[HOT] Central African Republic import of WRI data

[Severin MENARD]

Hi,

I agree with Andrew regarding the importance of creating a connected road
network. Actually I already mapped a lot the roads with Bing Imagery and
some sections are not covered by high res imagery but sometimes the LandSat
medium res allows to identify the roads. In these cases I traced it and
informed about the bad accuracy in a fixme.

Sincerely,

Severin
