Long-Wave Infrared

Long Wave Infrared (LWIR) refers to multi- and hyperspectral data collected in the 8 to 15 µm wavelength range. LWIR surveys are sometimes referred to as "thermal imaging" and can be used to identify relatively warm features such as hot springs, fumaroles, and snow melt. LWIR can also be used to map the distribution of certain minerals related to hydrothermal alterations.[2]
