Are urban material gradients transferable between areas?

Chaonan Ji, Uta Heiden, Tobia Lakes, Hannes Feilhauer

Abstract: Highlights•Urban material gradients can map cities with spaceborne hyperspectral images.•The gradient mapping does not require prior determination of pure pixels.•This study evaluated the transferability of urban material gradients to a new area.•The results show the transferability potential of these gradients.
