Dask-GeoPandas vs PostGIS vs GPU: Performance and Spatial Joins

Paul Ramsey saw a spatial join done using a GPU and tried to do the same with PostGIS, checking how fast that is compared to the GPU-based RAPIDS.AI solution. Since Paul used parallelisation in PostGIS, I got curious how fast Dask-GeoPandas is on the same task. So, I gave it a go. Let’s download the… Continue reading Dask-GeoPandas vs PostGIS vs GPU: Performance and Spatial Joins

Methodological Foundation of a Numerical Taxonomy of Urban Form

The final paper based on my PhD thesis is (finally!) out in the Environment and Planning B: Urban Analytics and City Science. We looked into ways of identifying patterns of urban form and came up with the Methodological foundation of a numerical taxonomy of urban form. You can read it on the journal website (open… Continue reading Methodological Foundation of a Numerical Taxonomy of Urban Form
