N<strong>or</strong>malized Difference Vegetation Index<br />

The N<strong>or</strong>malized Difference Vegetation Index (NDVI) is derived from environmental<br />

data collected by the Advanced Very High Resolution Radiometer (AVHRR) sens<strong>or</strong> on board<br />

the National Oceanic and Atmospheric Administration (NOAA) polar-<strong>or</strong>biting<br />

mete<strong>or</strong>ological satellite. The AVHRR rec<strong>or</strong>ds 5 bands <strong>of</strong> spectral data f<strong>or</strong> the entire Earth<br />

daily. Data rec<strong>or</strong>ded from these spectral bands are available at a resolution <strong>of</strong> 8km x 8km as<br />

daily and composite products from 1981 to the present (Estrada-Pena 1998, NASA EO<br />

2008). The 8 km AVHRR NDVI product was selected because 8 km resolution data can blur<br />

some landscape heterogeneity present in urban regions <strong>of</strong> the study area.<br />
