The level 4 FINCH-Science-MissionSuccessLevels for FINCH requires our ability to successfully estimate the amount of crop residue (AKA non-photosynthetic vegetation or NPV) contained within agricultural areas before and after tillage events. Using hyperspectral data, the process of crop residue estimation falls under the umbrella term of Spectral Mixture Analysis (SMA) (See https://drive.google.com/file/d/1Z17w0xR-NNGIogGzgIy-R_kDDA1L2T_W/view). There are dozens of approaches to crop residue estimation using SMA. A long term analysis of different methods and databases will determine the ideal methods and scenarios for NPV unmixing using the FINCH satellite. An overview of our architecture can be found here Abundance Estimation Pipeline Architecture. Our spectral library for analysis can be located here Build Preliminary Spectral Library.
