Heritage Week is an annual number of days (it’s longer than a week by now) taking place in August in Ireland. There is a wide array of events including talks, workshops, guided walks etc all around built and natural heritage. This year’s topic was “Living Heritage”.

Recording Milk Churn Stands

Early on in my effort to map milk churn stands in Ireland, I thought that it was not sustainable for me to travel around the country and look for the needle in the haystack, when the locals knew where all the milk churn stands were. So I decided to give a talk which would hopefully raise awareness about the endless possibilities OpenData, OpenSource and OpenStreetMap offers. It was supposed to be a workshop, but I had a funny feeling that the demographic of the audience would turn it into a talk. It actually turned out to be the first event on the Heritage Week website. The Minister for Heritage (, Housing & Electoral Reford) who I happen to be friends with offered to attend, and of course I thought that would be a great opportunity to promote OSM.

The venue was a library in a rural town which used to have a creamery, because I thought it might attract people who remembered the time when milk churn stands (aka creamery stands) were still in use. Once the librarians heard that the minister was attending, they got a bit excited and let the regional library manager know. The big day arrived on August 16th, and he did attend. I had brought the OSM Ireland pull-up poster for the photo op, and also for branding awareness reasons. - So many people still don’t know about OSM, even though everyone by now must have been exposed to it one way or another.

Hi everyone,

I am thrilled to present the final updates on my ongoing project focused on enhancing the search experience in Japan. For reference, you can find the previous blog entry here and the interim report here. In the last interim report, I introduced the changes related to the sanitizer. The associated pull requests for these changes can be accessed here. Regarding this article, you can find the pull request for this specific change here.

In this final update, I will provide detailed insights into our efforts in the “Address Search” realm, specifically related to the tokenizer.

Enhancements in Address Search Methods in Japanese

Japanese Addresses are written in one large string without spaces and Nominatim needs help to find the words. As an illustration, for instance, consider the Japanese address “東京都新宿区西新宿２丁目８−１”. Although it lacks spaces, it can be divided into internal segments such as “東京都” (similar to a state or district), “新宿区” (akin to a city), “西新宿” (akin to a town), and “２丁目” (a block). However, Nominatim only divides such addresses using ICU (International Components for Unicode) transliteration, not based on this semantic division. Fig.1 illustrates a debugging example with multiple potential candidates.

La Cuidadora

“La Cuidadora es un sistema de monitoreo y sistematización de atentados contra los derechos humanos. La plataforma se desenvuelve de forma colaborativa y abierta, pudiendo cualquiera de los usuarios subir un caso de manera anónima. Funciona como un mapa interactivo en el que se pude geolocalizar el punto exacto o referencial del hecho, además de poder recopilarse una serie de datos en las viñetas, desde el nombre de los actores y la descripción del evento hasta el día en el que ocurrió.”

OpenStreetMap como una política educativa global: Aprendizajes desde el Perú

Hace meses publiqué mi primer artículo sobre mis impresiones y perplejidades al respecto de OpenStreetMap, espero sean de utilidad para la comunidad, sino, pues lo intenté, me gustaría iniciar una literatura entera sobre OSM en el Perú, solo estoy pensando en voz alta. Aquí link:

Project name: Guidelines for mapping of wetlands and floodzones. Case study of Lower Sinu river basin in Caribean region of Colombia

Description

The goal of the project is to test the mapping case study to build a document with guidelines for mapping in this areas. It comes from the experience of the “Water telling stories” Social Movement, a root social initiative of near 47 communities, grassroots organizations from 5 municipalities around the ecosystem of the Lower Sinu River Basin, located in the north coastal side of the Cordoba Department, in the Caribean region of Colombia. As part of the technical support team of the movement, Iḿ leading the mapping project for this area.

More info:

I used the jamboard to put one the difficulties from my side:

“I can’t find allies for my legacy project from my OSM local and regional Community. I need people to help me to identify the needs of mapping wetlands and flood areas.”

I’m working with one volunteer from Youth mappers in Colombia who is interested in help to this mapping project. As I said in my diary entry, previously I had lead one mapping session to invite people to join our tasking manager mapping task to map Bajo Sinu “Lower Sinu River basin”.

In my action plan I have:

Réseaux de carrefours

Dans beaucoup de régions les offices de tourisme proposent des boucles de randonnées décrites dans des topoguides imprimés ou accessibles sur intenet.
La plupart du temps, sur le terrain ces boucles sont complétées par des itinéraires de liaison, balisés aussi, mais il est souvent difficile d’en trouver une cartographie détaillée. Des panneaux Info rando dans les villages montrent que l’ensemble boucles + liaisons forme en fait un réseau de carrefours : tronçons balisés reliant deux carrefours indiqués par des poteaux.

Depuis quelque temps, des contributeurs d’OpenStreetMap travaillent à intégrer ces réseaux de carrefours dans la base de données OpenStreetMap. Pour ma part, j’ai intégré une bonne partie du réseau en Ardèche Sud (plus de 1700 km actuellement).

Ces réseaux apparaissent dans plusieurs visualisations : Waymarkedtrails, Knooppuntnet, Thunderforest outdoors…

J’ai par ailleurs développé un outil, basé sur Leaflet, permettant de visualiser ces réseaux sur différents fonds de carte, de construire de proche en proche un itinéraire personnel dans le réseau puis de l’exporter sous forme de fichier GPX. Voir par exemple le réseau Ardèche Sud : Itinéraires Ardèche Sud.

Moyennant quelques requêtes Overpass, cet outil peut être adapté à n’importe quel réseau de carrefours.

Lichaam binnen een straal van 1 km gevonden.

