![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)

![The image was collected by Landsat 9 on January 26 of 2023 showing Skidaway Island and waterways on the Georgia coast. The data shows areas of healthy vegetation and urban areas using a Normalized Difference Vegetation Index (NDVI). The darker orange represents grass and urban areas. Yellow and purple represents forested and densely vegetated areas. The black represents open water.](/sites/default/files/styles/lis/public/2023-05/2023Spring_GA_GeorgiaDisastersII_WebsiteImage.jpg.webp?itok=zhMhpiSz)

![Normalized Difference Water Index (NDWI) to visualize drainage networks around the Unalakleet River in Alaska, calculated from an August 2021 Landsat 8 OLI image. Yellow represents standing or flowing water and potential flood zones, while the dark blue represents drier, upland regions. Unalakleet's climate resilience planning prioritizes relocation to upland regions while avoiding areas that have experienced significant permafrost degradation.](/sites/default/files/styles/lis/public/2023-10/2023Sum_GA_UnalakleetClimate_WebsiteImage.jpg.webp?itok=9m9RUwoB)
