## Editorial
HySIS is ISRO's Hyper Spectral Imaging Spectrometer payload, a passive optical hyperspectral imaging spectrometer for Earth-surface observation in the visible, near-infrared and shortwave-infrared regions.[^isro-hysis][^wmo-hysis-instrument] It covers 400-2500 nm across 326 detector channels: 70 VNIR channels from 400-950 nm and 256 SWIR channels from 900-2500 nm, with 10 nm spectral sampling.[^wmo-hysis-instrument] Ground sampling is 30 m over a 30 km swath.[^wmo-hysis-instrument][^eoportal-hysis] The payload is associated with vegetation and land-cover variables, and its HySIS flight has demonstrated hyperspectral classification, spectral library matching and vegetation-index mapping workflows.[^wmo-hysis-instrument] Utilization runs from 2019 to 2026 on an R&D satellite, so buyers should treat it as an operationally flown hyperspectral reference rather than a broad-revisit imaging constellation.[^wmo-hysis-instrument]
