Ich meine das Dorf Himmelreich in der Gemeinde Raaba-Grambach :-)

Das Hinterland der Industriezentren Raaba und Grambach ist überraschend ruhig und eignet sich hervorragend für Radtouren. Bei einer dieser Touren bemerkte ich den großen Unterschied zwischen der Lage nach Ortstafeln und den geographischen Punkt Himmelreich in der OSM-Karte.

Quelle war das Bundesamt für Eich- und Vermessungswesen (BEV), die das Dorf Himmelreich auf die Höhe von Berndorf verortet, wohingegen alle Ortstafeln deutlich nördlicher liegen:

Mapeamento de Trilhas do MUSA

Hello everyone, I am here again with the last Blog of my journey as an Outreachy intern. For those who don’t know me , I am Neelima Mohanty , selected as an Outreachy intern at Humanitarian OpenStreetMap Team (HOTOSM) for the May to August Cohort. If you are new to my blog then make sure you read my previous Outreachy Blogs before going through this blog post.

Just 3 months ago I received an email at my inbox from the Outreachy organizers according to which I got selected as an intern at Humanitarian OpenStreetMap Team for the May to August 2023 cohort . And look today my internship is going to end in just two days . So I planned to take you all into a rollercoaster ride of my internship journey .

In the first month I was welcomed by my mentors Rob Savoye and Petya Kangalova where Petya introduced me about the HOT Community . Next I was assigned with many github issues from the projects FMTM and osm-fieldwork by my mentor Rob . I still remember Rob saying me “ Don’t get overwhelmed by seeing the number of issues assigned . Just pick one and start working now and you don’t have to complete all . Take your time and complete only as much as you can comfortably” . These words were so relaxing for me .

Throughout the months of June and July , I and my mentors worked together . I created PRs and they reviewed it , left comments . I worked on them and finally they merged them . One great thing that I always liked and appreciate is that Petya and Rob always respond quickly to my messages and Rob reviews my PRs in seconds in the most perfect way . I also worked with other members of HOT like Kshitij and Omran for another HOT project called fAIr.

In the last month of my internship Petya and Rob offered me an opportunity to be a co-speaker at the Lightning Talk for the FMTM project at Code for All Summit which I accepted and completed . It will be released on 20th September 2023 on Code for All You tube channel and social media handles. Do watch it .

Guten Tag

Ich würde gerne den Bereich des Inselspitals in Bern bearbeiten, weiss aber nicht recht wie. Vielleicht kann mir jemand Tipps geben, wie ich beispielsweise die Spere bei den Gebäudebezeichnungen aufheben kann. Ich bin Mitarbeiter des Spitals und möchte die Karte aktualisieren, so dass die Info auch identisch mit den offiziellen Infos des Amt für Geoinformation Bern. Ich habe in einem Projekt gemeinsam Strassenbezeichnungen, Hausnummern und Gebäude neu benannt. Jetzt muss die Arbeit in den Karten nachgeführt werden.

Freundliche Grüsse

Hi everyone! I am doing my undergraduate studies at Eastern University of Sri Lanka. My course is BA hon’s special in geography. I stared using openstreetmap from 2021 with the guidance of Mr. Sudhaharan sir. In this situation, I grant my heartfelt thank to him. Thank you sir. Now , I am an advanced mapper. I am very happy to share my achievement with you all. In this period, I am working with “El-Nino 2023 Early Warning and Anticipatory Action” project.

‘힘들지만 가치 있는 여행’이라는 말을 들으면 무엇이 떠오르나요? 산티아고 순례길 걷기? 아니면 자전거 전국 일주? 여기 6800마일(약 1만 1000km) 물길을 카약 하나에만 의지해 다닌 사람이 있어요 🛶. 바로 노르웨이 오슬로에 사는 캐나다인 마크 퍼만 씨예요.

올해 65세인 마크 퍼만 씨는 작년 6월에 카약을 타고 출발해 지난 8월 2일에 목적지에 도착했어요. 그가 노를 저은 시간을 다 합치면 1643시간인데요. 무려 68일 연속으로 1초도 쉬지 않고 노를 저은 것과 맞먹는다고 💪. 뭐 바다라도 건넜냐고요? 그건 아니고, 캐나다 동쪽과 미국 동남쪽 마이애미를 잇는 물길인 그레이트 루프(Great Loop)예요. 퍼만 씨는 홀로 카약을 타고 그레이트 루프를 완주한 최초의 사람이 됐고요(그의 이동 경로 📍).

