Data in GLAM

Imagery Products There are different imagery products available on the GLAM platform. Vegetation Indices MODIS/Terra NDVI 8-Day MODIS/Terra NDVI 16 Day MODIS/Terra Near Real Time (NRT) NDVI MODIS/Aqua NDVI 8 Day MODIS/Aqua NDVI 16 Day VIIRS NDVI 8 Day MODIS/Terra NDWI 8 Day Other Products CHIRPS Precipitation Copernicus Soil Water Index MERRA-2 Mean Temperature More information about temporal and spatial resolutions and other characteristics of the data can be founds in the GLAM web application. Crop Masks The primary crop mask data used by the GLAM system is from the GEOGLAM Global Best Available Crop Specific Masks (GEOGLAM-BACS). The GEOGLAM Best Available Crop Specific masks (BACS) cover the major production and export countries for wheat, maize, rice, and soybeans, in the context of the G20 Global Agriculture Monitoring Program, GEOGLAM. Boundary Layers Administrative boundaries used in the GLAM system are courtesy of geoBoundaries. The geoBoundaries is world's largest open database of administrative boundaries at different levels. More information about these layers can be found at geoBoundaries.
