Neuer Server für die Geofabrik

27.01.2016 | Philip Beelmann

Im Dezember trafen in der Geofabrik – so wie es sich für die Weihnachtszeit gehört – nach und nach allerlei Pakete mit Hardware ein. Zu meiner Freude durfte ich die Komponenten zu unserem neuen Flaggschiff-Server zusammenbauen, der pünktlich zum Jahreswechsel in Betrieb ging.

Dank zweier Xeon E5-2623 v3 Prozessoren, 8x 32GB Arbeitsspeicher sowie 26 TB Festplattenspeicher sind wir auch für das weitere Wachstum der OSM-Daten gut gerüstet. Und das 1000-Watt-Netzteil hat auch noch ein bisschen Reserve für künftige Upgrades…

Die OSM-Nachtlebenkarte

21.09.2015 | Frederik Ramm

Im Juli hat eine Studentin der Hochschule Karlsruhe, Lisa Stolz, bei der Geofabrik ihre Bachelor-Arbeit abgeschlossen. Lisa studierte Kartographie und Geomatik, und da bot sich ein gestalterisches Thema an – die “Nachtlebenkarte”.


Es gab ja schon einige Karten in dunklerem Stil oder den Versuch einer “Lichtkarte”, aber was Lisa versuchen wollte, war, diejenigen Orte, bei denen man anhand von OSM-Daten auf das Vorhandensein eines gewissen Nachtlebens schließen konnte, durch hellere und buntere Farben auch auf der Karte lebendig werden zu lassen. Dabei wurde z.B. auch von der “Kneipendichte” auf die Belebtheit einer Straße geschlossen, was sich dann in einem helleren Farbton äußerte.

Die Bachelor-Arbeit steht als PDF-Datei zur Verfügung, und der Stil kann auf GitHub unter einer freien Lizenz heruntergeladen oder abgeändert werden. Für eine begrenzte Zeit steht auch eine weltweite Demo-Ansicht zur Verfügung.

A new, world-wide water and waterway debug layer is live at the OSM Inspector web site. We’ve done away with the old VMAP0 river reference, and extended coverage from Europe-only to the whole planet.


There’s tons of new features – for example, OSMI will detect when a river changes its name, or starts out of nowhere (or ends in something that is not another body of water).


Rivers without names are highlighted, as are directional problems where two parts of a river flow towards, or away from, the same point.


The software backing these new layers has been written in C++ (using Jochen Topf’s excellent Osmium library) by Geofabrik intern Nathanael Lang. It is Free Software, and can be run in a standalone fashion to convert an OSM .pbf file into a SQLite database if you’d like to run your own analyses. Fork it, or report issues, on GitHub!

OSM Inspector Address View now world-wide

11.04.2014 | Frederik Ramm

For over 5 years now, Geofabrik’s OSM Inspector is an important quality assurance tool for OpenStreetMap, used by thousands of mappers on a daily basis to check their local area or their own work.

Some of the Inspector’s layers, like for example the routing problem analysis or the broken multipolygon view, have already been available world-wide for a while; but others were restricted to Europe because of limited resources.

Today we announce the launch of a world-wide address layer, highlighting mistyped addresses, addresses without matching roads, bad interpolation ranges, and other common problems with addresses in OpenStreetMap. The new view is available from the standard view select drop-down in OSM Inspector, replacing the previous Europe-only layer.

This view was previously computed by a relatively slow process based on a PostGIS backend, and now uses a completely new standalone backend that is based on Jochen Topf’s new Osmium library, and available on GitHub.

This launch is made possible by a generous hardware sponsorship from Canadian telematics company Geotab Inc. – thank you!

We’d also like to thank Lukas Toggenburger, who developed the new OSMI address backend as part of a project thesis for his master studies at HTW Chur, in Switzerland, in a cooperation with HSR Rapperswil.

The OpenStreetMap Foundation is an English non-profit organisation created to support the OpenStreetMap project. It has about 500 individual members. The Foundation pays for the servers on which OSM is run, organises the yearly “State of the Map” conference, and last not least also has to deal with the legal aspects of running a world-wide, crowd-sourced mapping project. Foundation work is done by volunteers entirely (one of which is this author), but of course money is needed for hardware and hosting, accounting, legal fees, and various bits and pieces that help the volunteers do their jobs.

Since the Foundation’s last Annual General Meeting in September 2013, the Foundation is open to corporate members.

You can now be among the first who publicly show their support for the OpenStreetMap project by signing up as a corporate OSMF member. The membership fee is £1,000 per year (at current rates, that’s €1,200 and US$1,650). Your membership fees will help to keep OpenStreetMap’s servers running and ensure the continued success of the project.

Geofabrik, of course, has joined already, and we encourage our friends and clients to do likewise.
