Hi everyone,

I’m currently using the Valhalla API for routing, and I recently started experiencing some issues (e.g., slow responses / failed requests / unexpected results).

The issue occurred on May 4th at around 5:15 PM (Egypt time, UTC+2).

I wanted to check if there is any ongoing outage or known issue with the service at that time.

If anyone else faced similar behavior or has any insights, I’d really appreciate your help.

Thanks in advance!

Os alunos da Escola Secundária Jerónimo Emiliano de Andrade (https://esjea.edu.azores.gov.pt/), dos cursos de Técnico de Serviços Jurídicos e Técnico de Ação Educativa 1, decidiram que a melhor maneira de comemorar os 50 anos de Autonomia da Região Autónoma dos Açores era criar uma viagem por alguns dos lugares que contribuíram e contribuem para uma autonomia cada vez mais forte. Assim nasceu este mapa: (https://umap.openstreetmap.fr/pt-pt/map/viagem-pelos-lugares-da-autonomia-acoriana_1394943#5/50.750359/-0.219727)…

Every three years introvert communities from three Baltic countries try to gather together in one city and discuss things they’ve been doing. It is called SotM Baltics, and this year the conference comes again to Riga, Latvia. It’s in less than a month: 4th of June!

We’ve got just one day, and not a weekend even. But there will be many GIS professionals in neighbouring rooms (with their own conference), and generally the event will definitely feel like an oasis of open mapping.

I would like to invite you — whether you live nearby, or can fly in for a couple days — to attend and maybe present at the conference. There will be video recordings, and more importantly, a free lunch for everyone. And both the city and the weather promise to be splendid.

See the website for info and forms: https://2026.sotm-baltics.org/

For the next day I’m thinking of organizing either a workshop or a bicycle ride, whichever looks more fun.

Hello

1999 and tomorrow it’s 2000, deus volente, and HAL goes off the year after.

Today I did mapping in Baucau. I added some new roads and buildings that are not in OpenStreetMap. I am happy to be able to help the community get a better map.

Hello,

Below I have compiled recent news related to the OSM Foundation (OSMF) board’s work. Most of these are or are going to be publicly documented on the OSMF website, so if you follow the Atom feed for the board meetings’ page, you can skip this.

What this diary entry is

It contains my personal selection and recollection of recent OSMF board-related updates.

What this diary entry is not

It is not intended to include details or all OSMF board-related updates. For these, you can refer to the published board minutes. This entry has not been reviewed by the OSMF board.

Why?

Informing the OSMF members is important. The board minutes describe in detail what was discussed in public board meetings, but many people don’t have time or follow the Atom feed for the OSMF’s website recent changes. At some point, I was creating annual or more frequent updates for the whole Foundation, which was a lot of work during a short period, while other tasks were ongoing.

I’m posting this experimentally, and I’m going to see whether I can continue to do so semi-regularly.

2026 OSMF budget

The 2026 budget of the OSM Foundation is now published. You can find previous budgets here. Please note that the board may revise the budget throughout the year.

April 2026 OSMF board updates

The board had a meeting on Thursday, 30 April 2026.

You can read the Secretary’s report by Dani Waltersdorfer and the Treasurer’s report by Roland Olbricht.

OSMF’s move to the EU

Craig Allan (Chair) committed to informing the community about the status of the OSMF’s move to the EU, after a comment by Simon Poole (former OSMF and LWG chair) during the April board meeting.

OSM Local Chapters and regional communities

OSM US Inc: The OSM US and OSMF Boards had a closed, introductory meeting on 2026-04-09. The OSMF board, after a comment by imagico (guest) during the April board meeting, said that it is open to meeting with other OSM Local Chapters, if they are interested.

OSM France: Apologies were expressed again to OSM France during the April board meeting (previous apology on February 2026), as the board did not inform them about the communications with the French Cadastre.

Presentations during OSMF board meetings: The board wants to restart presentations by Local Chapters and communities during board meetings (previous presentations). If you are interested, please email the board at the address mentioned here.

OSMF Corporate Members

Héctor Ochoa Ortiz (Deputy Secretary) had a private meeting with TomTom (Corporate Member) to discuss their intention to share information with the OSM community regarding their detection of potential vandalism and problematic edits. Héctor pointed them to the Data Working Group. rphyrin (guest) suggested that OSMF (and TomTom) could facilitate a community discussion to address this issue together.

