Evaluating scale dependence of ecosystem service valuation: a comparison of NOAA-AVHRR and Landsat TM datasets

摘要

The purpose of this study is to determine how the spatial scale of measurement influences ecosystem service valuation. Two land cover datasets were compared: one classified from 1-km imagery and one classified from 30-m imagery. The coarse resolution biome dataset used in this study(called the International Geosphere Biosphere Programme(IGBP)Dataset) was classified from 1-km NOAA_AVHRR imagery and includes 17 biome types. The Finer resolution National Land Cover Dataset (NLCD) used in this study was classified from 30-m Landsat Thematic Mapper imagery and has 21 land-cover classes.
