Angola Subnational NDVI: 10-Day Vegetation Indices and Anomalies

A source of dekadal (10-day) NDVI vegetation indicators for Angola, aggregated at sub-national administrative levels by the World Food Programme. It utilizes NASA MODIS collection 6.1 satellite data from both Aqua and Terra platforms to track vegetation health through current values, long-term averages, and percentage anomalies. The data is mapped to specific administrative units using standardized WFP Pcodes.

Use Cases

• Monitoring agricultural drought conditions by comparing current vim against the vim_lta baseline
• Identifying regional vegetation stress using the viq anomaly percentage
• Correlating vegetation health with food security outcomes using WFP Pcode join keys

Strengths

• Uses NASA MODIS collection 6.1 high-quality satellite data
• Includes n_pixels column to provide transparency on the data density of each aggregate
• Utilizes standardized WFP Pcodes for interoperability with other humanitarian datasets

Limitations

• Aggregated format obscures local-level vegetation variations smaller than the administrative unit
• NDVI values can be affected by persistent cloud cover in tropical regions
