Adding the Missing Dimension: Position Tracking for Vehicle Data Logging
In one of my previous blog posts, I explored how to read live vehicle data through the OBD II port that is present in most (modern) cars. As mentioned in the outlook, the next step in my project is to combine vehicle telemetry with (accurate) positional information in order to enable more advanced analysis. To…

Yes, the Hype Is Real: Building a Local AI Assistant with OpenClaw
Starting point: A colleague asked me on Friday morning: “Do you know OpenClaw?” After about ten minutes of internet research, everything was clear again and my weekend was at least partly gone. “Total escalation” on my side. What is OpenClaw? After Clawd and Moltbot, now OpenClaw. In short, OpenClaw is an open source framework for…

What’s your car really doing? Getting real time data and insights
Some people are curious about how healthy their car really is, while others take their vehicles onto the racetrack where it is essential to avoid overheating or pushing components far beyond their comfort zone. You can, of course, buy small aftermarket performance data displays that many cars support, but some friends would rather save the…

From Sky to Trail: Testing GPS Accuracy with Drones, Action Cam and Smartwatch
In the early days of mapping and cartography experiments, GPS tracks were often the starting point. Contributors to the OpenStreetMap (OSM) project, especially before 2010, relied heavily on GPS devices. They would walk or cycle routes and later upload their recorded tracks and observations to OSM. Today, GNSS-capable devices are everywhere: smartphones, smartwatches, action cams,…

Building My Own Garmin™ Maps for Outdoor Activities Based on OpenStreetMap Data
For many years, I’ve used pre-made Garmin maps from the internet on my devices while hiking, running, or mountain biking. These maps have always been based on data from the OpenStreetMap (OSM) project. In the early days, a map of Europe was just a few hundred megabytes in size and usually fit comfortably on the…

Zwischen Wissenschaft und Kriminalität: Geldautomatensprengungen in Rheinland-Pfalz & Hessen
In den vergangenen Jahren kommt es in der gesamten Bundesrepublik Deutschland immer wieder zu Geldautomatensprengungen. Das Bundeskriminalamt veröffentlicht hierzu jährlich ein Bundeslagebild, das sowohl deskriptive Statistiken als auch weitere Informationen zu den Vorfällen in den einzelnen Bundesländern bietet. Auch in meiner Heimatgemeinde Hünstetten wurde bereits mehrfach ein Geldautomat gesprengt und ausgeräumt. Für mich persönlich war…

Unmapped Places of the OpenStreetMap World – 2024
In 2010, I first conducted a study which identified regions (places) in the OpenStreetMap (OSM) project in Germany that still had potential for more detailed mapping. Later, in 2016, this analysis was repeated and extended to the entire world. I have since regularly carried out these studies and published the results. The algorithm and some…

Wait, someone did what?
Exploring Reverted Map Edits in OpenStreetMapThe OpenStreetMap (OSM) project has over 10 million registered members, with around 2 million user profiles having made at least one map contribution. However, a closer look reveals that there has been a slight decline in the number of active contributors over the last three years. Despite the extensive global mapping community, there are instances…
