Extended Data Fig. 1: Planet NDVI time series for 308 trees contrasted with the background NDVI from the same area.
From: Sub-continental-scale carbon stocks of individual trees in African drylands
a, Note the separation between the tree NDVI values and the background NDVI for the dry-season months of November to March. b, False-colour tree crown NDVI image from WorldView-3 at 30-cm spatial resolution showing green leaf vegetation in red colours. Individual trees are evident, with green leaf tree crowns with associated shadows. Our mapping of trees with machine learning is based on trees defined as having a tree crown of at least 3.0 m2 with an associated shadow. Areas of low vegetation do not cast shadows sufficiently to be classified as trees. The areas in a and b are close to 13° 31′ N × 2° 40′ E.
