Up next, a couple more requested maps - A beautiful Spanish metropolis, and the "Rose City"
Also - this is quite an interesting comparison - One metro being nearly 3 times as big as the other in population, but the smaller of the two using more land
Madrid, Spain

note: Madrid seems to have a lot of under construction areas (clearly white on the map) - I have mostly left these unshaded but some of them may be finished projects etc
Portland, OR
