[HOT] HOT #2398 concern about old imagery date

[Martin Hibbert]

I'm doing validation on HOT #2398 (Aweil, South Sudan).

Following discussion with a mapper (Task 1789 
<http://tasks.hotosm.org/project/2398#task/1789>) I have checked the 
date on the Bing imagery and found that to the west of Aweil (and thus 
most of #2398) the imagery is dated '3/30/2010-1/7/2011', as reported by 
JOSM Tile Info.

My concern is that this is before South Sudan became a separate country. 
Civil war and huge displacement of peoples means that the situation on 
the ground will have changed radically.

If you look at Google Maps imagery (presumably of a later date) you can 
see there are changes.

I've attempted to contact the project manager to discuss, but given that 
it is New Year weekend cannot realistically expect a response until next 
week.

Mapping using out of date imagery seems such a waste of hundreds of 
hours of volunteer time, although it is obviously for MSF to decide if 
the resulting data is useful.

Does anyone share my concerns? Is there anyone else from MSF on this 
list who could give a view?

Thanks

Martin
