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. Salvaleón de Higüey leads here at 37.3%.
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: Salvaleón de Higüey reads 33 (good) and San Pedro de Macorís reads 38 (good) right now.
Frequently asked
Salvaleón de Higüey and San Pedro de Macorís, answered
Which has more trees, Salvaleón de Higüey or San Pedro de Macorís?
Salvaleón de Higüey, with roughly 117,181 trees inside its 2 km radius against 59,282. Tree cover tells a slightly different story from raw count: Salvaleón de Higüey has the denser canopy at 37.3%.
Which has better air quality, Salvaleón de Higüey or San Pedro de Macorís?
Salvaleón de Higüey right now, at AQI 33 against 38 — a gap of 5 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?
Salvaleón de Higüey needs about 0 more to reach its canopy target, and San Pedro de Macorís about 20,829. 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.