Financial

2026 fundraising drive: The board will hold a closed chat on 2026-05-07 to discuss fundraising communications for the proposed 2026 fundraising drive.

BTC: The board decided to use Monetum as a service to exchange Bitcoin donations to fiat. The OSMF’s BTC address is this one.

OSMF bank accounts: The Treasurer has already regained access to the main Bank of Ireland account and is working to regain access to the Fire EU account.

Contract extensions: The board extended the contracts of Martin Raifer’s (iD maintainer) and myself (assistant to the OSMF board).

Operations

QGIS tile server load: On average, QGIS users access more OSMF tiles daily than users of osm.org. Some OSMF people are in contact with the QGIS board. Suggestions include upgrading the QGIS Corporate Membership to Platinum, or buying OSMF a server dedicated to their traffic.

State of the Map (SotM) 2026

The board decided to finance the travel of the three Sovereign Tech Fund contractors to attend the State of the Map (SotM) 2026 conference.

Board members’ participation at external meetings

2026-04-20: Dani Waltersdorfer Jimenez (Secretary) was invited by the US National Academies of Sciences, Engineering, and Medicine, and on 2026-04-20 gave a presentation and participated in discussions during the Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD) meeting of experts.

2026-05-01: Héctor Ochoa Ortiz attended the 2026 Geospatial World Forum and participated in the GKI Summit 2026-05-01 panel discussion “Scaling GKI: Public–Private Partnerships and Cross-Agency Delivery Models”. Héctor mentioned that there were discussions about bot usage/scraping at the conference and that he might post a diary entry. OSMF was offered a free ticket to participate.

2026-06-19: Héctor Ochoa Ortiz, together with Yannick Brosseau (OSM community member in Canada), will facilitate an OSM online mapathon organised by Gore Mutual (Canada) for their employees. The company will offer a €1,450 honorarium to OSMF.

2026 Board face-to-face (F2F) meeting in June

Six of the seven board members will meet in person in Madrid at TomTom’s office, from 6 to 7 June 2026. Unfortunately, Brazil Singh will not be able to attend. The meeting will be facilitated by Aspiration Tech.

The current OSM Foundation board members are:
Brazil Singh 🇧🇩
Craig Allan 🇿🇦
Daniela Waltersdorfer 🇵🇪
Héctor Ochoa Ortiz 🇪🇸
Laura Mugeha 🇰🇪
Maurizio Napolitano 🇮🇹 and
Roland Olbricht 🇩🇪.

Read their biographies and find out their officer and other roles.

OSMF board members are volunteers.

Minutes of public OSMF board meetings are on the OSMF website.

I would also like to take this opportunity to thank the weeklyOSM volunteers, including those who attend the OSMF public board meetings, as well as the community members who submit news to the weekly :)

在画地图时，我们往往离不开一个很重要的地标——祠堂。我先假设各位朋友们都明白祠堂对于一个村庄或一个镇街，在地理上与历史文化上的重要意义，因此就跳过解释（如果你需要了解它，这里是维基百科的链接）。总而言之，它的重要程度足以在OSM上拥有一个标记。不过，寻找一个适合它的tag，却成为了一个难题。

参考现有的例子

我先参考了OSM上，中港台三地现有的祠堂，以及它们的tag。

amenity=place_of_worship

例子有：宗祠 Ancestral Hall、劉氏家祠 Lau’s Ancestral Hall、五福堂 Ancestral Hall、宗祠、朱厝宗祠、鄭氏祠堂、祠堂、祠。

landuse=religious

例子有：扬氏宗祠、隴西堂(彭氏祠堂)、余氏宗祠、邱氏宗祠-明德堂、谢氏大宗祠。

religion=chinese_folk

例子有：劉氏家祠 Lau’s Ancestral Hall、宗祠、余氏宗祠、扬氏宗祠。

amenity=community_centre

例子有：宗祠、宗祠。

结论

从我收集到的例子来看，OSM上对祠堂的标注，多数为amenity=place_of_worship以及landuse=religious，而部分祠堂会附带religion=chinese_folk的key。这些标注初看是挺合适的，但是仔细揣摩，我发觉这并不完全准确。

