ACOLITE and NDVI processed imagery from Landsat 9 OLI-2 data. This composite image of the Coos Estuary and surrounding area was taken in September of 2022 after a period of increased precipitation. Shades of blue indicate vegetated land surface. The darker purple indicates higher turbidity while the lighter orange indicates lower turbidity.

Tasseled Cap Wetness calculated from Landsat 9 OLI-2 imagery from October 25, 2022. The Paria River, shown in dark blue, passes through the landscape. Shades of lighter blue indicate higher values of Tasseled Cap Wetness, with the gradient going towards dark purple and then bright pink for the lowest values of Tasseled Cap. Areas with higher Tasseled Cap Wetness values indicate moister environments, which can enable invasive species proliferation in riparian ecosystems.

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.

A 3D rendering of Landsat 8 OLI data processed using a Normalized Difference Moisture Index (NDMI). This image of the southeast region of Bandelier National Monument was taken on September 10, 2022. The Rio Grande is shown on the right side in dark purple, with upland areas shown in light green. NDMI highlights the areas of high moisture content, around which vegetation is more prevalent, as seen in indigo.

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.
