Before GPS, it was mostly the topology that mattered to motorists, but the military probably wanted accurate coordinates on everything.

True! Of course topology includes getting the petrol station on the right side of the road.
I even heard of some maps with a 'sliding scale' that eg has the city centre larger. You can't even do that on a flat piece of paper without serious distortions in your coordinates.
