Haiti Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

Dekadal NDVI indicators for Haiti aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. The World Food Programme (WFP) produced this dataset to track vegetation health through current values, long-term averages, and anomalies. The data was last updated in March 2026.

Use Cases

• Assessing agricultural drought severity by comparing `vim` to `vim_lta`
• Mapping regional vegetation stress using `viq` anomaly percentages
• Integrating environmental data into food security models via Pcode join keys

Strengths

• Uses NASA MODIS collection 6.1 satellite data
• Includes Pcode references for administrative units
• Provides `n_pixels` for aggregate reliability assessment

Limitations

• Aggregated format obscures local-level vegetation variations within administrative units
• NDVI values can be affected by persistent cloud cover in tropical regions
