From OpenStreetMap to Power BI: Visualizing Wild Swimming Locations

A detailed process is outlined for creating an interactive map of wild swimming locations using data from OpenStreetMap (OSM). The method involves using the Overpass API and its query language, Overpass QL, to extract specific geographic points. It explains how to build a query to find features tagged with `leisure=bathing_place` or `leisure=swimming_area` within a defined region like Spain and Portugal. The retrieved data, including coordinates and descriptive tags, is then intended to be imported into Power BI for visualization.
