@heigit did a great comparison of OSM land use data with an external dataset. But I have a gripe with how they present OSM as the inferior dataset. I blogged about it at https://www.openstreetmap.org/user/tordans/diary/407524
Authoritative Data is Not More Right Just Because It’s Authoritative
HeiGIT recently published an analysis together with the German Federal Agency for Cartography and Geodesy (BKG), comparing land cover data from OSM with the official CORINE Land Cover (CLC) dataset from BKG.

Looking for a nice trip location around Berlin: There are those open (private) Garden events in Berlin+Brandenburg every month. I was annoyed with their official website having no map+date filter, so I build this to help find a nice garden to visit: https://tordans.github.io/offene-gaerten-karte/

Off all the new NLnet Fundings (NGI0) only one is directly OSM related and off all the things that could be funded it had to be the one that from my point of view does not benefit the project at all but is either time spend unwisely or a future escalation waiting to happen: OSM-NG, a one person […]

There is some movement in the #OSM-Centerline-Processing space recently. This is one of the issues that we need to solve to make OSM data suitable for analysis and planning purposes, so it is great to see research and prototypes in this space. Dustin from osm2streets has this great list of […]

Today I learned that Mapillary/Facebook no longer uses the #OpenStreetMap Buildings in their OSM-based map, having switched to the Overture Buildings Dataset. Someone noticed this change in a place in Germany where the buildings differ between the maps.

#OpenStreetMap: I was wondering what an OSMCha Frontend would look like with a modern tech stack. So I took some time during my vacation to find out: https://github.com/tordans/osmcha2/issues/1. Anyone good at NextJS and eager to use a fresh OSMCha frontend? Maybe we can finish this over time…
