Panel A shows the maps in the context of the African continent while Panel B gives larger views of the maps (countries not to scale). Blue and red indicate regions of high or unanimous agreement between maps for the crop and non-crop classes, respectively. Yellow indicates regions of high disagreement between maps. charts - Time series of 16-day MODIS MOD13A1.061 Terra Vegetation Indices averaged within (A) each country and (B) an administrative level 1 region, masked using each crop mask assessed in this study. photo - farmer, Atsbi, Tigray, Ethiopia
