讨论在Telegram「OpenStreetMap China (OSM中国)」之「行政区划 Administration」主题发生，本日的群组讨论由平潭县和平潭综合试验区的标注处理引发，进而谈到了关于place标签在国内标注的讨论，主要包含下面内容：

下午十六时至晚上二十一时的讨论

• 「黑区」关系的标注：黑区是指非正式行政区划建制但是有行政管理机构的地域（行政管理区），通过讨论，群组内同意「几套牌子是几个relation，实际管辖用来区分是否作为subarea和subarea缀在谁下面」。以平潭县和平潭综合试验区为例，存在二者实体，故二者关系分开，但区域重叠；县归属福州市（在未明确县为试验区管辖时），试验区直属于福建省，故将县作为福州市的subarea，试验区作为省的subarea；省、市的界线均包含平潭。
• 街道、社区的节点标注（未达成共识）：现状街道在国内大量有标注，但与街道相近、同为政府派出机构的区公所不进行节点标注；街道、社区是否标注在不同地方情况不一致，群组对是否一定要标注二者未达成共识。支持者认为有很多街道、社区的名称可以代表地名，即使是不代表地名，其作为一个实际存在的行政实体也该标注；不支持者认为也有很多街道是「〇〇路街道」、社区是「{小区名}社区」，而地图已有该〇〇路道路或{小区名}小区（类型为way），但街道驻地可能与该路相距甚远（节点位置偏差过大），或与小区过于重合（重复标注），导致节点的标注反而不清晰。
• 行政区划和其他地名标注：群组同意在国内place标签之「city」「town」值现状已经与行政区划强相关，前者用于直辖市、地级、县级行政区，后者用于乡级行政区；群组同意不应该将「city」「town」仅绑定在行政区划（及黑区）上，无行政建制区域的地名（比如自然村、一些工业园区）也需要通过place=*表示，且在必要情况下也可以使用「city」或「town」（比如现状胶南，胶南市被撤销，但现状明显单独成城），不过应该控制此类标注的数目。有人提出有行政区划建制的应当先标注行政区划的节点，剩下的再按照place=*原定义标注，且不添加行政区划通名（自然村有争议）；此外，有人提出没有建制时应该先考虑是否有其他要素可以表示该地名，如有，则优先使用其他要素（详见下一条）；也有人提出town、city级别的非行政区可以使用place=suburb处理，不过同时被认为是滥用suburb（未形成共识）。

【编辑】晚上二十一时以将的讨论

• 有具体要素则不添加额外的地名节点：群组同意在一个具体要素较为知名，导致要素周边的区域也被统称这个要素的名称的情况下，当该要素仍然存在、指代该周边区域的地名与要素本名相同或等价、且该区域没有与该要素偏离过远，则不应额外添加地名节点。例如重庆解放碑是一座具体的纪念碑，重庆居民一般统称该碑及附近步行街街区为「解放碑」，在纪念碑被绘制的情况下，不额外添加带有place标签的「解放碑」节点；又如延吉火车站南部一片区域被称为「铁南」，明显为该火车站之南之意，但因为该地名比火车站多了「南」之意，可以标注。

Deutsche Post, which operates almost all of Germany’s postboxes, recently changed the collection times for most of them. This was discussed on the German Forum starting 4th of April. I wondered if this could be seen in the database.

So I created this diagram:

Recientemente se han añadido al mapa de Málaga los puntos singulares del terreno, diferenciando entre picos y collados. También se han añadido los datos de elevación sobre el nivel del mar de dichos puntos. Se ha tomado como fuente el Mapa Topográfico Nacional, disponible en el sitio web de OpenStreetMap. El Instituto Geográfico Nacional dio permiso hace años para la utilización de esta información y el propio Instituto está acreditado adecuadamente en la página de colaboradores de OSM. La diferencia entre un «natural=peak» y un «natural=hill» es muy controvertida en OSM, por lo que se ha optado por añadir los picos como «natural=peak» y los collados como «natural=saddle». Los datos se han revisado uno por uno.

“Tudo vale a pena, se a alma não é pequena”: minha carta de agradecimento

---

Prezados colegas,

Sou a Dra. Raquel Dezidério Souto, presidenta do Instituto Virtual para o Desenvolvimento Sustentável - IVIDES.org e pesquisadora em estágio pós-doutoral junto ao Programa de Pós-graduação em Geografia - PPGG-UFRJ. Gostaria de participar deste momento especial de comemoração dos 30 anos do Laboratório de Cartografia, GeoCart-UFRJ, com esta singela mensagem de agradecimento por toda contribuição na minha trajetória acadêmica e profissional, aos professores coordenadores, Dr. Paulo Menezes e Dr. Manoel Fernandes, e colegas de laboratório; gratidão estendida ao PPGG-UFRJ.

Ainda em 2012, eu ingressei no PPGG-UFRJ, como doutoranda do programa, tendo conseguido o primeiro lugar no processo seletivo de novos pesquisadores na linha “Planejamento e gestão ambiental”, com o projeto que teve foco na concepção de uma metodologia para geração de assinatura de sustentabilidade para os municípios costeiros do Rio de Janeiro, a partir de um sistema de indicadores de sustentabilidade. Naquela etapa da minha carreira, o apoio incondicional do Prof. Paulo Menezes foi fundamental, me levando a alcançar o meu título de doutora em ciências (geografia) em 2016. A tese está disponível no Portal Minerva da UFRJ.

