ABSTRACT

In this study, we demonstrate the implementation of an automated unmixing algorithm for the estimation of cover fractions in photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), and bare soil (BS). To develop and test the algorithm, a series of field campaigns were conducted across various locations in the United States, utilizing the Global Airborne Observatory (GAO) equipped with visible-to-shortwave infrared (VSWIR) spectrometer technology. This imaging capability facilitates the quantification of diverse land and ocean ecosystem properties. Here, the Automated Monte-Carlo Unmixing (AutoMCU) algorithm was applied to an example dataset collected from a research farm in Iowa, US, yielding consistent results across different spatial scales, atmospheric corrections, and iterations.
