Method and limits
- Sentinel-2 true colour at 10 m per pixel, so single houses are not visible.
- One clear dry-season acquisition per year; seasons and sun angle still differ slightly between years.
- Green cover is an RGB approximation of green-dominant pixels, not NDVI.
- Clouds, haze and shadows can remain in a scene even after selection.
Contains modified Copernicus Sentinel data, processed by MapScale.
