>Greenland looks to me like a series of concentric hills.
What you are looking at is an implicit contour map - normally these lines are drawn in post processing to highlight levels of constant elevation. If you follow the "concentric hills" you are staying level and going around the hill. If you move perpendicular to them you are going straight up the slope in the direction of the gradient.
- rendall 5y agoYes. Sorry, I wasn't clear. Intellectually, I understand what's intended, but the visual effect of hills and valleys however is very strong and hard to ignore. I can read and understand that the dark lines on Greenland are isoclines, but having an intuitive feel for what these patterns represent is elusive. The visual idioms of light as height and dark as depth is probably too entrenched for me.
- SamBam 5y agoI agree. It looks like ripples in a pond. But, more importantly, even if I get that it's all increasing, it's impossible to tell if it's rising smoothly or not.
