The project goes slowly. Surely but slowly. I wish it were my day job. I have had to give up several other projects for lack of time.
After Christmas I hope to release the first two parts, the equivalent of the 1:40k maps at McMasters Library (51b and 51a) which covers Arras, Douai, Valenciennes, Quesnoy, Cambrai and Croiselles, featuring identified WW1 airfields, roads, tracks, railways, canals, rivers, forests and towns. This morning I finished a tricky irrigation area around Torquenne, roughly sw of Douai. I am moving slowly west towards the trenches and Arras beyond.
Happily, Guise falls within the limits of my project

and again I am indebted to you. I have almost completed the area from Dunkerque to Nieuport to Ballieul and St Omer with your Les Moeres overlay, which I had so much trouble locating.
If all goes well I will upload the first release at SOH when its done and I'll be sure to make mention of it here.
Cheers Grinseed
