We compared hyperspectral data from EO-1 Hyperion and spectrometric data from the spectrometer ASD FieldSpec 3F to evaluate the Red Edge Position of reflectance spectra for different land cover types within the test area of the Mariinskyi park in Kyiv. The satellite EO-1 Hyperion image made on 14 September 2002 and ground-based ASD FieldSpec 3F measurements performed on 15 April 2009 and 16 September 2009 were used. A relationship between the REP value and calculation method and image processing level is deduced. The four-point linear interpolation method for REP calculation from the atmospheric-corrected satellite data gives the results which are closest to the data calculated with the use of ground-based measurements of grass canopy.
