The key metric is the Normalized Difference Vegetation Index (NDVI), derived from near-infrared and red bands, ranging from -1.0 to 1.0, with a pixel size of 30 meters. Composites include all images within each 32-day period, with the most recent pixel value used, with some imagery exculded based on date and orbit. The data is in the public domain, and users should credit the USGS.\n"],null,[]]