Summary of the situation

Current mapping is inadequate. I have some idea how to make it better, but I am not so sure just yet.

You will smiling, but yes. Again vandalism. Thousands of obscene names have been added to the map. Entire cities were flooded with offensive expressions. I have never seen so huge vandalism.

I thank everyone who worked on solving this problem. You do the good job. Thank you very much.

I found myself down a rabbit hole searching for a good tool for a specific use-case today. The use case is trying to send someone a link to a specific geographic area. My use-case was for directing another person to a specific meetup spot (“meet me over here by the northeast corner of the parking lot”), which doesn’t need to be a point but could be something like a 10x10 foot square and still get the point across. Additionally, there’s a use-case for it in leaving “map notes” within the OSM system: some notes need to indicate very precisely “there’s a missing feature RIGHT HERE”, but others could be more general (“this area is a forest”), and if the note could be tied to a zone, that could be more helpful.

I have used what3words in the past for this, and that site has a nice, short URI scheme to share with people, but the map layers don’t include OSM options, so I started looking for ways to combine the two. That lead me to the wiki page that highlighted many shortcomings with that system (as it’s a centralized, copywritten service). So I went hunting for other systems that could fill the same need of sending people a nice link to “meet me here” (small area) or “I live here” (building-sized area), with OSM tile data under it.

Of the many options for “geohash”-style approximations of latitude/longitude, it seems “Plus Codes” (formerly “Open Location Codes”, OLC) have gained traction as a way to refer to small and large geographic areas, but the main https://plus.codes/map site (the key one that allows seeing a visualization of the grid system, so you know how big a region you’re referring to) only uses Google Maps tiles as the underlying visual, so aesthetically is the same as what3words (telling someone “meet me at the corner of the parking lot here:” with https://plus.codes/86MG4JJJ+HHR is essentially the same experience as giving them https://w3w.co/handy.lame.treats).

Since a few month, uMap has been integrated in a French state incubator, so things are moving quite a lot!

uMap is now ten years old, and is deployed on many instances around the world. The one I know well is hosted by OSM France, and is close to reach one million maps created and 100.000 users.

This incubation program is ported by the French “Accélérateur d’initiatives citoyennes”, it includes coaches and a small budget for non tech needs (UI/UX…). One goal of this program is to find financial support for uMap development and maintainance. A French administration, the Agence pour la cohésion des territoires, is the first uMap financial backer since a few months. This allowed us to put up a small team to work, part time, in uMap:

• two devs: David Larlet and myself
• a UX designer: Aurélie Jallut
• a bizdev, which is yet to hire (interested ? Contact me!)

That’s great news! Until then, uMap was 100% developed on my spare time.

uMap is used a lot by French public agents, and this explains the support from the French state, to make this tool better, and more official. For this, a first step is an “official” instance for public workers:

https://umap.incubateur.anct.gouv.fr/fr/

We’ll be at the NEC - Numérique En Communs event (Bordeaux, France), on October 19th and 20th. See you there for more news and announcements!

What’s new in uMap, then ?

First, a huge cleaning, upgrade and bug fight in uMap code. Since a few years, my time available for uMap has been very low (I’ve been a baker for two years…), so the code urgently needed more love.

What else? Here are a few of the notable changes made recently in uMap, let’s go!

Tl;dr

Dieser Beitrag erklärt, wie sich ein Radnetz, das durch Wegweiser ausgeschildert ist, in OSM abbilden lässt und wie ein Routing-Algorithmus diese Informationen nutzen kann.

Zunächst wird die Grundidee erläutert. Dann folgt ein Vorschlag zum EIntrag in OSM und die dafür erforlichen Tags auf Relationen, Ways und Nodes. Die erforlichen Rollen der Mitglieder der Relation und ihre Reihenfolg werden vorgestellt; dies schließt die Behandlung einiger Sonderfälle ein.

Eine mögliche Nutzung zum Routing auf diesem Radnetz und die dafür erforlichen Voraussetzungen wird diskutiert.

Grundidee

Die grundsätzliche Idee des Basisnetzes liegt darin, dass es miteinander verbundene Wege gibt, die jeweils von einem Kreuzungspunkt zu einem anderen Kreuzungspunkt führen und zusammen ein Netz bilden. Zu diesen Kreuzungspunkten gehören Wegweiser. Für Radverkehrsnetze sind dies Radwegweiser.

In OSM sind die Wegweiser als Node u.a. mit dem Tag information=guidepost abgebildet.

Wegweiser

An jedem Kreuzungspunkt steht mindestens ein Rad-Wegweiser, es können aber auch mehrere sein. Dies tritt in der Regel immer dann auf, wenn die Wegweiser die Form der Tabellenwegweiser haben.

Auf dem Wegweiser sind mindestens zwei Ziele angegeben und die Himmelsrichtungen der Ziele sind bekannt. Sie sind in der Form direction_* angegeben und bezeichnen 8 mögliche Himmerichtungen in 45° Grad-Schritten von northeast über east bis north in englischer Sprache. Siehe hierzu DE:Tag:information=guidepost – OpenStreetMap Wiki

Wege

EIn Weg bezeichnet in diesem Beitrag eine Verbindungen innerhalb des Radnetzes von Kreuzungspunkt zu Kreuzungspunkt. Er kann aus mehreren Teilstücken bestehen.

Die Wege sind in der Regel in beiden Richtungen befahrbar, also vom Anfang zum Ende und vom Ende zum Anfang. Der Hinweg führt vom Anfang zum Ende, der Rückweg vom Ende zum Anfang.

Teilstücke, die nur zum Hinweg oder Rückweg gehören nicht jedoch zu beiden, werden besonders gekennzeichnet.

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
