OpenStreetMap (http://www.openstreetmap.org) is built by an open community of mappers who contribute and maintain geospatial data. This means that even you and I can get involved if we want to! This data is openly available to the public as long as you provide credit to OpenStreetMap and its contributors.
In earlier recipes, we only took a look at the standard layer type from OpenStreetMap, but there are many, many more layer styles that have been created on top of the OpenStreetMap data. We will show you three different OpenStreetMap sources: Humanitarian OSM, MapQuest Open, and Transport Dark OSM.
