N2 - In this study, spatio-temporal patterns of continuous forest cover in Kalimantan from 1982-2009 were examined using the patterns observed in metrics calculated with AVHRR, VEGETATION and MODIS measurements. Four analytical approached were used; calculation of temporal mean, maximum and minimum layers for selected metrics showing significant spatial variability of channel 1, 2, NDVI and EVI; linear discriminant for input into the un-mixing analysis was derived from the same multi-temporal metrics used for the classification product using Landsat MSS/TM/ETM and ALOS PALSAR and AVNIR2; the continuous percentage of forest cover was generated based on un-mixing technique with the training data. The derived metrics were not sensitive to the time of year or the seasonal cycle and can limit the inclusion of atmospheric contamination. The comparison of MODIS 250m forest cover product with the past efforts on AVHRR, VEGETATION and MODIS sensors showed that the finer resolution and its un-mixing played a crucial role in depicting the forest cover.
