Crop Residue StudyPurpose: We will collect traditional crop residue cover percentage measurements using line transect methods and also collect ultra-fine spatial resolution UAS data over the same field. The UAS data will provide means to generate wall-to-wall estimates of crop residue cover percentage of each field, which then can be used to scale the crop residue cover percentage estimation using spaceborne remote sensing technology.
