Abstract :
Data from the Moderate Resolution Imaging Spectroradiometer (MODIS) represent a marked advance in global land cover mapping. The 500 m time series data have an improved spectral/spatial response when compared to heritage instruments. This study presents the first results from the Vegetation Continuous Fields algorithm of the MODIS land cover product suite. A regression tree is run using multitemporal metrics derived from a single year of MODIS data. Initial products include percent tree cover, percent short vegetation cover and percent bare ground. The results reveal the improved spatial/spectral characteristics of the MODIS data compared to the AVHRR (Advanced Very High Resolution Radiometer).
