Saint Lucia Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

The World Food Programme provides dekadal NDVI indicators for Saint Lucia aggregated from NASA MODIS collection 6.1 satellite imagery. The data tracks vegetation health across sub-national administrative units using 10-day measurements, long-term averages, and anomaly percentages. It utilizes both Aqua and Terra satellite sources to generate sub-national aggregates.

Use Cases

• Monitoring agricultural drought by analyzing the NDVI anomaly percentage (viq)
• Establishing environmental baselines for specific regions using the long-term average (vim_lta)
• Comparing current vegetation vigor (vim) across different sub-national Pcode regions

Strengths

• Uses NASA MODIS collection 6.1 as the primary sensor source
• Includes Pcode references for standardized geographic joining
• Provides n_pixels column to validate the data density of each aggregate

Limitations

• Geographic scope is restricted to Saint Lucia
• Aggregation to administrative units obscures localized spatial variance within those units
