Yes of course, and I have no insight into how they worked with maps (except remote imaging), I just know that the amount of hours you need to invest per village with 300+ pop is quite large. There are also several organizational issue with maps, how do you keep them secret, what do you map, where do you map, if caught with a map are you a spy. Basically why would you give a beat cop a top secret map, my comment about Openstreetmap was a joke but it highlights the bigger problem that maps are a social good and that is not always the goal of the intelligence community in hostile environment.
