Uganda Subnational NDVI: 10-Day Vegetation Anomalies by WFP Admin Units

Dekadal (10-day) NDVI vegetation indicators for Uganda's sub-national administrative units, derived from NASA MODIS collection 6.1 satellite imagery. Produced by the World Food Programme (WFP), the data aggregates spectral observations into administrative boundaries to monitor agricultural health and drought conditions.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against long-term averages (vim_lta)
• Identifying drought or flood impacts using the NDVI anomaly percentage (viq)
• Analyzing vegetation trends across specific WFP administrative Pcodes for food security planning

Strengths

• Uses NASA MODIS collection 6.1 high-quality satellite data
• Includes long-term averages (vim_lta) for historical baseline comparison
• Provides pixel counts (n_pixels) to indicate the statistical reliability of each aggregate

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel-level data
• NDVI values can be affected by cloud cover interference in the underlying MODIS imagery
