Abstract

We investigated the use of the MODIS vegetation indices and the effect of distinct change thresholds for monitoring land cover change in the Cerrado biome, the largest region of neotropical savanna vegetation in the world and the most threatened biome in Brazil. On a preliminary basis, our results suggest the use of change thresholds between 35 and 42% and the us pe of the enhanced vegetation index (EVI), which, in comparison to the normalized difference vegetation index (NDVI), showed a more stable and predictable behaviour.
