Using HICO data for the preparation of the future EnMAP satellite mission

Kurzfassung

This study shows first results of pre-processing products using HICO data from Venice (AAOT) in Italy in combination with data from Aqua Alta Oceanographic Towers (AERONET-OC). The primary output of this study is a first evaluation of HICO data quality in comparison to different processing algorithms, focusing primarily on atmospheric correction methods (Tafkaa 6s, ATCOR, MIP). The main objective of this study is to test and to evaluate the EnMAP (Environmental Mapping and Analysis Program) pre-processing chain using HICO hyperspectral data. A clear advantage in using HICO for testing the processing chain is the unique opportunity to have real hyperspectral satellite data with specifications comparable to the EnMAP VNIR sensor requirements. One of the foreseen standard products of the EnMAP processing chain is atmospheric correction on water and on land. Three atmospheric correction methods were employed in this investigation (Tafkaa 6s, ATCOR, MIP) and applied to two different HICO scenes for comparison on land and on water.
