  • A survival guide to Landsat preprocessing 

    Young, Nicholas E.; Anderson, Ryan S.; Chignell, Stephen M.; Vorster, Anthony G.; Lawrence, Rick L.; Evangelista, Paul H. (2017-04)
    Landsat data are increasingly used for ecological monitoring and research. These data often require preprocessing prior to analysis to account for sensor, solar, atmospheric, and topographic effects. However, ecologists ...

    Holbrook, Joseph D.; Squires, John R.; Olson, Lucretia E.; Lawrence, Rick L.; Savage, Shannon L. (2017-01)
    Snowshoe hares (Lepus americanus) are an ecologically important herbivore because they modify vegetation through browsing and serve as a prey resource for multiple predators. We implemented a multiscale approach to ...