这些标注更适合宗教场所。而祠堂，在文化意义上是供奉和祭祀祖先的场所，而祖先崇拜并非为一种宗教。至于religion=chinese_folk，它通常指的是中国民间信仰。虽然有些民间信仰会与祖先崇拜混合，有些祠堂会举行民间信仰的崇拜活动，但这并不代表着所有祠堂内举行的活动都有带有民间宗教信仰的成分。

有部分祠堂的标注为amenity=community_centre，这其实也反应了祠堂的另一些功能：宗族成员的聚集活动场所，比如节庆宴饮、婚丧寿喜，等等。

祠堂在OSM上难以寻找到一个合适的tag，其实就体现了一种文化上的差异——OSM来自英国，大部分OSM贡献者也来自欧美地区。它的tag和key的设置，就是默认以欧美地区的文化为基础的。而对于中港台等东亚文化地区的地图绘制，那些普适性的，比如交通设施、商业建筑、住宅、学校、公园等等，往往没有什么问题。但是当我们要标注东亚文化圈内特有的文化现象——比如祠堂——问题就出现了。

我会希望我们能够自定义一个tag，比如amenity=ancestral_hall之类的，这样的标注，会比使用多个模棱两可的标注，准确得多。

现有的解决办法：building=shrine？

我翻查了OSM Wiki，找到了building=shrine这一个tag。根据OSM Wiki对它的定义，这似乎就是目前为止最适合祠堂的tag了。

说在最后

我没有想到，对于祠堂的tag的探寻，会成为一个跨文化语境下的迷你研究。此外，我在OSM Wiki上，有找到对于牌坊的标注，感觉很有意思：

man_made=ceremonial_gate
ceremonial_gate=paifang

牌坊能够拥有一个专属的标签，祠堂，是否也能拥有呢？

Mapping

• Comments are requested on this proposal:
  • terminal=yes to consistently map goods terminals and better describe connected transport modes and handled cargo.
• The following proposal is up for a vote:
  • highway=service + service=safari to map dedicated service roads in safari parks.

Community

• In an interview on the OpenCage Blog, Christian Quest outlined plans for the Panoramax Foundation to coordinate an open federated street-level imagery platform. The initiative aims to foster international collaboration and draws inspiration from the OpenStreetMap Foundation.
• Christian Quest has reminded us that the Panoramax instance run by OSM France accepts images from outside France for testing purposes only. However, almost half of all images are from foreign countries. He warned that the board of OSM France will decide soon whether to delete those pictures, because disk space is running out. According to recent figures, the Panoramax federation has grown to 10 instances, which now hosts over 100 million openly licensed street-level images contributed by more than 2,000 users. This was celebrated by Bastian Greshake Tzovaras on Mastodon.
• 9_tab wrote about Quartiers de Genève in their OSM User Diary. A mapping sprint around Geneva has organised the place=* nodes and local data for neighbourhoods and quarters has been compared with those mapped.

OpenStreetMap Foundation

• The OpenStreetMap Foundation has published its 2026 budget, approved in January, projecting around GBP 822,000 in income and about GBP 933,000 in expenditure. It includes funding for staff, contractors, microgrants, and infrastructure. It may be revised during the year.
• The OSMF has documented the short presentations given during public board meetings and is considering reviving these community talks in 2026. The ten-minute slots provide insights into projects and initiatives from the OSM community.

Events

• Silvina Meritano and Bastian Greshake Tzovaras gave a talk about OSM at the Latinamerican Festival for Free Software Installation in Córdoba. Their slides and materials are available online.
• An OSM Hackweekend in Karlsruhe (Germany) has been announced for 26 and 27 September 2026. This event invites developers and contributors to participate in projects related to OpenStreetMap.
• The call for papers for OSM Science 2026 has been extended. The conference will take place as part of State of the Map 2026, which will be held in Paris.
• The Wikidata and OpenStreetMap Taiwan communities have called for proposals for the joint State of the Map Taiwan 2026 / Wikidata Community Summit track at COSCUP. Submissions on topics such as Open Data, linked data, and OSM are open until Saturday 9 May.

Education

• IVIDES.org and IVIDES DATA are offering an opportunity of two paid vacancies to update and translate the content of the IVIDES.org’s OpenStreetMap course into English (can be either American or British) and Spanish. Please consult / the conditions and send your letter of intent by Friday 8 May.
• IVIDES DATA is now accepting registrations for its 2026 OpenStreetMap Workshop series (which will be in Portuguese), which consists of five sessions covering a variety of topics, such as mapping with OSM, QGIS plugins, web forms with KoboToolbox, and web maps with uMap. The focus of this edition of the series is to provide participants with the tools they need to develop a small practical project. The organisers believe that, in this way, the knowledge gained through these free software tools can be better integrated by the participants.

