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.

Runoff retention values in Richmond, VA estimated by the InVEST Urban Flood Risk Mitigation Model for a June 2, 2018, extreme rainfall event measured by GPM IMERG. Dark blue areas have high runoff retention capacity and absorbed more of the rainfall during the storm; light green areas absorbed less rainfall during the storm, increasing the likelihood of pluvial flooding. Pluvial flood risk maps help inform community planners’ efforts to protect vulnerable populations.

Albedo derived from Landsat 8 & 9 OLI data throughout summer 2019 to 2023. White beige pixels signify effective solar radiation reflection (higher albedo), followed by peach, violet, and dark purple. This data is input for the InVEST Urban Cooling model, which calculates heat dissipation efficiency. Light-colored roofs and dense vegetation can increase albedo. Urban areas with lots of purple patches may be more vulnerable to heat, making them a priority for heat mitigation efforts.

NDVI map calculated from an April 2023, Landsat-8 OLI image of Coronado National Memorial and the surrounding area. The shades of green represent current vegetation, while areas in bright yellow and dark orange represent areas with little to no vegetation. By selecting an image during the dry season, the map highlights the unique ecosystem of sky islands which is characterized by changing vegetation at different elevations.
