Description
Supplying dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for Chile, aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme (WFP), the records include current NDVI values, long-term averages, and percentage anomalies.
Use Cases
Analyzing agricultural trends by comparing vim against vim_lta
Detecting drought or vegetation stress using the viq anomaly percentage
Assessing data reliability per region using the n_pixels count
Strengths
Derived from NASA MODIS collection 6.1 satellite data
Includes vim_lta for historical baseline comparison
Uses standardized WFP Pcode references for administrative units
Limitations
Spatial resolution is limited to sub-national administrative aggregates rather than raw pixels
Data accuracy is subject to cloud cover interference inherent in MODIS optical sensors
