Let's play with Brno Data
summary
Brno Open Data portal provides many municipal datasets but most are messy: about 60–70% meet three-star openness (CSV), ~20–25% are two-star, and none reach four or five stars. Shape files often aren’t published, column names are full sentences, files are needlessly split, and most metadata is Czech-only. Analysis uses R notebooks, Jenks natural breaks, quantile filtering, and spatial viewers like Kepler.gl and Leaflet; crime data shows outliers (one damage entry ~12.5M CZK) while typical incidents are ≤25,000 CZK.
