I have found a source for the strength of the luftwaffe and where it was deployed
here
Before I spend forever cross refferencing what aircraft are at what airfield has anybody already done that?
If not would it be worth my posting it once I have done it??
It is one of the sources i use in WWIIg project on sourceforge.
I do not currently have a georeferenced timeslice for May 1940 though, and likely it mean you need to create it yourself.
My current timeslice format is CSV. With geo-referencing in machine-readable format as i did it is easy to do cross-referencing.
WWIIg data are mostly in wardata/mapobjects.csv and wardata/unitsdb2.csv and referencing to weapons database wardata/weaponsout3o.csv2
Will be very happy if you have interest to create such formalized timeslice for May 1940. Need really sustained effort though, due to sheer amount of data (timeslice of June 1941 is about 4MB of text despite of being incomplete).
