Vegetation productivity decline calculated from the yearly maximum NDVI for 1986–2021, derived from Landsat 5/7/8 data, and overlaid on a 2021 Landcover Change Monitoring System composite, constructed from Landsat 8 OLI. Blue, purple, and pink represent grasses & forbs, shrubs, and trees respectively. Red over pink likely indicates beetle and drought disturbance. Data can be used to inform management and prepare public land for ecological change in the Grand Valley region of Colorado.

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.

Median June composite of daily evapotranspiration from ECOSTRESS before the start of the Bootleg Fire on July 6th, 2021. Evapotranspiration is shown in millimeters per day across Klamath and Lake counties in Oregon, with dark blue indicating areas with higher evapotranspiration and light tan indicating lower evapotranspiration. Evapotranspiration is an indicator of vegetation moisture and can aid wildfire modeling by locating areas undergoing water-stress and susceptible to fire.

NDMI over a wildland urban interface in central Chile generated from Landsat 8 OLI median-reduced data from March 1, 2018 through February 28, 2022. Orange areas represent vegetated shrublands and forests with low moisture content and green areas representing vegetated agricultural areas with high moisture content. The NDMI was used as a proxy for wildfire fuel moisture in a wildfire risk assessment.

The image displays NDVI calculated over the Guadalupe Mountain Range in Western Texas captured May 2020 by Landsat 8 OLI. Areas shaded green indicate tree canopy while yellow and red areas indicate arid landscapes. NDVI was used to visualize vegetation health and inform the National Park Service’s future management initiatives.

Enhanced Wetland Classification of the Slave River Delta, NWT, Canada using Landsat 8 OLI imagery from June through August 2021.  Most of the colors represent different categories of wetland.  Many of the darker green areas represent areas where wetlands have transitioned to dryer forests or shrubs in recent decades.

Top layer: NDTI processed imagery of Lake Champlain derived from Landsat 8 TOA data (5/1/21 - 9/30/21). Bright orange and red represent areas of greater turbidity, which often corresponds to algal presence, whilst dark areas indicate low turbidity. Bottom layer: Slope imagery from SRTM (last updated 11/2018) of the Lake Champlain Watershed. Yellow shows areas with higher slopes, which have a greater risk of phosphorus runoff, while blue shows areas with a lesser slope.

False-color imagery from Landsat 8 surface reflectance. The 2021 median composite image depicts the landscape and vegetation sites in the regions of western Bhutan, specifically the districts of Punakha, Wangdue Phodrang, Thimphu, and Paro. The band combination highlights fallow agriculture fields in light brown, dense urban areas in purple, forest cover in green, snow in light blue, and rocky areas in darker brown.
