[OSM-talk-be] Digital Globe Images

[Julien Minet]

Yop,

In Belgique du Sud, I think DG standard imagery is from May-June 2015.
Lastest SPW imagery is April 2015 (I have very good,  changing ground truth
for 2015!).

If remenber well our last OSM meeting in LLN, we haerd that SPW will
release 2016 or 2017 imagery soon.