그가 남다른 모험 정신으로 그레이트 루프에 도전한 건 아니에요. ‘국경없는의사회’ 등 자선단체에 기부할 돈을 마련하기 위해서였는데요. 부정적인 것에 압도되어 살아가는 사람들에게 다시 일어설 용기를 주고, 환경 보호 메시지도 전하고 싶었다고. 그는 여행을 마친 뒤 이렇게 말했어요 🗣️: “지옥 같은 여행이었어요. 하지만 고통을 겪을 만한 가치가 있었어요. 후원자와 자연, 내면 깊은 곳과 연결될 수 있었거든요.”

In my last diary entry, I described how I hosted the tile.ourmap.us planet vector tileserver for the OSM Americana project using Amazon Web Services (AWS). This approach is good, but it costs more than necessary and is expensive if you want the tiles to update continuously!

While I was at State of the Map US in Richmond, VA this summer, I ran into Brandon Liu, the creator of protomaps and more importantly, the PMTiles file format. PMTiles provides several advantages over mbtiles which allow us to create an ultra low-cost setup. He shared with me the key elements of this recipe, and I highly recommend his guides for building and hosting tile servers.

With this setup, I am able to run tile.ourmap.us for $1.61 per month, with full-planet updates every 9 hours.

Eliminating things that cost money

The first thing that cost money is running a cloud rendering server. I would spin up a very hefty server with at least 96Gb ram and 64 CPUs, which could render a planet in about a half hour. However, thanks to improvements in planetiler, we can now run planet builds on hardware with less ram (provided there is free disk space), at the expense of the builds taking longer.

I happened to have a Dell Inspiron 5593 laptop lying around that I wasn’t using, because it had a hardware defect where several keys on the keyboard stopped working, even after a keyboard replacement. It had decent specs - an 8-core processor (Intel(R) Core(TM) i7-1065G7), 64Gb of ram, and a 500Gb SSD hard drive. Rather than let it continue to collected dust, I plugged in a keyboard and installed Ubuntu so it could be my new render server.

The story started from https://www.openstreetmap.org/note/3835559, with a small bank in Taitung:

shop=金融服務 ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from https://wiki.openstreetmap.org/wiki/Key:shop fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?

So what exactly, the “池上鄉農會” bank is?

I cannot answer since the Farmers’ Association (農會) is a complicated organisation. I simply don’t know at first. Therefore, I asked a question in OSM Cultural-spheres Group whether countries have such organisations as well:

There’s an agricultural group in Taiwan called “Framers’ Association” (農會) which aims for helping framers like providing farming tools, selling framers products, and providing financial services (i.e. banks) for framers. I noticed that some agricultural groups existed in Japan and Korea. In Japan, it is called “Japan Agricultural Cooperatives” (農業協同組合); while in Korea, it is called “National Agricultural Cooperative Federation” (농업협동조합). My question for folks who live in Japan and Korea: What’s the group do in your country? Like Framers’ Association in Taiwan? How do you map their office? My question for folks who live elsewhere: Do you have similar agricultural group in your countries? If so, how do you map their office?

(In Chinese) Where do your farmers go when they want to buy tools or sell products? Do they go to the local government or private market? What if they need to deposit money? Find a private bank?

事情要從 https://www.openstreetmap.org/note/3835559 這座台東的銀行開始：

https://wiki.openstreetmap.org/wiki/Tag:shop=金融服務 ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from https://wiki.openstreetmap.org/wiki/Key:shop fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?

所以「池上鄉農會」的金融服務，到底是什麼呢？其實我很難回答。因為在臺灣，農會這組織，其實蠻複雜的……我自己一開始也不是很清楚。我只好在 OSM Cultural-spheres Group 問其他成員，其他國家有沒有類似農會的組織。這樣下次解釋起來才好回答。

在台灣，有種組織叫做「農會」，專門提供農民農作工具、把農民的產品賣出去、還有開辦銀行給農民存錢。看了一下，日本與韓國好像也有農業團體：日本叫做「農業協同組合」、韓國叫做「농업협동조합」。對日韓的朋友，我的問題是，這種團體在這些國內做的，也是類似台灣「農會」的工作嗎？這種團體的辦公室、或金融服務，你們會怎麼標？如果是其他國家的朋友，我的問題是，你們的國家有類似台灣「農會」的團體嗎？有的話，會怎麼標？

如果你們的農民想農具、賣產品，怎麼辦？找當地政府、或市場嗎？想存錢呢？與其他人一樣找私人銀行嗎？

臺灣農會

農會以保障農民權益，提高農民知識技能，促進農業現代化，增加生產收益，改善農民生活，發展農村經濟為宗旨。

簡單來說，臺灣農會是臺灣版的農業合作社。不過中間有很多特化。

詳細來說，臺灣農會是幫助農民完成某些任務的團體：比方說農產品宣傳、存錢放款、銷售支援、技術指導等。收入來源不完全來自農民、金融服務、或是農產品，所以不完全等同國外的農業合作社。

