I'll be visiting Botswana and Namibia this summer. We plan to rent a vehicle and make our way from Livingstone south through Botswana and then west through Windhoek to the Namib Desert. Can anyone recommend a good up-to-date road atlas or travel guide that covers this area?

I see that Lonely Planet and Globetrotter have atlases available, has anyone used these recently?

thanks.
