**3.9. Vegetation indices from satellite images: MTCI index**

USGS EO-1 Hyperion image was that acquired on 15 February 2005. Hyperion data have a spatial resolution of 30 m2 with each pixel covering the spectral range, 400–2500 nm. A single image is 7.65 km wide (cross-track) by 185 km long (along-track) covering the study sites 1 and 2 (secondary disturbed sites). After atmospheric and radiometric corrections, see more details in [62], MTCI index was derived to assess from space the main impacts of land use changes on chlorophyll content in the tropical forest.