OSM research

• HeiGIT presented a study on automated road crack localisation for highway maintenance, using network data extracted from OpenStreetMap to enable spatially guided analysis and improve infrastructure monitoring. The study was published in Transactions in GIS30 and was authored by Knoblauch, Muthusamy, Ghamis, and Zipf.

Maps

• Christoph Hormann has proposed changing how OpenStreetMap Carto determines the name of a feature when labelling it on the map.
• The Deutsche Digitale Bibliothek (German Digital Library) has published a thematic ► web map of right-wing extremist violence in Germany since 1945, linked to the library’s archives from Archivportal-D. The map’s layers are based on OpenStreetMap or OpenHistoricalMap, depending on the time period.

OSM in action

• ^[1] Zoe Skyforest reported on Hackaday about a new national pastime in Australia: the sport of Payphone Tag. Developed by Alex Allchin, it is a capture-the-flag game in which players dial a number using local public phones to capture the area surrounding them. A real-time map of territories held by players is displayed via an OpenStreetMap-based web map. There have been 800 players in the last seven days and a total of 36,640 captures so far.
• Leonardo Texidó Quintana has developed a ride-hailing application for Cuba by leveraging OpenStreetMap data and forking Organic Maps for both passenger and driver apps. This app has facilitated more than 20,000 real taxi trips during a fuel crisis, operating on low-end smartphones with 2GB of RAM and intermittent 2G connectivity.

Open Data

• GOWIRES is a new open dataset combining location data from over 400,000 wind turbines worldwide (across 89 countries) with historical and future wind resource data. The geographic data is largely based on OpenStreetMap and has been validated against national registries.
• OCHA Centre for Humanitarian Data has published a global dataset of sub-national administrative boundaries for 110 countries.

Software

• In response to recent issues with the public Overpass servers, Kai Johnson has published a new Docker container image for Overpass, allowing people to run their own Overpass instances.
• HeiGIT has announced that their URL api.openrouteservice.org is being deprecated in favour of api.heigit.org. While the services remain unchanged, users need to update their applications before the shutdown in August 2026.
• geoObserver has showcased ► DrawonMaps. This is a web app that detects the edges of an uploaded image, then traces and fills the image using the OpenStreetMap street network.
• GéoDataMine has made it easy to extract ► thematic data from OpenStreetMap in the form of spreadsheets or geographic files. The data is updated daily and made available in CSV, GeoJSON, XSLX, and Shapefile formats. It is made compatible with national data schemas where they exist; otherwise, it follows OpenStreetMap conventions.
• Ilya Zverev has noted that a ticket regarding the support of multiple accounts in JOSM, which had been open for 15 years, has been closed with the status ‘won’t fix’. Consequently, there will continue to be no native support for multiple user accounts in JOSM. Some users are getting around this limitation with personal scripts, such as reported by M!dgard for *NIX systems. An alternative method that also works for Windows is available .
• The members of the osm2pgsql project announced that they recently won a grant from the NGI0 Commons Fund to work on the Compact OpenStreetMap Data Archive project (tentative name), aimed at reducing the memory and disk usage of osm2pgsql by implementing more efficient storage formats.
• The OpenGridWorks project, led ► by Alejandro Polanco, shows energy infrastructure and uses CARTO and OpenStreetMap for its reference geospatial layers. The available layers include power stations, transmission lines, substations, gas pipelines, data centres, planned transmission projects, submarine cable routes, and flood risk.

Programming

• Candid Dauth has introduced a new fork of openstreetmap-tile-server, which separates database and rendering, while supporting modern osm2pgsql features. This approach aims to enable more flexible and efficient tile hosting with incremental updates.
• Evgeny Arbatov has developed ‘vibe mapping’, a pipeline that analyses the overall vibe of a place using OpenStreetMap data. From the OSM data extract it divides an area into H3 hexagons, then calculates aggregate metrics for each hexagon. Based on these metrics, it asks an AI model to generate a short, one-sentence description of the place’s vibe. The code is available on GitHub.
• NieWnen has published a script that filters OSM replication files using .poly boundaries, to keep regional databases updated with osm2pgsql. This approach offers an alternative to Overpass and enables more flexible self-hosted data processing. The code is available on GitHub.
• Mark Litwintschik presented a reverse geocoding prototype based on Overture Maps that retrieves country codes and nearest addresses without external APIs. The underlying datasets also include OpenStreetMap data and are processed locally.

