Deforestation · 2001–2025
Which has lost more forest, Hat Yai or Latkrabang?
Hat Yai has lost more: about 4,770 ha of forest within 10 km of its center from 2001 to 2025, against 19 ha around Latkrabang. 4,760 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2017, with 409 ha lost.
Worst year: 2001, with 5 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.

Are Hat Yai and Latkrabang measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Latkrabang is read from a nearby ground station and Hat Yai is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Hat Yai vs Latkrabang comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Aug 3, 2026 and Aug 3, 2026), and the forest figures are published yearly.
