Jeez,Bob-
I never did get over that way, but from all the maps I've seen of the AO, that's the most detailed, and it looks SPOT ON, as the Brits and Aussies say.
My secondary MOS for many years was cartography,
I did Fld Arty OCS for 16 weeks, (maps, maps MAPS !!!) worked topo survey on the ground for almost two years, and golly- I think mebbe you ought ask an AVIATOR, not me....
