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.

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.

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.​

This image of the Chesapeake Bay is derived from NASA Landsat 7 ETM+ and Landsat 8 OLI imagery. It represents median Normalized Difference Turbidity Index (NDTI) turbidity levels from January 2020 through June 2022. Yellow and orange areas indicate higher turbidity levels. This imagery can be used to determine areas of the bay in which turbidity poses a threat to water quality.

Median daily evapotranspiration (ET) from September 2021 to May 2022 calculated from ISS ECOSTRESS data. The image covers the agricultural fields adjacent to the Maipo River, Chile and depicts water stress. The color scale ranges from red (low ET) to blue (high ET), with higher ET observed over irrigated agricultural fields. ET is used for estimating crop irrigation requirements. This data will inform irrigation management practices and help alleviate water scarcity within the area. ​

Normalized difference vegetation index (NDVI) generated from an October 5, 2021 Landsat 8 OLI image of Yellowstone National Park. The dark green shades represent areas with healthy vegetation, yellow depicts bare ground, and intermediate shades reflect a gradient of vegetation productivity. Areas with NDVI values that vary throughout the year are indicative of deciduous vegetation and can help resource managers understand changes in aspen stand extent.​
