As home to over 1 billion people, Africa is the world’s second most populous continent. As part of our continuing roll out providing global map coverage at the largest scales, Africa is our latest update for the ArcGIS.com basemaps. Detailed coverage of Africa was recently released down to ~1:4k continent-wide and down to ~1:2k and ~1:1k in urban areas. We accomplished this expansion by incorporating OpenStreetMap data for 42 countries into our data model for display in the AGOL basemap cartography. OSM data is now found in the following basemaps: World Street Map, World Topographic Map, Light Gray Canvas Base, and the three reference overlays: Boundaries & Places, Boundaries & Places Alternate, and Transportation. In Ghana, we continue to utilize data contributed through the Community Maps Program. All data used in our basemaps—commercial, community, and OSM data—will be updated periodically.
Visit the map item pages for information on our methodology to process OSM data and attribution, which is provided in support of the share alike provisions of the OSM data license. Dynamic attribution is also provided on the map in various applications, such as the ArcGIS.com map viewer.

Look for additional improvements to the core basemaps throughout the year. Updated data and expanded coverage will appear in areas of North America, Europe, India, and the Asia Pacific region.
