The DESIS and PRISMA Derived Spectral Library of Agricultural Crops in California was developed using 2020 DESIS and PRISMA data for almonds, corn, cotton, grapes, pistachios, rice, and tomatoes. For more details, see “New Generation Hyperspectral Sensors DESIS and PRISMA Provide Improved Agricultural Crop Classifications” (DOI: 10.14358/PERS.22-00039R2)

When soil behaves like a liquid it can lose its ability to support structures. The soil can even flow down very gentle slopes, and erupt to the ground surface to form sand boils (“sand volcanoes”).

We are developing multi-scale methods to capture the phenology of cheatgrass with harmonized Landsat and Sentinel satellite imagery, high resolution Planet imagery, and experimenting with centimeter-scale uncrewed areal systems (UAS) multispectral imagery.

Exotic annual grasses such as cheatgrass (Bromus tectorum) have heavily invaded portions of the western United States, rapidly degrading habitats and increasing wildfire risk.
