OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. OSM is considered a prominent example of volunteered geographic information (VGI) or crowdsourcing. There are several ways to use the data:
- Through the interactive map on the OpenStreetMap website (http://www.openstreetmap.org)
- In QGIS you can add OSM basemaps via the QuickMapServices plugin
- In QGIS you can download OSM data directly over the Internet. There are several ways to do this. In this section we’ll use the QuickOSM plugin which uses the Overpass API.
In this tutorial we are going to download OSM vector data for the area of your interest.
