GeoLife GPS track collection processing with DuckDB, QGIS & Trajectools
The last time I preprocessed the whole GeoLife dataset, I loaded it into PostGIS. Today, I want to share a new workflow that creates a (Geo)Parquet file and that is much faster. The dataset (GeoLife) "This GPS trajectory […]

We're back with another Mapping Minds- featuring Chris Darimont🌍
Chris is well known for taking a walk on the wild side and is our go-to-guy for all things bears 🐻🐾
If it were up to Chris, he'd be suited up chasing waves 🌊on the island's most rugged breaks 🏄♂️
