Near-Real-Time Cheatgrass Monitoring

狠狠噜天天噜日日噜The USGS Earth Resources Observation and Science (EROS) Center produces near-real-time estimates of annual herbaceous land cover for the Great Basin, Snake River Plain, Wyoming, and contiguous areas in the United States. Estimates are based on enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) data at 250-meter resolution.
