Earth vegetation globes. Artwork of Earth globes with vegetation cover pictured as a scale, or index of greenness. Greenness is based on several factors: the number and type of plants, how leafy they are, and how healthy they are. In places where foliage is dense and plants are growing quickly, the index is high, represented in dark green. Regions where few plants grow have a low vegetation index, shown in tan. The index is based on measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA'Âs Terra satellite (operating in Earth orbit since 2000). Areas where the satellite did not collect data are grey.
