Monitoring Post-Fire Vegetation Regeneration of the 2003 Burned Areas in Portugal using a Time-Series of MODIS Enhanced Vegetation Index
Our objective is to monitor vegetation recovery after the large
fires of 2003 in Portugal. We use a time-series of MODIS Terra Enhanced
Vegetation Index (EVI) data, at 250 m spatial resolution and with 16-day
image composites (MOD13A1 product). These data were screened with the
Time Series Generator (TiSeG) software, to detect and replace bad or missing
data. The analysis begins in early 2000, to characterize pre-fire vegetation
dynamics, extends until late 2008, and relies on fire perimeters
mapped from Landsat imagery at 30m spatial resolution to locate the 2003
fires. Three sample fires were selected for preliminary visual analysis of EVI
time series within and outside the fire perimeters, and observed differences
are discussed as a function of pre-fire land cover.
