NDVI monthly mean by Municipality

Normalized Difference Vegetation Index (NDVI) provides a quantitative measure of the amount of photosynthetically active plants on the ground at a particular place and time.

NDVI is calculated as a ratio of the difference of the Near Infrared (NIR) and the Red bands on a sensor:NDVI=(NIR-Red)/(NIR+Red)

Because vegetation has high NIR reflectance but low red reflectance, vegetated areas will have higher NDVI values compared to non-vegetated areas.

The power of the vegetation index is in comparing across time. NDVI is an excellent measure of changes in overall productivity in a region due to changes in rainfall or temperature. It is very comparable over space and time when there have not been large-scale changes in land cover.

NDVI monthly mean by Municipality

MODIS (Moderate Resolution Imaging Spectroradiometer) was launched by NASA aboard the Earth Observing System (EOS) satellite Terra on December 18, 1999. A second MODIS instrument was launched May 4, 2002 on the EOS-Aqua platform. With both instruments in operation, MODIS provides a morning and afternoon view with global, near-daily repeat coverage.
