Gambia Subnational NDVI: 10-Day Vegetation Indices and Anomalies

Delivering dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for Gambia, aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme (WFP), the data tracks vegetation health through current readings, historical averages, and percentage anomalies. The records are updated through March 2026 and include statistical metadata for each administrative unit.

Use Cases

• Monitoring agricultural productivity by comparing vim against vim_lta
• Detecting drought or environmental stress using the viq anomaly percentage
• Mapping regional vegetation trends using Pcode administrative references

Strengths

• Derived from NASA MODIS collection 6.1 Aqua and Terra satellite sensors
• Includes vim_lta for direct comparison against historical baselines
• Provides n_pixels count to indicate the data density of each aggregated unit

Limitations

• Geographic scope is restricted to Gambia
• Aggregated format obscures pixel-level spatial variations within administrative units
