A bit choppy because of the basically nonexistent GPU, and I just made it with xdotool (moving the mouse straight/consistently) while recording the screen, but I'm quite impressed with the level of detail of this 3d map!

#12Awesome. Breathtaking. But the imagery isn't from satellite data, is it? Must be from airplanes.
The point clouds from those height maps alone, though, I already find to be quite interesting/revealing. You can see the contours of e.g. a tree exactly, even without having any imagery laid onto them: https://snipboard.io/tPsRBo.jpg

#14Nice! (Note: It takes forever to load, but it's worth the wait.) The not yet loaded tiles give a interesting "thirteen floor" effect :) I found a glitch https://imgur.com/a/6Oh3AQn https://en.mapy.cz/zakladni?m3d=1&height=1100&yaw=234&pitch=... It looks like a quarry. Is the wall too vertical just in the border between tiles? Did they dug that part just between photos?

#17Why don't map sites ever publish 3D as topo lines overlaid on a flat 2D map? It's computationally much cheaper, and it's not too hard to learn to read a topo map, as long as the elevations are printed in a reasonably dense manner.

Why sacrifice accessibility and usability to save on a bit of computation?