Releases

• Nils Nolde has released Valhalla 3.7.0, introducing features such as multimodal routing, OSM XML support, and additional metadata. This release also included numerous bug fixes and changes to routing and data processing components.
• Route-Crafter version 0.2.4 has improved the handling of very long routes, fixed mobile UI issues, and added warnings when settings change. It also updated features for setting the start location button and improved the route player traversed line visualisation.
• Marcus Jaschen has published a new route manager for Bikerouter, allowing users to store and organise routes either in the browser or on servers.

Did you know that …

• … Bikemap.net allows users to plan cycling routes worldwide using OpenStreetMap data for routing and maps?
• … Skaringa has developed a map of river basins in Central Europe using OpenStreetMap waterway network data?

OSM in the media

• A recent ► comparison of online cycling route planners highlighted Bikerouter (based on BRouter) as a powerful and fully free tool with extensive routing options and OSM-based maps. Bikerouter.de, created by Marcus Jaschen, relies ► on OpenStreetMap data for accurate routing and offers advanced customisation and export formats such as GPX or GeoJSON.
• An article by Anna Biselli, on netzpolitik.org, presented ► some privacy-friendly alternatives to commercial navigation apps, including several based on OpenStreetMap. The article highlighted decentralised approaches and offline use as key advantages.
• The Rail Agenda noticed in Substack that Oxford and Cambridge have no direct rail link today after the closure of the Varsity Line in the 1960s. The proposed East West Rail would restore one, with four trains per hour on the full corridor. The post is illustrated with an OSM map and used Wikimedia Commons data.
• Joe Fedewa took a look at StreetComplete, which rewards users with points for contributing to the improvement of OpenStreetMap. The concept is intended to create additional incentives to supplement and correct local map data.

Other “geo” things

• Crust News has noticed that Apple Maps no longer displays the names of various towns and villages across Lebanon. The removal is not limited to the area of the country facing Israeli invasion and attacks, it applies nationwide. Only a handful of larger cities remain labeled: Beirut, Tyre, Sidon, and a small number of others.
• The city of Porto will host ► the 17th Iberian Conference on Spatial Data Infrastructures, which will take place from 11 to 13 November 2026. For the theme of spatial data infrastructure in a changing world, the event has issued an open call ► for the submission of papers until Wednesday 10 June.
• The Bathymetric Data Viewer is an interactive map providing a search and discovery service for the bathymetry data and digital elevation models archived at NOAA’s National Centers for Environmental Information. A geoviewer with layers from the IHO Data Centre for Digital Bathymetry is also available.
• According to the proposed ► Emergency Care Reform Act, the German Federal Ministry of Health plans to create a public registry of automated external defibrillators.
• After it had been an EU requirement for two years, Jesper Zedlitz reviewed ► the status of high value datasets in Germany and revealed major differences between federal states. The differences point to gaps, inconsistent implementation, and open questions around categorisation.
• A recent article by Gabrielle Bruney, published in Places Journal, explored the role and decline of public benches in cities, highlighting their social and spatial importance. This article is the latest in a series, Writing the City, a collaboration between Places Journal and the Arts and Culture Program at Columbia Journalism School. For OpenStreetMap this underlines the relevance of detailed mapping of features such as amenity=bench. There is an ongoing proposal (since 2021) for hostile benches as a form of hostile architecture.

