Mozilla just published a new map showing the growing coverage of Mozilla Location Services. Mozilla announced Location Services late last year as a pilot project to provide geolocation lookups based on cell tower and WiFi access point information. These geolocation lookups can be used where GPS is not available or not accurate enough. The map shows 27 million measurement locations gridded to 10x10 meter cells. Working with Mozilla’s team we created a dark variation of Mozilla’s custom branded Mapbox maps, and rendered out the high density data using datamaps down to zoom level 15.
