Comparison of different approaches of selecting endmembers to classify agricultural land by means of hyperspectral data (DAIS7915)


Kneubühler, Mathias; Schaepman, Michael E; Kellenberger, Tobias W (1998). Comparison of different approaches of selecting endmembers to classify agricultural land by means of hyperspectral data (DAIS7915). In: IGARSS 1998, Seattle, USA, 6 July 1998 - 10 July 1998, 888-890.

Abstract

A major problem in classification of hyperspectral datasets is the reliable selection of reference spectra to classify heterogeneous vegetated areas. In this work, different approaches of end-member collection for spectral unmixing of hyperspectral data are presented, evaluated and compared to each other. The selected methods include high resolution ground spectroradiometric measurements, a scene based approach and modelling of the end-member spectra using a SVAT (soil-vegetation-atmosphere-transfer) approach. The presented methods are discussed and verified with an extensive ground truth collected in the observed area.
