Meta 1 m canopy height against dated imagery, Uganda

Uganda. Meta's heights at their native 1.19 m grid inside 72 windows around the 183 drawn coffee polygons and the 34 icipe sites (1,543 km²), a 19 m layer everywhere else, and Esri Wayback imagery by date. Lab index.

Same tiles as the public coffee map, read directly from it; pixels below the "show from" probability are hidden, and the layer is drawn under the canopy layers. Below zoom 14 the tiles hold averaged probabilities, which rarely reach 0.80: lower the slider to see where coffee concentrates, or zoom in for the real 10 m values.

Meta image dates

Acquisition footprints, coloured by year

From Meta's own metadata: the date of the Maxar image behind each footprint. Pick the imagery release nearest that date to see what the model saw.
