Direction measure on the sphere
Each tile is a (bearing × grade) bin; band spans grades 0–50%
(why?). Antipodal tiles mirrored; ring = flat (equator).
Unrolled: bearing × grade heatmap
the same measure flattened — rows are grade bands (top band = ≥ cap).
Bearing measure (projected to the circle)
marginal over grade — Boeing's rose, 180°-symmetric (?).
Hill fan — street inclination rose
the elevation-angle measure drawn at its true angle from horizontal
0% grade lies flat (horizontal); steeper grades fan up at ×3 exaggeration, ticked by grade %; radius peak-normalized
(?).
Grade distribution (log)
the fan unrolled: share of street length by grade %, log y — small
differences among flat cities show as vertical offsets.
Street character
full breakdown, colored per attribute: lane counts, sidewalk & cycleway
provision (among tagged roads), and transit-lane / alley share (of all length).
Most similar cities
nearest by each Wasserstein distance (?).
Analyzed region
What this analysis covers
shaded cells = the density-derived urban core actually analyzed
(for boundary-extent cities this is the city limits minus low-density areas);
ring = fetch disc (disc-extent cities only); small circles = neighborhoods.
