## Editorial
Zhuhai-1 OHS hyperspectral imager is the passive optical hyperspectral payload used by the Zhuhai-1 OHS satellites.[^obt-zhuhai1][^mdpi-urban-tree-zhuhai1] The sensor images at 10 m spatial resolution with a 150 km footprint width.[^obt-zhuhai1] The imagery is commonly handled as 32 spectral bands in the 400-1000 nm VNIR range.[^mdpi-urban-tree-zhuhai1][^nature-ohid1] Zhuhai-1 OHS data has demonstrated use for hyperspectral classification, including land-cover and urban tree-species work.[^mdpi-urban-tree-zhuhai1][^nature-ohid1]
