Preprocessing EO-1 Hyperion hyperspectral data to support the application of agricultural indexes

TL;DR: Preprocessing, which includes fixing bad and outlier pixels, local destriping, atmospheric correction, and minimum noise fraction smoothing, provides improved results and it is feasible to develop a consistent and standardized time series of data that is compatible with field-scale and airborne measured indexes.
Journal ArticleDOI

On the relationship between training sample size and data dimensionality: Monte Carlo analysis of broadband multi-temporal classification

TL;DR: In this paper, a Monte Carlo procedure was used to randomly stack various numbers of bands into thousands of separate image combinations that were then classified using an ML algorithm, and 95% of the accuracy attained using n = 30p samples could be achieved by using approximately 2p to 4p samples, or ≤ 1/7th the currently recommended value of n.
Proceedings ArticleDOI

Improving the analysis of Hyperion red-edge index from an agricultural area

TL;DR: In this article, the benefits of EO-1 data, and especially Hyperion hyperspectral data, are studied at sites in the Coleambally Irrigation Area of Australia where a seasonal time series has been developed.
Proceedings ArticleDOI

Time series analysis of EO-1 Hyperion data for yield estimation at an agricultural site

TL;DR: Results show that new hyperspectral indices such as the first derivative value and wavelength position of the red edge inflection point are more sensitive to within-paddock variations in yield than commonly used indicessuch as NDVI.
Proceedings ArticleDOI

Assessing the value of a time series of EO-1 data for Coleambally Irrigation Area

TL;DR: The basic processing steps that have been applied to geometrically and atmospherically correct the data and reduce the effects of noise prior to investigating the time series of specific measures of crop productivity through its biochemistry are described.
