Discovering 40 Geo-APIs in 40 Minutes
summary
Live demos and GitHub code show loading basemaps (Mapbox, Bing, Google, ArcGIS) and building Leaflet visualizations including heatmaps, marker clustering, and 3D extrusions using cadastre heights, plus isochrone (commuting area) generation. The talk compares geocoders by batch-testing Mercadona addresses via Google Sheets and plotting 33 markers to illustrate differences between OpenStreetMap, Google and ArcGIS (with ArcGIS closest in the examples), demonstrates routing engines with elevation for cycling, traffic feeds updated every five minutes, enrichment layers like income per capita, and highlights a corrupted dataset of 200,000 Madrid businesses shifted by about 100 m.
