Fiji Subnational NDVI: 10-Day Vegetation Indicators and Anomalies

Fiji sub-national NDVI indicators derived from NASA MODIS collection 6.1 satellite data, produced by the World Food Programme. The data provides 10-day (dekadal) vegetation health metrics aggregated by administrative units using WFP Pcode references.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against the long-term average (vim_lta)
• Identifying drought or vegetation stress using the NDVI anomaly percentage (viq)
• Validating spatial data reliability using the n_pixels column to assess observation density

Strengths

• Uses NASA MODIS collection 6.1 high-quality satellite imagery
• Includes long-term average (vim_lta) for baseline comparison
• Provides pixel counts (n_pixels) to indicate data density for each aggregate

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel-level data
• Dependent on cloud-free satellite observations which may affect pixel counts in tropical regions
