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!):

Dieser Monat war extrem stressig für mich und ich muss pendeln und kann daher nicht zum Stammtisch. Nächstes Mal bin ich aber wieder dabei. Viel Spaß an alle die zum Stammtisch gehen.

Please help me raise funds to purchase the missing sheets from the complete historical 1:50,000 topographic map series of Zimbabwe, formerly Rhodesia.

https://gofund.me/f12d5f3d2

Donate and more information at https://www.gofundme.com/f/purchase-historical-zimbabwe-topographic-maps

Previous donation drives:

• Namibia (South West Africa) - 2008 - https://namibia-topo.openstreetmap.org.za/
• Eswatini (Swaziland): - 2015 - https://eswatini-topo.openstreetmap.org.za/

In the unlikely event that any funds remain after purchasing the Zimbabwe map sheets, they will be used to buy missing sheets from the Lesotho or Malawi 1:50,000 topographic map series, which are planned as future projects.

If you use the amazing better-osm-org browser extension/userscript to review changesets, you are probably familiar with its default red, green, and yellow diff highlighting.

While the default colors are great, sometimes you want a custom color scheme that feels more comfortable for your eyes during long validation sessions. For instance, changing the added tags to a cool cyan, keeping deleted tags red, and making modified tags a soft cream/yellow.

Since the script dynamically manages light/dark themes, the easiest way to override these colors globally without messing up the extension’s code is by using custom CSS via the Stylus extension.

How to Apply It:

1. Install the Stylus extension (Chrome/Firefox/Edge).
2. Go to openstreetmap.org.
3. Click the Stylus extension icon and select ”(+) Write style for: openstreetmap.org”.
4. Paste the CSS code below into the editor, give it a name (e.g., Better OSM Custom Colors), and hit Save.

The CSS Code:

/* 1. MODIFIED TAGS -> SOFT CREAM / YELLOW */
    tr.quick-look-modified-tag th,
    tr.quick-look-modified-tag td {
        background: rgba(255, 235, 150, 0.7) !important;
        color: #000000 !important;
    }

/* 2. DELETED TAGS -> RED */
    tr.quick-look-deleted-tag th,
    tr.quick-look-deleted-tag td {
        background: rgba(238, 51, 9, 0.6) !important;
        color: #000000 !important;
    }

/* 3. NEW TAGS -> CYAN */
    tr.quick-look-new-tag th,
    tr.quick-look-new-tag td,
    tr.quick-look-added-tag th,
    tr.quick-look-added-tag td {
        background: rgba(0, 200, 220, 0.6) !important;
        color: #000000 !important;
    }

As I had mentioned in my last post where I explain what they are, I had long planned to make a video about mapping historic lifting stones. It took a while to get to sites and some footage etc and to figure out how to map them best, at least in my opinion, but the video is now online on Youtube. I’ve added subtitles in English, German, Irish, Basque, Finnish, Icelandic and Welsh, because these are to my knowledge the countries where the tradition is still upheld or has been revived. For everything but German, I used the auto-translate function, but YouTube tends to not know the correct word for “lifting stone” in the respective languages, so if anyone can correct me on the subtitles, I’d be grateful. For the same reason, I did not translate the title of the videos into most of these languages, and also because I didn’t want to give the impression that it was completely available in these languages. It is possible now, I think, to have the audio generated in other languages, but that is too creepy to me. As curious as I am to hear myself speak fluent Welsh, I’ll give it a pass.

I’m hoping to do another shorter video about mapping them using OSMAnd, but I need to get to a site of an unmapped stone first which is easier said than done, considering I don’t drive and there are not that many unmapped ones near me. The sites in the current video were accessible by public transport, walking and cycling, so it’s a very sustainable video in its production.

I’ve also done a bit more work on the English wiki page for historic=lifting_stone, translated it into German and written a wiki page for leisure=lifting_stone. The latter is for the newly placed stones and the historic ones that are being lifted again.

I would appreciate if people capable of the above languages could translate the wiki pages into those languages to get a wider coverage of them being mapped.

En menos de un mes, en Colombia vamos a organizar el primer State of the Map. Este evento conmemora muchas cosas: primero, que la comunidad OSM Colombia es capaz de hacer un evento de marca internacional; segundo, que tenemos una entidad formalmente organizada para representar la comunidad la cual es la Asociación de Cartografía Colaborativa de Colombia - AC3; tercero, que dicha Asociación es oficialmente un capítulo de la fundación OpenStreetMap mundial, para representar a OSM en Colombia.

Como parte de la organización que estamos haciendo, queremos invitar a muchas personas que estén interesadas en el mapa para que nos reunamos por motivo de este evento, ya que no son solo charlas de OSM, sino también es unir a la comunidad, compartir, conocerlos. Entre las cosas que queremos, es proponer un punto de encuentro para todos esos mapeadores de OSM, y no solo los usuarios actuales sino que también queremos invitar a esos usuarios que contribuyeron mucho en el pasado, y que de pronto ya no están tan interesados en el proyecto, pero de pronto, al ver a la comunidad unida, se vuelven a interesar.

Para esto no encontré una utilidad en Internet disponible. Como ya lo mencioné entre líneas, la de Neis Pascal es solo para los usuarios que han contribuido en los últimos 60 días, pero queríamos tener la lista de los usuarios que han apoyado al mapa de Colombia desde su origen. Entonces, por medio del IDE Cursor y con un par de buenos prompts de AI, me generó este proyecto: https://github.com/angoca/topOSMcontributors.

Después de descargar el archivo de GeoFrabrik que es con el que se puede hacer la magia, se procesaron todo el histórico de Colombia y pude obtener los 500 usuarios que más han contribuido en Colombia.
