I always found these very intuitive, but I don't know if that's just due to having an analytical mind, or just learning this stuff early. Do people struggle to understand topographic maps?
It gives a basic idea, but I think something like Cities:Skylines where you can create maps using a height map and then get the topography lines in a 3d space where you can actively shift the camera around to see them overlaid from any angle would probably help people grasp the idea.
Having said that, I'm now imagining drone footage overlaid with the height maps as an additional resource to standard topographical maps. Would be neat if somebody could create software that could calculate and overlay the height maps in real-time using the drone's altimeter or something.
In the Land Nav portion of PLDC (US Army training for becoming a Sergeant - is called something else now) there were soooooo many people that failed out/had to do it over again, that I was super worried when I did it. Seemed pretty damn easy to me. 🤷
I’ve always been curious about topographical maps that involve curved or hanging terrain and whether there’s a way to denote the existence of an area beneath. That’s obviously going to be irrelevant 99.9% of the time, but grade school curiosity rarely fades completely.
Also it helps to look at water on the map. Water always runs downhill. Runs combine to form creeks, creeks combine to form rivers, rivers pour into oceans and lakes. Water gets bigger on its way downhill. The dead end is a spring, it flows downhill from there
Depends on the rest of the map. These are usually set up so the rings mean a certain consistent difference in elevation, say 1ft of 10ft. You don't normally change the spacing partway through the map. If the intervals were 10ft and this was a 20ft peak then you'd obviously have fewer rings than if the intervals were 1ft.
The rings are elevation placements. Less would be "correct in that they'd still signify elevations, it's just less detailed.
For example, the widest ring might be an elevation of 2470ft while the smallest ring might be 2570ft. If there are no rings in between, it's still correct, you're just not getting very detailed. You could easily be looking at a perfect sloap on all sides, like a smooth cone. But place 9 rings in between at 10ft more of elevation each, you've got a much more detailed idea of how a mountain or hill is shaped.
