Green-blue Space Analysis

City-Level χ-Expectation

LEGEND

More Green (χ-exp > 0.73)
As Expected (-3.61 ≤ χ-exp ≤ 0.73)
Less Green (χ-exp < -3.61)

STATISTICS

Total Cities: 184 Total Photos: 94433 Green Photos: 30749 Global Green Ratio: 32.6%

Classification Method:
Based on 33rd and 67th percentiles of χ-expectation values across all cities.

Circle Size:
Radius is proportional to |χ-expectation| value. Larger circles indicate greater deviation from expected green space ratio (either more or less).
