140,000 Miles of African Roads Added to Open Street Map

140,000マイルのデータ量もさることながら、アフリカへの貢献という意味が素晴らしいと思います。

The Open Street Map community has been wonderful throughout the project. Special thanks to Mikel Maron for his extremely helpful advice and encouragement in the early days of our work. We’ve received numerous emails expressing support and willingness to volunteer since we first announced the creation of the team. Now that we’ve got our feet under us, we plan to take a few folks up on these offers and will be coordinating future work on the project page of each country in the OSM Wiki.

日本国内も含めて、いろんな示唆を含んだ内容だと思います。