前言

这些随想是在去年年底写的，也许对其他 mapper 有启发，故发布。

以下经验会让画 osm 变得高效、美观、简洁，避免无线细化。

正文

1. osm 本质是抽象、简化的地图，所以画面元素要少、整洁。增加过多的元素会导致地图画面杂乱无章、不美观，而且后期维护也很繁琐。

   例：一条公路的两旁有人行道，除非有物理隔离（比如栏杆），否则推荐在道路上加 sidewalk=both，而不是把两旁的人行道都画出来

2. 要提炼出对象特征，想出表达完整又简练的画面布局，同时不要出现渲染错误。

3. 直线要直、圆形要园、方形要方、弧线要优雅大气。

4. 线条不宜有过多节点，尽量把多余的、又不影响整体的节点删掉

5. 道路、河流、森林等图画，宜大不宜小，宜长不宜短，宜整不宜碎

6. 能不重叠就不重叠。如果一片区域（比如小区、医院、学校等），有明确的边界（比如围墙），最好先画完内部道路、建筑设施，最后再画上土地利用 area=yes。否则就不要画。

7. 一般使用 iD 编辑器最简单。若想画整齐的方形建筑物建议用 JOSM，并使用 building 插件。

8. 标签方面，非必要不多加。

前言

这些随想是在去年年底写的，也许对其他 mapper 有启发，故发布。

慎画密集的住宅区

卫星地图上密集的住宅区（不规则的房子、看不清的小巷），除非亲自走访、亲自记录，否则最好不要画

不要无限细化

刚画 osm 时，很容易被卫星地图里的各形各色的东西吸引注意力，导致无限细化，也就是说在一小片地方死抠细节。

若画小范围的地方（比如学校、公园等），无限细化无所谓。但画大范围的地图还无限细化的话，这得画到猴年马月？而且还会打消画 osm 的兴趣。

所以画大范围的地图，在保证效率的同时，还要表达准确。这件事不容易完成。

画 osm 的难点在于：怎么把卫星图像上的东西，提炼成精准、简洁的符号。

请参考 osm 极简画法

Kontribusi Perempuan dalam Pemetaan Dunia

Keberadaan perempuan di dunia kartografi dan pemetaan saat ini semakin terlihat dan jumlahnya terus bertambah. Kontribusi mereka memberikan nilai yang sangat berharga bagi perkembangan data geospasial. Meski demikian, dalam dunia pemetaan sukarela seperti OpenStreetMap (OSM), jumlah pemeta perempuan masih lebih sedikit dibandingkan laki-laki. Padahal, peran pemeta perempuan sangat krusial untuk meningkatkan inklusivitas data, terutama dalam melengkapi informasi fasilitas publik yang spesifik bagi perempuan, seperti ruang laktasi dan toilet umum.

Dasar-Dasar Pemetaan di OpenStreetMap Sebelum mulai berkontribusi, ada beberapa konsep dasar yang perlu dipahami agar data yang dihasilkan akurat dan bermanfaat:

Konsep Objek di OSM:

• Titik (Nodes): Menandai lokasi spesifik.

• Garis (Ways): Untuk objek seperti jalan atau sungai.

• Area (Poligon): Untuk batas bangunan, taman, atau wilayah.

• Relasi (Relations): Untuk menghubungkan objek-objek yang kompleks.

Sistem Tagging (Atribut Data): Pemberian label informasi pada setiap objek.

Sumber Data yang Legal:

• Citra Satelit yang diizinkan.

• Survei Lapangan langsung.

• Data Pemerintah yang bersifat terbuka.

Alat Pemetaan (Editor):

• A list item with additional text

• iD Editor (Berbasis web, ramah pemula).

• JOSM (Untuk penyuntingan tingkat lanjut).

• StreetComplete (Aplikasi seluler untuk pemetaan praktis).

Hal Penting Sebelum Melakukan Digitasi Kemampuan membedakan objek seperti jalan, bangunan, badan air, dan vegetasi adalah inti dari interpretasi citra. Tanpa kemampuan identifikasi yang tepat, data hasil digitasi tidak akan memiliki nilai informasi yang benar. Terakhir, diperlukan kerelaan hati dalam memetakan. Tujuan utama OpenStreetMap adalah menciptakan basis data peta dunia yang gratis, terbuka, dan kolaboratif. Ingatlah bahwa kontribusi ini bersifat sukarela tanpa imbalan materi, namun sangat berdampak besar bagi kemanusiaan dan akses informasi dunia.

Arbuckle is a small community of about 3500 people in southern Colusa County. My husband and I stop through there a few times a year as we head north. It has gas stations and a fantastic Mexican restaurant on 5th street.

So it seemed like a good place to focus on mapping. I have about 100 homes left on the north west corner of the community. I started the project in January on business trip to Chico.

