Mapping pastures in Eastern Australia with NOAA-AVHRR NDVI and Landsat TM data

摘要

Monthly NOAA-AVHRR NDVI data, and single date Landsat TM data at 10 sites within the AVHRR area, were used to classify pastoral land cover for the high rainfall zone of SE Australia for 1993. NDVI profiles and Landsat TM pixel compositions for typical pasture types are presented for a summer rainfall area in northern NSW and a seasonal Mediterranean climate in Western Victoria. Agreement between the classification and results of a survey of pasture types by professional agriculturalists is examined.
