Assessing vegetation coverage at the Sao Paulo state scale: a tool for aiding the decision making process.

This methodology needs to be validated with in-situ data. The thresholds of the NDVI values used to calculate the vegetation cover (NDVIS and NDVIV) may be changed depending on the length of the time series available and also on the area of interest.

In this case, other geographical limits of analysis need to be adopted, like the extents of a certain land use regions, the boundaries of watersheds or of parks and protected areas
