The Coleambally agricultural component of hyperion instrument validation

Abstract

The Coleambally Irrigation Area (CIA) in southern New South Wales, Australia, is an agricultural site used in support of validation of the hyperion imaging spectrometer onboard the earth observing-1 (EO-1) satellite. A time series of hyperion imagery has been acquired over the CIA during the 2000/2001 southern hemisphere summer growing season. Within the CIA, there are five different varieties of rice and several row crops grown, specifically corn, soy beans, and sorghum. Imagery has been acquired prior to rice canopy closure, pre panicle initiation, at panicle initiation, during grain filling and after senescence. Extensive in situ ground sampling was also performed several times during the growing season to validate the spectral signatures received from hyperion. In this paper, we describe the databases developed that will be used in future instrument validation efforts. This project also demonstrates successful integration of a time series of hyperspectral imagery to relevant land use and other spatial data.
