Engineering Working Group

Posted by drolbr on 4 October 2021 in English.

While the heart of OpenStreetMap is the community of mappers, it has also a remarkable ecosystem of software developed and used for OpenStreetMap. Many people are surprised to learn that it is so federated that the OpenStreetMap Foundation does only a tiny part of it.

The key to understand that is that many software projects have developers out of personal passion. The long time editing tool Potlatch has been developed and kept alive by Richard Fairhurst, JOSM luckily has a whole team behind it, and also Vespucci, OSMAnd, Nominatim and Osmium each are closely tied to names, as well as many other tools. This both keeps each of the tools focused and gives them a direction. Large organizations cannot offer that, because more often than not the managerial fashion of the season will interfere with pursuing long term goals.

Nonetheless, outsiders that expect a single point of contact shall have one. This is where the idea of the Engineering Working Group comes into play: it has a more specific mission than the board in general, but it still can send people and inquiries to the right places.

The EWG does not replace issue trackers. The EWG is not the right venue for comprehensive visions of the future. But it shall help to improve the flow of information related to development of OpenStreetMap related software.

I’m happy to chair the just restarted EWG.

Zahl des Monats: 74.9 Prozent

Posted by drolbr on 20 October 2016 in German (Deutsch).

Vorab das Wichtigste: Die neue Version 0.7.53 ist auf overpass-api.de und dev.overpass-api.de jetzt aktiv. Die Rambler-Instanz wird in den nächsten Tagen folgen.

Weitere Details dazu werde ich weiter unten geben, ebenso, warum ein Vorfall rund um Pokemon Go mein Weltbild zu Zugriffsregeln erschüttert hat.

Doch zunächst möchte ich die Zahl des Monats präsentieren: 74.9 Prozent. Von 74.9 Prozent aller IPv4 /24-Subnetze, also aller überhaupt möglichen solchen Subnetze weltweit, habe ich mittlerweile Zugriffe in den Logfiles gefunden. Zu diesen Netzen gehören z.B. die von General Motors, Ford, Toyota, Daimler, BMW und Volkswagen. Bei Medienhäusern z.B. New York Times, Guardian und Der Spiegel. Weiterhin: SNCF, Deutsche Bahn, SBB, zahlreiche Universitäten und sogar ESRI. Selbstverständlich auch eine lange Liste von gewöhnlichen Internet-Providern. Zur Erinnerung: die Overpass API liegt eher im Maschinenraum und ist mehr technisch als nutzerfreundlich. Daher dürfte die amortisierte Reichweite der diversen Tile-Server noch weitaus höher liegen. Das passt sehr gut zu der Beobachtung, dass große Teile der öffentlichen Verwaltung in Deutschland damit experimentieren, OpenStreetMap in ihre Arbeitsabläufe zu integrieren.

Fazit: OpenStreetMap ist alles andere als klein. Es ist bereits der De-Facto-Standard für Geodaten. Und wenn es Wachstumsgrenzen für OpenStreetMap gibt, dann ist die Wichtigste davon die Größe der Menschheit.

Das heißt nicht, dass eine Mehrheit der Menschheit bereits OpenStreetMap nutzt. Geodaten kann man nicht essen, sie sind auch kein Medikament. Geodaten sind wichtig, aber nicht der Schwerpunkt der Welt. Die Statistik von oben sagt also: Wer sich für Geodaten interessiert, der kennt höchstwahrscheinlich OpenStreetMap.

The number of the month: 74.9 percent

Posted by drolbr on 20 October 2016 in English. Last updated on 21 October 2016.

The most important news is that version 0.7.53 is now live on the dev.overpass-api.de and overpass-api.de server. The Rambler server will follow in the next days.

I will give details on this further below. Also below I will explain how an incident with Pokemon Go shaked my mindset about quota policies.

Before this I will present the number of the month: 74.9 percent. From 74.9 percent of the total IPv4 /24 subnets of the entire world I have observed requests in the logfiles. Amongst some random IP block owners from the logfile: General Motors, Ford, Toyota, Daimler, BMW, Volkswagen. Media Outlets: New York Times, Guardian, Der Spiegel. Further starring: SNCF, Deutsche Bahn, SBB, numerous universities and even ESRI. Of course also long lists of telephone carriers. Remember that Overpass API is a quite deeply buried and highly technical service. It is almost sure that the popularity for the combined tile servers is even higher. This matches very good with the observation that half of the public administration in Germany is figuring out how to get OpenStreetMap in their workflow.

Punchline: OpenStreetMap is by no means small. It is the de-facto standard for general purpose geodata. And if there are limits to the growth of OpenStreetMap in sight, then these are most likley the size of mankind.

This does not mean that the majority of mankind is using OpenStreetMap. Please do not forget that you cannot eat geodata. Or substitute drugs. Geodata is in important field, but not the core of the world or the internet. The statistics from above say that whoever is involved in geodata is almost surely aware of OpenStreetMap.
