Iran Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

Dekadal Normalized Difference Vegetation Index (NDVI) indicators for Iran are provided here at sub-national administrative levels by the World Food Programme. The data utilizes NASA MODIS Collection 6.1 imagery from Aqua and Terra satellites to monitor vegetation health and anomalies over 10-day intervals.

Use Cases

• Monitoring crop health by comparing `vim` against `vim_lta` across sub-national regions
• Identifying drought-affected areas using the `viq` anomaly percentage
• Spatial analysis of vegetation trends using WFP Pcode references for mapping

Strengths

• Derived from NASA MODIS Collection 6.1 satellite data
• Includes historical baselines via the `vim_lta` column
• Uses standardized WFP Pcode references for administrative units

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixels
• Data quality in specific units may vary based on the `n_pixels` count
