Personally, this is the solution I'd like to see:
You know how you can select different maps to view on the clipboard? I'd like a flag in the config file showing which of those you'd like a position icon on. That way you could have different versions of a terrains map for different purposes. A flat, zone tinted version that doesn't show elevations but where you can see dar icons against very well. Then switchover and see a fairly detaiiled elevation map with gradation lines with enough detail to plan GV operation and find low spots for reverse slope defensive positions. How to get from A to Z with climbing the least number of hills, etc. The maps could be of different resolution. The flat paper map to see dar icons doesn't need a lot of res. So maybe its 512x512 pixels. The GV terrain elevation map needs the most resolutions to show fine scale ground detail. 2048x2048 pixels? Anyway, my point being, I don't think a single style map can serve all the needs to maximium effeciency.
