![NDVI over Mato Grosso, Brazil processed from March 2021 Landsat-8 OLI data. Calculated NDVI values correspond with colors shown to indicate plant health. High NDVI values (green to blue) indicate dense vegetation found in tropical and temperate forests or crops at their peak growth. Low values (yellow to red) depict barren land, water, and moisture-stressed vegetation. These data can support timely and efficient agricultural responses to ensure productive yields and food security.](/sites/default/files/styles/lis/public/2022-12/2022Sum_NC_MatoGrosso_WebsiteImage_FD.png.webp?itok=JJA3kKJi)

![NDWI-processed composite image from Landsat 8 OLI data of the Lower Illinois River Valley and surrounding landscapes from summer 2021. Shades of pale yellow indicate dry vegetation and dark teal represents open water, while brighter turquois values depict wet vegetation. Areas of high NDWI values are demonstrative of high presence of wet vegetation and are of interest to the Great Rivers Land Trust in identifying areas of interest for wetland conservation.](/sites/default/files/styles/lis/public/2022-12/2022Sum_JPL_LowerIllinoisEco_WebsiteImage.png.webp?itok=eCvz2h8C)