Em 2019, eu regressei ao PPGG-UFRJ e ao GeoCart, como pós-doutoranda, também como primeira colocada no processo seletivo, com o projeto de pesquisa sobre a aplicação de mapeamento participativo para inferir sobre a qualidade ambiental na zona costeira (ZC) do estado do Rio de Janeiro. Consegui executar o projeto proposto e, atualmente, está disponível uma plataforma de mapeamento colaborativo da ZC do RJ, que adota formulários eletrônicos para a entrada de dados, construídos com KoboToolbox; além do OpenStreetMap e do uMap, para disponibilização dos dados e informações em um mapa interativo, acessível pela Internet. Esta iniciativa pode ser conhecida no portal do IVIDES.org.

Streetcars Rule

I’m trying to make a map of a streetcar line that I think ought to be built.

Little did I know when I first started my job in Antarctica that I’d become obsessed with editing OpenStreetMap during my empty hours at work. While I made an account back in 2019, that was simply to add a missing sidewalk from my mission in India that bothered me. Last month, I was playing around with some maps, seeing how different engines would interpret a cycle route I frequently took back home, and I noticed the trail was laid out with a bit of jank. I decided I had an account and the fix would be easy, so I went ahead and did it. I then saw the sidewalk options, and started playing with infilling the sidewalks around the route.

That was a mistake.

I have since spent hours adding sidewalks everywhere I’ve been. As I learned the tools and improved my methods, I started looking at other options. Street lamps, lowered curbs with tactile paving, and power poles were next. I started looking into other ways to contribute and installed Street Complete on my phone. I saw my office trailer wasn’t listed on the map at McMurdo, so I used OSMTracker for Android to map it out (Turns out, my phones GPS combined with the poor signal so far south makes things a bit more challenging). I then started using it to map all the infrastructure I could reach. I spent 2 hours on one of my few 2-day weekends down here out in -10F weather mapping out the power poles and lines connecting them.

Needless to say, this has become a bit of an obsession, but I suppose if I’m going to have that, I can at least use it to do some good in the world, no matter how small. Now if you’ll excuse me, I’ve got some suburban sprawl to map out. Those sidewalks aren’t going to add themselves!

Today, I had a good time at the national office and Mapathon center of Unique Mappers Network-the OpenStreetMap Nigeria Community NGO (osm.org/#map=18/4.899962/6.921081) to engage newbies, signing them up and training them on how to contribute to OpenStreetMap. Among them are Ngozi,Fortune,David and Chika (NMak,verified,Peter Msiion D and Victoria Jaja). Please, check out for them to welcome them and share your success stories and motivation for OSM volunteering. Fortune(verifiedfortune) joining Unique Mappers IT cohort 1 for 2025 would be contributing for the next 6 months as part of his IT task. https://www.linkedin.com/feed/update/urn:li:activity:7329531711480926209 ![ ]

On 3rd May, We got back to our Map Nigeria Monthly Mapathon to sustain active OSM community participation in Nigeria, especially as we have mapping projects being coordinated in collaboration with TomTom one of Unique Mappers Network partner https://tasks.openstreetmap.us/projects/815#coordination . Volunteers joined from across the states and universities in Nigeria in a virtual coordinated mapathon, especially, the Unique Mappers Team we recently established in Abuja,Kaduna.Ile-Ife and Enugu.

In the first quarter of 2025, we have mobilized,signed-up and trained more than 100 newbies coordinated in a new whatsaap group of the community whatsaap group for orientation purposes. However, mapping contributions has been quite slow as the recent high increase in internet data subscription in Nigeria makes it more difficult for both old and new OSM volunteers to sacrifice the high cost of internet for voluntary mapping in OSM. You can hardly find free internet broad band access to engage volunteers in Mapathon.

Today 12th May 2025, I got to the place i’m suppose to do my IT, [INDUSTRIAL TRAINING], As at 10am in the morning when asked to come. I met 2 other people David and Ngozi, they welcomed me while i waited for the National Coordinator DR VICTOR .N. SUNDAY of unique mapper. After was, the National Coordinator DR Victor sunday came in, with out wasting much time, another person enter named chika i guess so, so he introduced OpenStreetMap to all of us that were there together. He said a lot of things about the OpenStreetMap, As what we use in carrying out mapping and it’s also free, like a volunteer thing. It was exciting to have DR Victor Sunday, the coordinator teach and talk about the OpenStreetMap, Me been introduce to OpenStreetMap, its not my first time but i was able to get a clear picture of what an OpenStreetMap was all about, which it was intresting, Now i can say i know how to map a building. yoooo!!! With everything that went on, everyone had to practice for themselves on learning how to do the mapping there self, which was cool and right now we are done with the classes on mapping as at 1:56PM, Everyone is expected to sign up with OpenStreetMap and map out at least 10 buildings showing you have learnt something for the day, hmmm its really a lot today though, i’m happy to have come here today and i’m ready for it. This is my passion, This is my dream,for the next six [6] months i will be here, i hope to achieve a lot, and thats it.

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
