Sto mappando la città in cui abito, Piombino. Nella scorsa settimana ho aggiunto quasi 7000 punti tra marciapiedi, strisce pedonali, panchine, cestini, pali della pubblica illuminazione, etc.

Perché lo faccio? Beh, innanzitutto perché Google, con le sue politiche sull’accesso ai dati che sono stati volutamente aggiunti dagli utenti e non da Google stessa, può andare a fare in culo. In secondo luogo, anche se Piombino è una città relativamente piccola, voglio che abbia le mappe più dettagliate e accessibili possibile. Infine, dato che utilizzo OSM nei miei progetti, volevo restituire qualcosa alla comunità, spargendo anche la voce che esiste e che è importante aggiungere la propria attività non solo su Google Maps, ma soprattutto su OSM.

In questa prima fase sto aggiungendo punti a destra e a sinistra e credo di aver già fatto un buon lavoro. Le fasi successive, però, sono ancora più importanti: l’aggiunta dei metadati agli elementi mappati e la ricostruzione degli edifici da zero (questi ultimi sono stati mappati 14 anni fa).

E niente, mandate a fare in culo Google, monopolista di dati che non sono suoi. Contribuite ai progetti open source, che permettono alle persone di costruire nuovi progetti basandosi su di essi.

Validating the work of others is important. I was creative in doing just that.

completed survey of all speed limits in an area south of Palatine Road, east of Wilke, west of Arlington Heights Road and north of Euclid/Northwest Highway. Updated street data on the map.

愛知県尾張旭市内のバス停・バス路線のマッピングを進めています。 コミュニティバス「あさぴー号」の停留所について不明点が残っているため、1週間以内に現地調査に行きたいです。 また、瀬戸市内の商店街にある店舗についても、営業時間などの情報を調べてマッピングを進めていきたいと思います。

bonjour, comment metre à jour le parcours eurovelo 6 qui n’es pas à jour ? ( peut-etre d’autres aussi, mais c’est celui que je fait en ce moment ) importer les traces GPX du site Eurovelo ne marche pas ( pb de dates dans fichiers) .

merci de vos commentaires

최근에 현체로 경주월드 다녀왔거든요? 가기 한 이틀 전에 osm 드가서 경주월드 편집하는데 타카티스크?? (2022년에 운행 중단) 서라벌관람차?? (2022년 8월에 철거) 처음 들어본 게 많아서 당황했습니다. (심지어 타카티스크가 아니라 타가디스코임) 어쨌든 중요한 지물들을 편집했습니다. (미로탐험 없애고, 타임라이더 만들고 등등) 근데 잼민이인 저 혼자 하긴 너무 힘든거 같아서 제발 도와주시면 좋겠습니다 ㅠㅠ

This is a very simple idea: given a set of GPX traces for a hike you are planning to take, generate a file containing all the waypoints of interest within the area covered by the GPX traces. I create a buffer around the GPX traces and extract the area from OSM. I define a set of tags of interest. I use Ollama with Mistral Nemo to make sure that POIs make sense to visit while walking on foot, as places are sometimes mislabeled in OSM. Before saving the waypoints to a GPX file, I use Ollama again to generate waypoint descriptions and set labels for each waypoint. Feel free to try it out! The code is on GitHub.

Mapping Sitka is pretty much my identity. I was upset when someone reverted my work because honestly I’ve been working every waking hour for a few months now. It was good though because I needed to step back and not take it too seriously. I’ve had some manic episodes late in life and they unlocked some anger I’m not familiar with. It was actually impressive how mad I got. Anyway, what are these diaries for if not a super personal post? Stay mappy people

Earlier today I had to check an alarm on the servers. The alarm was for a non-issue, but I happened to notice a momentary delay to replication across multiple services and I wanted to investigate.

The rendering servers fell up to four minutes behind on some servers, with all servers falling at least a minute behind normal. Interestingly, there does not seem to be a correlation between the delay and the server capacity.

Manchmal ist Wikimedia Commons eine gute Quelle für Objekte, die in OpenStreetMap fehlen, und manchmal ist es umgekehrt.

Aber wie lassen sich Informationen aus beiden schnell verbinden und am besten noch visualisieren?

Der naive Ansatz

💡 Daten per Abfrage aus Commons und OSM holen und in uMap anzeigen.

🏁 Als Beispiel möchte ich hier alle Ortseingangsschilder aus Sachsen-Anhalt visualisieren.

Naiv bedeutet hier natürlich auch, dass in Commons nicht alle Bilder ihre Standorte koodiert haben.

Wikimedia Commons mit PetScan abfragen

Wikimedia Commons bietet mit PetScan ein Tool an, das unter anderem auch nach KML exportiert. Ein Dateiformat, das nach uMap importiert werden kann. Folgende Parameter erzeugen in PetScan nach einem Klick auf “Do It” eine KML-Datei mit den entsprechenden Geo-Informationen:

Parameter	Wert
Language	commons
Project	wikimedia
Depth	1
Categories	Zeichen 310 in Saxony-Anhalt
Page Properties: Namespaces	Commons, File
Output: Format	KML
Output: Page Metadata	Image, Coordinates, Default sort

Wichtig ist auch Depth auf größer 0 zu setzen, damit untergeordnete Kategorien miteinbezogen werden, so dass z.B. auch Ortseingangsschilder aus dem Saalekreis gefunden werden.

