MapSPAM 2010 coffee, 9 km cells

Opacity0.65
0 ha
Modelled statistics (IFPRI SPAM), not field truth: census totals spread over 5 arc-minute cells, about 8,600 ha each. Click a cell for arabica, robusta, banana and tea.

Extracted points, Google coffee probability

Min probability0.00
00.51
Probability from Google's Forest Data Partnership coffee model (2026a release, 2024 layer), sampled at the points when they were extracted. Grey points were never sampled from that layer: drawn polygons, NAEB tea plantations, CIAT annual crops. Click a point for its class and source.
