Apa jam buka warung ini?
• Apakah bangunan ini punya atap datar atau miring?

Tugas-tugas kecil tersebut muncul dalam bentuk ikon di peta, dan pengguna cukup berjalan di sekitar lingkungan lalu menjawab pertanyaan dengan pilihan sederhana. Setiap kali kita menyelesaikan satu misi, terasa seperti menuntaskan quest dalam sebuah game.

Selain itu, StreetComplete memiliki sistem progress yang membuat pengguna merasa terus berkembang. Setiap kontribusi kita akan langsung memperkaya data di OpenStreetMap, sehingga manfaatnya nyata: data transportasi lebih lengkap, informasi fasilitas publik lebih akurat, dan peta menjadi lebih berguna untuk semua orang.

Hal menarik lainnya, kontribusi melalui StreetComplete bisa dilakukan sambil beraktivitas sehari-hari. Misalnya ketika jalan sore, berangkat kuliah, atau sekadar mampir ke warung. Jadi, tanpa terasa kita bisa membantu membangun peta dunia yang lebih baik hanya dengan "main game".

Sudah setahun saya berkontribusi dalam UPIYouthMapper. Saya juga ikut merayakan ulang tahun OpenStreetMap ke 20 di UPI dan ulang tahun OpenStreetMap ke 21 bersama POI, KAART, TOMTOM dan teman-teman UPIYouthMapper chapter ke 3.

Jika dibandingkan dengan kehidupan akademik atau himpunan mahasiswa, YouthMappers dan OpenStreetMap berbeda 180 derajat. Ketika saya dituntut untuk melaksanakan tugas saya di akademik atau hima, saya dituntun untuk berkontribusi pada YouthMappers dan OpenStreetMap.

Tidak ada paksaan, tidak ada sanksi. Saya bisa saja pergi dan tidak memberikan konrtibusi. Tapi tuntunan itu membuat saya lebih nyaman.

Saya bisa melakukannya sesuka hati saya, sekosong waktu saya. Namun efeknya luar biasa.

Sebagai mahasiswa yang sangat dengan dunia geospasial, OpenStreetMap menjadi salah satu sumber data untuk penelitian. Dan saya dapat berkontribusi kapan saja, lewat apa saja.

Jika sempat, saya dapat membuka laptop saya dan mengunjungi maproulette kemudian mengikuti challenge yang diberikan. Saya kira hal ini tidak bisa lebih mudah lagi.

Tapi pada perayaan ulang tahun ke 21 OpenStreetMap, saya mengenal banyak aplikasi. dan menurut saya yang paling nyaman digunakan adalah StreetComplete.

Rasanya hidup dalam dunia game dan memiliki sidequest yang sudah dibuat. Sehingga perjalanan kita pun memiliki kontribusi ke OpenStreetMap dan tidak perlu repot-repot untuk membuka laptop.

Saya sangat bersyukur bergabung dengan UPIYouthMapper, dari sini saya mengenal banyak orang-orang luarbiasa dan menjadi lebih dekat dengan dunia open data.

Karena kini informasi sekecil apapun dapat kita sumbangkan lewat ujung jari. lewat StreetComplete

I had the privilege of presenting about weeklyOSM at COSCUP 2025, Taiwan’s largest open source conference, held on August 9–10, 2025, at the National Taiwan University of Science and Technology (NTUST) in Taipei. This year also marked COSCUP’s 20th anniversary, making it an especially meaningful event to join in celebrating open source.

About My Presentation

My talk, titled “Behind the Scenes of weeklyOSM: How We Share OSM News Every Week,” focused on the inner workings of our community-driven newsletter.

For those unfamiliar, weeklyOSM is an independent, multilingual publication that has summarized developments in the OpenStreetMap (OSM) world every week for more than a decade—now surpassing 780 editions.

Key Topics

During the session, I highlighted:

• weeklyOSM’s Mission – Connecting mappers worldwide by bringing local stories to a global audience. We aim to be the heartbeat of the OSM community, delivering the pulse of mapping activities around the globe.
• Independence – weeklyOSM operates as an independent media platform, unaffiliated with any organization (including OSMF), and delivers news in over 15 languages to ensure accessibility for everyone.
• Our Toolchain – A closer look at OSMBC (OpenStreetMap Blog Collector), the open-source platform we use for collecting, authoring, translating, reviewing, and publishing news.
• How We Collect News – From OSM diaries, community channels, and social media, to direct submissions, ensuring comprehensive and balanced coverage.
• Taiwan’s Role – Taiwan’s active mapping scene and unique events, such as night market mapping parties, which exemplify how local stories can inspire and educate a global audience.

