ISHS Hort Forum Episode 10: Hyperspectral Remote Sensing in Agriculture: Needed Breakthrough or Unnecessary Complexity?

Advanced technologies based on hyperspectral imagers now enable detailed estimation of crop biochemistry, fluorescence emission, plant functioning, early stress detection, and disease monitoring through physiologically-based spectral traits. This technology offers a depth of insight far beyond what traditional remote sensing systems can provide. In contrast, commercial multispectral sensors deliver only a limited set of spectral indicators relevant to agriculture, but their simplicity and the widespread availability of drone and aircraft mounted multispectral cameras make them far easier to deploy operationally. Although new machine learning and advanced AI based algorithms are rapidly reducing the computational limitations of hyperspectral data processing, promising faster, more accurate, and more automated analysis workflows, global adoption remains slow due to the persistent gap between technical capability and practical implementation. This ISHS HortForum focused on Remote Sensing Technologies will discuss about these issues in depth: complexity versus operationality, performance versus ease of use, and ultimately whether hyperspectral imaging represents a genuinely needed breakthrough for agricultural monitoring or an overstated innovation still seeking its operational role.