Ungkapan bahwa kehidupan itu “kadang naik kadang turun, kadang kaya kadang miskin” adalah metafora roda kehidupan yang terus berputar. Ini menggambarkan fluktuasi nasib manusia yang tidak abadi, di mana seseorang tidak selamanya berada di atas (sukses/bahagia) atau di bawah (terpuruk/kesusahan). 1. Filosofi Roda BerputarKetidakabadian: Situasi saat ini, baik itu kejayaan maupun kesulitan, adalah sementara.Ujian Kehidupan: Kaya dan miskin adalah bentuk ujian untuk melihat siapa yang bersyukur dan bersabar.Perubahan Nasib: Seseorang yang hari ini kaya bisa saja jatuh miskin, dan sebaliknya, yang miskin bisa menjadi kaya.

1. Sikap Saat di “Atas” (Kaya/Sukses)Tidak Sombong: Jangan merasa angkuh atau lupa diri karena posisi bisa berubah kapan saja.Berbagi & Bersyukur: Kekayaan adalah kesempatan untuk berderma dan membantu sesama.Tetap Membumi: Sadar bahwa semua hanyalah titipan.

2. Sikap Saat di “Bawah” (Miskin/Terpuruk)Bersabar & Tegar: Tidak putus asa karena kesulitan adalah bagian dari proses pendewasaan diri.Berusaha & Berdoa: Tetap berjuang karena roda akan berputar kembali.Fokus pada Solusi: Orang dengan mental tangguh akan mencari peluang, bukan meratapi keadaan.

3. Hikmah di Balik Perputaran Keseimbangan: Adanya kaya dan miskin diciptakan agar roda kehidupan berputar dan manusia saling membutuhkan.Pembelajaran: Pengalaman di titik terendah seringkali melahirkan ketangguhan dan kerendahan hati.Ketenangan Hati: Memahami bahwa “semua akan berlalu” membuat seseorang lebih tenang menghadapi penderitaan.

Secara ringkas, kunci menghadapi roda kehidupan yang berputar adalah bersyukur saat berada di atas, dan bersabar saat berada di bawah.

The rider (driver /occupant / pilot ?) was on his way from Dusseldorf to Shetland. That puts my ride between Hispburn and Druridge Country Park into some perspective. But then I enjoyed a ride of a couple of hours on a sunny day. With a slight headwind on the way out. And a tailwind on the way back. He was on a three month trip.

It looks as though one of these can achieve an impressive speed on a suitable surface. However, there are several sections of NCN-1 which must have been difficult for him to negotiate. I imagine that narrow gaps, steep climbs, sharp turns and rough surfaces will be more tricky for him than they are for me. So we met up and parted several times between Amble and Hipsburn.

Such an unusual vehicle attracts a lot of attention. But it can't be easy to get into. And if I ever did get into one of these I'm not sure I would ever get out again. I think I'll stick with a more conventional folding bike.

While browsing Taginfo I got curious how many elements have at least one key described on the Wiki and how big share of all keys the described ones make up. Therefore, I decided to check it out.

The analysis consisted of the following parts:

1. fetching OSM database dump from planet.osm.org;
2. fetching key statistics from Taginfo with the API;
3. extracting “is in Wiki” info into separate file;
4. altering “is in Wiki” info for keys which were described on the Wiki after the database was dumped. The alteration was based on the recent changes registry;
5. processing the dump with DuckDB:
   • extracting element type, its ID, and its tags to new table: CREATE TABLE elements AS SELECT kind, id, tags FROM ST_READOSM('planet-latest.osm.pbf');;
   • exploding keys to separate records: CREATE TABLE elements_keys AS SELECT kind, id, UNNEST(map_keys(tags)) FROM elements;;
6. querying the database.

These are queries I provided to DuckDB:

I got the following results:

• all elements: 11,759,061,283
  • of which are tagged: 1,459,875,801 (12.415% of all elements)
    • of which have a key described on the Wiki: 1,459,659,709 (99.985% of all tagged elements)
• all keys: 109,269
  • of which are described on the Wiki: 5,865 (5.367% of all keys)

The analysis provided the following conclusions:

• small amount of Wiki-described keys represent nearly all tagged elements, which follows Pareto principle;
• “any tags you like” rule does pose no significant threat to tagging consistency, since there is at least one known way to get info about virtually every element;
• there is always a room for improvement for keys in terms of being described on the Wiki, especially for those that are a more precise version of the described ones.

The results are valid as of 20th April 2026, 12:00 AM, when the OSM database was dumped.
