![Impervious surface imagery derived from Landsat 9 OLI-2 data. This composite was captured over the Finger Lakes region between April and October of 2022. Blue hues indicate dense vegetation while yellow hues indicate impervious areas. Areas in green indicate agricultural fields of interest to NGOs in the region that aim to prevent the conversion of agricultural lands to urban development.](/sites/default/files/styles/lis/public/2024-01/2023Sum_PUP_NewYorkEco_WebsiteImage.jpg.webp?itok=gjo4ogVR)

![Landsat 8 OLI derived MNDWI imagery mosaicked from October 17, 2020, to December 2, 2020. Located near the Río Patuca (Patuca River) in Ahuas, Honduras, permanent water and flood is represented as bright red and orange while blue depicts other land cover types and clouds. Examining floods from disasters like Hurricanes Eta and Iota helps decision makers improve mitigation and response efforts.](/sites/default/files/styles/lis/public/2022-03/2021Fall_MSFC_CentralAmericaDisasters_WebsiteImage.png.webp?itok=pweSILBO)

![Magnitude of largest model break in Continuous Change Detection Algorithm harmonic regression model, indicative of clearcut logging in the Oregon coast range forests. Imagery from Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI from across the study period 2000-2021 over standard hill shade. Patches of blue show clear cut areas with lavender then yellow indicating higher magnitude. Green areas represent forests untouched during the study period.](/sites/default/files/styles/lis/public/2024-01/2023Sum_MA_OregonCoastRangeEco_websiteImage.jpg.webp?itok=sGJs5DSB)

![Predicted cheatgrass green-up imagery from Landsat 8 OLI data. This composite image of the western portion of the Mullen Fire Study Area is from June 2022. Shades of green and yellow indicate an earlier green-up time, while orange, brown, and white areas show later predicted green-up times. This data was used to create NDVI difference maps which will help managers predict when and where to apply treatments to limit the spread of cheatgrass.](/sites/default/files/styles/lis/public/2023-10/2023Sum_CO_SouthernWyomingEcoII_WebsiteImage.jpg.webp?itok=Ht2hUpEj)

![Annual max biomass calculated from 2021 daily Harmonized LandSat Sentinel-2 (HLS) dataset. Dark purple colors show low biomass while the bright orange show high biomass. Regions with high vegetation and tree canopy cover are shown in orange on the left of the image. High biomass values are of an interest to rangeland managers to help inform their grazing decisions based on which areas of the ranch produce the most biomass/vegetation.](/sites/default/files/styles/lis/public/2023-02/2022Fall_CO_EasternPlainsAgr_WebsiteImage.jpg.webp?itok=StO3rYYa)

![Forest cover and land surface temperature (LST) around Maine's Penobscot River during Summer 2021. The shades of green distinguish between evergreen (dark) and deciduous (light) forest which were classified using Landsat 8 OLI imagery. The purple gradient corresponds to LST derived from Terra MODIS where the warmest areas, including Bangor, are white. Changing land use and warming temperatures along Maine’s rivers are associated with reducing juvenile Atlantic salmon (Salmo salar) survivorship.](/sites/default/files/styles/lis/public/2022-11/2022Sum_GSFC_MaineEcoIII_WebsiteImage.jpg.webp?itok=EiYDdUqO)