Der Inhalt der KML sieht dann ungefähr so aus:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
  <Document>
    <Placemark>
      <name>Hundeluft.jpg</name>
      <ExtendedData>
        <Data name="url">
          <value>https://commons.wikimedia.org/wiki/File%3AHundeluft%2Ejpg</value>
        </Data>
      </ExtendedData>
      <Point>
        <coordinates>12.34471667, 51.96599722, 0.</coordinates>
      </Point>
    </Placemark>
...

Falls die Datei im Browser angezeigt wird, muss man sie natürlich noch lokal speichern.

I’ve been reflecting on the balance between mapping for ‘volume’ and mapping for ‘precision.’ While I understand the value of quick, large-area edits for global visibility, I find it a bit puzzling when polygons are generalized to the point of overlapping everything in sight—especially when high-resolution imagery is available.

I’ve noticed a trend where edit counts are sometimes treated as the ultimate metric of a mapper’s worth. I reckon we should be careful not to let the pursuit of ‘top contributor’ stats overshadow the primary goal of creating a detailed, accurate map for everyone. For me, a well-traced building or a correctly aligned path is worth far more than a high edit count achieved through imprecise mass-mapping. I’m always keen to learn the best practices, so if there’s a standard way to maintain precision while contributing efficiently, I’m all ears. Cheers.

Desafíos y adaptaciones en la organización de mapatones anticipatorios

En el equipo América Latina de HOT tenemos 4 años organizando mapatones preventivos nacionales en México, Perú, Ecuador y Colombia. Estos mapatones responden al 100% a una necesidad de los gobiernos locales y organizaciones dedicadas a la preparación y respuesta ante desastres. La organización de dichos mapatones entonces definen áreas específicas de máxima exposición a desastres en lugares donde llegan estos a ser conocidos porque son recurrentes. Nos lleva a concentrarnos en la categoría de los desastres climáticos. Esto también define en buena parte la temporada en la que deben suceder los mapatones para proceder datos de forma anticipada, no después de que haya pasado.

Otra característica que define la temporalidad de estos mapatones es cuando la población que más participa en las actividades se encuentra con disponibilidad. El conjunto de estos dos factores es lo que define (de manera imperfecta) los periodos de estos mapatones anticipatorios.

Waiting for someone to do Portland on OHM. About 90% of the people reading this will go “What is Open Historical Map!?”. It’s sadly never used… I wish it was updated more often…

State of the Map US 2026 Presented by OpenStreetMap US was this weekend in Madison, Wisconsin. As any good breakfast lover, I tried to seek out the best breakfast food in the area of Capitol Square. Here’s my thoughts:

Friday: Wonderstate Coffee (on OSM)

This is a very modern looking coffee shop (think crisp whites and light woods - if Apple had a coffee shop) with a great seating area outside overlooking the Capitol Square and is in a very nice spot to be shaded in the morning to enjoy your coffee or small food item. Only downside to sitting outside is you are very close to the road - but that’s to be expected in a downtown area.

I ordered a plain bagel and cream cheese, and an iced coffee with cream and sugar. Typically where I am this means drip coffee poured over ice, but the barista recommended an Americano… when in Rome I suppose. The coffee was delicious, and the bagel came out with more cream cheese than I think I have ever seen on a bagel (not complaining! Just surprising!)

Cost: $9.23 Rating: 7/10

Saturday: Marigold Kitchen (on OSM)

Such a cute spot! I was searching this day for a good omelette and this place seemed highly recommended. The feel was much more artsy coffeehouse vibe, plenty of lighting and a small outdoor seating area, but I ate inside. I was greeted and handed a menu at the door, ordered at the counter, and was recommended the pancakes as well as the omelette if I was hungry enough. Very friendly staff throughout even during what was clearly an elevated breakfast rush with the farmers market getting started just outside!

Hallo zusammen, nach meiner Ansicht wäre es sinnvoll ein Symbol für einen AED zu erstellen. Dann könnte man auch die Standorte von diesen Geräten in den Karten einpflegen. Die Abkürzung AED steht für Automatisierter Externer Defibrillator (oft auch als „Laien-Defi“ oder „Herzstarter“ bezeichnet). Es handelt sich um ein kleines, tragbares medizinisches Gerät, das bei einem plötzlichen Herzstillstand durch gezielte Stromstöße lebensgefährliche Herzrhythmusstörungen beenden kann. Diese Geräte sind wichtig für Ersthelfer die bereits eine Reanimation durchführen bevor der Rettungsdienst eintrifft. Ein Symbol wäre zum Beispiel wie in meinem Link vorgeschlagen eine gute Idee. https://shop.murer-feuerschutz.de/images/thumbs/0028576_241717.jpeg Ich würde mich freuen, wenn man dies umsetzen könnte. Mit freundlichen Grüßen D. Weinig

Hi again!

In my previous diary entry I introduced myself and my GSoC project with Valhalla, and I mentioned we were still putting the finishing touches on the exact main goal. Now we have it! We’re focusing on area routing. This is basically means making the router cross open pedestrian areas (like squares) instead of walking around them and generating weird and inefficient routes. This diary entry is a deep dive into the research I’ve done while exploring the different options.

The problem with pedestrian areas

When you ask a router to go across a square, you would expect it to cross it like any person would. But a lot of routers don’t do that, they may send you around the perimeter or go along the streets surrounding the square. The problem here is that the open area has no “ways” inside of it to travel on.

Let’s see one example (using Valhalla) on Plaza Santo Domingo in Murcia (my hometown!):
