Earth Observing-1 (EO-1) Hyperion Hyperspectral

Earth Observing-1 (EO-1) Hyperion hyperspectral signatures of some of the vegetation in the African rainforest.

Detailed Description

Figure 8: Hyperspectral Hyperion data acquired over African rainforest ar used to study spectral characteristics of the rainforest vegetation as illustrated. For example, the highest spectral reflectivity in the near infrared (NIR) bands is for the bamboo forests whereas the same vegetation has greatest absorption in the visible. In contrast the slash-and-burn agricultural fields have high reflectivity in the visible red bands, low reflectivity in the NIR, and high reflectivity in the 2000 to 2400 nm range. All these subtle and not-so-subtle differences are characterized through qualitative and quantitative approaches. Given the rich spectral data in 100s or 1000s of hyperspectral narrowbands (HNBs) and the ability to establish unique hyperspectral vegetation indices (HVIs) using hyperspectral data such as from EO-1 Hyperion, there are many advances that can be made in the study of agricultural-crops and other vegetation.
