Georgia Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Dekadal NDVI indicators for Georgia's sub-national administrative units are derived from NASA's MODIS collection 6.1 satellite imagery. Produced by the World Food Programme (WFP), the records include 10-day vegetation indices, long-term averages, and percentage anomalies. The data is aggregated using WFP administrative boundaries and includes pixel counts for each unit.

Use Cases

• Assessing crop health by comparing current 10-day NDVI (vim) against the long-term average (vim_lta)
• Detecting regional drought stress using the NDVI anomaly percentage (viq)
• Evaluating the statistical reliability of administrative aggregates using the pixel count (n_pixels)

Strengths

• Derived from NASA MODIS collection 6.1 satellite data
• Includes Pcode references for standardized joining with WFP geographic datasets
• Provides historical context through the long-term average (vim_lta) field

Limitations

• Spatial resolution is limited to sub-national administrative aggregates rather than raw pixel values
• Temporal resolution is restricted to 10-day (dekadal) intervals