在OSM，農會相關服務的地方有：

1. 辦公室：就是給農會員工辦公的地方。
2. 農產品商店：部份農會會收購農民的農產品、然後放到自己開的商店販賣。
3. 農會銀行：就是金融服務。

中國的農業團體

首先，快乐的老鼠宝宝就立刻回我，說沒有類似的組織。

如果是农具或者消耗品如化肥，有专门的农具商店（但是不是私营我不清楚） 存钱取钱随意，不过乡镇上应该只有农村商业银行愿意设网点　卖农产品会有很多贩子到田间地头收，粮食作物可能自己拉去粮站卖　感觉还是非常市场化的

我稍後追問農村商業銀行的性質。透過回答，我發現似乎是某種半國營性質的銀行。但是民間那邊，似乎不是臺灣的農會。

儘管如此，中國有似乎有農業農村部與合作社。只是我沒有深究。

最後是銷售通路。我後來才知道中國有供銷合作社，負責農產品的收購與銷售。似乎還有店面。只是，供銷社在2022重回江湖，有歷久彌新的感覺啊……

韓國的농협

後來띵야告訴我有關韓國的「農業協同組合（농업협동조합）」的歷史背景：

한국은 일본의 ‘농협’을 배워서 만든 것으로 알고 있기 때문에 일본의 ‘농협’과 크게 다르지는 않을 것입니다.

我後來問了農協的大致組成與標記方法：

1. 農產品從當地農民到消費者手中，農業組合會做什麼樣的角色？會自己開店舖賣農產品嗎？還是幫忙把農產品賣給超市？
2. 農業組合的辦公室、或事務所，在 OSM 會怎麼標？金融服務呢？有特別的標法嗎？還是辦公室是 ‵office‵=* 銀行是 ‵amenity=bank‵ ？
3. 農業組合會需要新的 key 嗎？是的話，三國的農業團體能共通嗎？

他的回答如下：

Here is a brief analysis of trends in OSM edits and spatial distribution using compiled statistics from Pascal Neis osmstats website. The link at the bottom of the page will let you download the csv data (by month, quarter / country, region, continent) and make your own analysis.

Thanks to Pascal who provides such usefull infos about OSM activities. As Organized editing statistics have been added to the osmstas website at the beginning of 2022, we will cover the periods from 2022-04 to to 2023-06.

Trends by type of edition

As illustrated on graph 1, there was a small decline of OSM objects edited during this period from 323 millions objects edited in 2022-Q2 to 314 millions in 2023-Q2. This decline comes from the Organized editing with 92 millions objects edited in 2022-Q2 to 54 millions in 2023-Q2 (his share from 28% to 17%).

To start editing OSM, a new user needs to go through a cluttered registration form.

At the same time, vandals easily register thousands of new accounts.

One vandal with an army of bots can paralyze the work of hundreds of mappers in an instant.

At the same time, only the gradual careful work of one person can correctly correct a damaged map.

The project is 19 years old, it’s time to grow up.

昨天挑时间学了怎么画公交，拿了一条线路练手，感觉不错。看到自己画的那条长线在小缩放层级下依然显眼就觉得十分开心。 要开学了呢……赶在开学之前把济宁公交c621a和c621b路画完再把从徐州到济南这一路上所用到的公交线路画完吧。争取不上晚自习这样的话一天多出来了几个小时的空闲时间呢。

Hi all, I’ve made a website which shows how all the waterways in OSM are topologically connected, or not:

OSM River Basins

More details are there, or on the backing github project. You can also run the programmes for yourself if you want to tweak it, or just show your region.

This tool can help you find possible tagging mistakes in river topology, like change in a name, or find places where 2 rivers aren’t properly connected up.

Data is updated manually by me when I remember.

What do yous think?

You can follow me on fedi/mastodon https://www.openstreetmap.org/user/[email protected] for news, or read this on the Discourse OSM Community Forum

I have just realised I should have been adding ‘survey’ as a source in basically all my edits over the last week or so.

I’ve been using RapidEditor to create buildings, matching them with my notes as I walk around exploring my new neighbourhood.

🤦

If you’re not aware, a massive number of accounts have started removing name:ru tags from objects worldwide. Over 4,600 accounts have already been blocked as of the time of writing. I want to bring this situation to the attention of the OSM community that might not use the community forum/discord/etc. and doesn’t know what’s going on.

I don’t really know what to say about this situation or a solution, but it hasn’t been mentioned on-site yet. I hope OSM finds some way to deal with mass-account vandals because mass blocks + detection don’t seem like a sustainable solution, especially with changeset comment abuse, notes abuse, private messages abuse, etc. - the fact that this could happen in the first place is problematic.
