Abstract:

This study was conducted to develop detect methods of the citrus greening disease (HLB) from citrus groves using ground-based, airborne and satellite imaging. Airborne multispectral and hyperspectral images were acquired multiple times over a five-year period (2007-2012) in Florida. Worldview-2 multispectral satellite images were also acquired and used to detect HLB infected citrus canopies. Various classification and detection methods were developed and varying degrees of detection accuracies were obtained depending on the accuracies of ground-truthing data and the quality of spectral libraries. Ground-based HLB detection systems were developed and tested in citrus groves, which yielded promising results.