Why COSCUP Was the Right Place

Background

I’ve mapped in OSM for many years now, but more of my work and been Bike-Pedestrian related, and I’ve only just come back around to mapping streets their widths and their number of lanes as a means to start evaluating crossings in our area. This means, despite my many years of mapping, I’m pretty terrible at getting the number of lanes forward/backward/both_ways and the corresponding turns associated with them correct. It’s just not that intuitive, although I can’t think of a better option.

My solution

A while back I discovered the JOSM ‘map paint styles’ specifically the lanes and enhances lane styles and combined with some tagging presets I’ve gotten acceptable at mapping major roads and the ability to visualize if I’m doing things right is a huge benefit.

The 12m (39’) of road that once visualized, haunts me.

Berdampak dari Jauh: Kontribusi OSM sebagai Dampak dari Manusia, untuk Manusia

Memori Bencana Intragenerasi: Kebimbangan dan Ketidakberdayaan diri untuk Berdampak

Masih jelas teringat di kepala saya banyak sekali bencana alam yang terjadi, yang saya tonton dengan jelas setidak-tidaknya sejak masa kecil di siaran televisi. Tsunami mentawai 2010, tsunami besar di Jepang 2011, fenomena megathrust Palu 2018, hingga banjir besar di Demak pada 2023 lalu yang saya baca dengan jelas di laman berita hingga sosial media pada saat itu. Sebagai negara kepulauan, sudah menjadi pengetahuan umum yang diserap bahwa Indonesia merupakan negara yang rentan mengalami banyak sekali bencana tektonis dan hidrometeorologis. Belakangan, banyak kalangan menyebut Indonesia sebagai negara "laboratorium kebencanaan" karena sering dan beragamnya bencana alam yang terjadi.

5 anni fa ho iniziato a mappare su osm e devo dire che non ho mai avuto problemi con la mia community italiana, sopratutto perché le opinioni si esprimono in maniera dettagliata e cordiale, nonostante possano essere diverse.

Da quando ho scoperto che ci fossero linee guida consigliate nella wiki per gestire le bbox, ho cercato di ricordarlo a tutti gli utenti (alle prime armi o esperienziati) per semplificare le operazioni di noi locals nella verifica delle modifiche.

Purtroppo ho incontrato utenti non italiani che hanno espresso, attraverso ogni mezzo, il loro disappunto con prese in giro, umiliazioni e tutto ciò che ha a che fare con il bullismo.

Questa differenza tra la community italiana (dove si ragiona con serietà) e la parte rumorosa della communitiy internazionale (dove si risponde a suon di provocazioni) mi ha colpito a fondo rendendomi triste e ferito.

A questo punto mi sono chiesto se abbia veramente senso proseguire a migliorare la mappatura del territorio in cui vivo se sono circondato da utenti che non mi rispettano…

La risposta è sì, perché OpenStreetMap è un sistema open, bisognoso di dati e che ha bisogno di persone che cercano di fare il loro meglio, aiutando anche gli utenti “giovani” perché più siamo a mantenere un clima sano, più sano sarà il clima e coloro che rovinano il clima saranno sempre meno.

Dal punto di vista di gestire gli insulti e prese in giro che mi sono state recapitate mi sono già mosso come possibile, anche se l’operazione più efficace è stata quella di bloccare in tutti i social conosciuti, ove possibile, le persone che mi hanno schernito pubblicamente e privatamente.

Five years ago, I started mapping on OpenStreetMap, and I have to say that I have never had problems with my Italian community, especially because opinions are expressed in a detailed and cordial manner, even when they differ.

Since I discovered that there were recommended guidelines in the wiki for managing bounding boxes, I have tried to remind all users—whether beginners or experienced—about them, to make it easier for us locals to verify edits.

Unfortunately, I have encountered non-Italian users who have expressed their disapproval through teasing, humiliation, and everything associated with bullying.

This contrast between the Italian community (where people reason seriously) and the noisy part of the international community (where responses come in the form of provocations) has struck me deeply, leaving me sad and hurt.

At this point, I asked myself whether it really makes sense to continue improving the mapping of the territory where I live if I am surrounded by users who do not respect me…

The answer is yes, because OpenStreetMap is an open system, in need of data and people who try to do their best, also helping “younger” users. The more of us maintain a healthy environment, the healthier the community becomes, and the fewer those who ruin it will be.

Regarding the insults and teasing I have received, I have already taken all possible actions. The most effective measure has been to block, wherever possible, on all known social platforms the people who publicly and privately mocked me.
