Colombia Subnational NDVI: Dekadal Vegetation Indices and Anomalies

World Food Programme (WFP) provides dekadal NDVI indicators for Colombia aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. The records include 10-day vegetation indices, long-term averages, and percentage anomalies for environmental monitoring.

Use Cases

• Monitoring drought conditions by analyzing the `viq` (NDVI anomaly) column across dekads
• Evaluating seasonal vegetation growth patterns using the `vim` 10-day indicator
• Integrating environmental data with humanitarian surveys using the provided Pcode administrative references

Strengths

• Derived from NASA MODIS collection 6.1 Aqua and Terra satellite data
• Includes `vim_lta` (long-term average) for 10-day historical baseline comparisons
• Contains `n_pixels` counts to validate the statistical significance of each administrative aggregate

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel-level data
• Subject to satellite sensor limitations and cloud cover interference in the original MODIS feed
