Great source for street data, and other infrastructure. Global coverage. Download OSM data directly through the map interface or other sources (including Geofabrik and the HOT (Humanitarian OpenStreetMap Team) export tool). OSM data may also be accessed via a QGIS plugin. OSM data is edited and updated by users, so it may be worth validating against current imagery in a GIS program.
