Thank you for your additional comments and questions, Andy and Alan.
We do not have GPS traces for these countries. Instead, our engineers make extensive use of Bing and Digital Globe imagery to validate the leads.
Our editors use Maxar, Esri and Bing imagery to verify the roads they are creating.
If you have any further questions or comments, just let me know.
