Reading these numbers
What is actually being measured
Tree cover
The share of ground under canopy inside a 2 km radius of each city centre, read from Sentinel-2 satellite imagery at 10 m detail. It is a measurement of that circle, not of the whole municipality — which is exactly what makes the two comparable, since city boundaries are drawn to wildly different rules around the world. Gasteiz / Vitoria leads here at 22.4%.
Air quality index
The live US EPA index, computed from current pollutant concentrations — ground stations where a city has them nearby, and a model everywhere else. It moves hour to hour, so this is a snapshot rather than a verdict on either place: Gasteiz / Vitoria reads 53 (moderate) and León reads 38 (good) right now.
Frequently asked
Gasteiz / Vitoria and León, answered
Which has more trees, Gasteiz / Vitoria or León?
Gasteiz / Vitoria, with roughly 70,372 trees inside its 2 km radius against 64,088. Tree cover tells a slightly different story from raw count: Gasteiz / Vitoria has the denser canopy at 22.4%.
Which has better air quality, Gasteiz / Vitoria or León?
León right now, at AQI 38 against 53 — a gap of 15 points. This is a live reading rather than an annual average, so it can reverse within a day.
How many more trees does each city need?
Gasteiz / Vitoria needs about 23,876 more to reach its canopy target, and León about 30,159. The target is the same share of ground for both, so the figures are directly comparable.
Are these two measured the same way?
Yes — that is the point of the page. Identical radius, identical satellite source at 10 m detail, and the same US EPA index for air. Nothing here is adjusted for population, city limits or climate, so the numbers describe the same-sized circle of ground in each place.
