Cities as measures — Wasserstein distances (?)
The sphere distance compares street-direction measures on ℝP² modulo rotation about the vertical axis — grids match however they are oriented. MDS embeds the distance matrix into 2D: nearby points are similarly-built cities.

similar cities; click a row label or MDS point to open the city.

Overlay cities
Select up to 3 cities to superimpose their bearing roses and elevation-angle distributions.
