Viet Nam: Subnational NDVI and Vegetation Anomalies by Dekad

A source of dekadal NDVI indicators for Vietnam aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme, it tracks vegetation health through 10-day intervals, long-term averages, and percentage anomalies.

Use Cases

• Monitoring seasonal crop health trends using the vim vegetation index
• Analyzing historical climate deviations by comparing vim against the vim_lta average
• Identifying localized drought or flood impacts via the viq anomaly percentage

Strengths

• Uses NASA MODIS collection 6.1 high-resolution satellite data
• Includes Pcode references for standardized administrative unit mapping
• Provides n_pixels count to indicate the data density of each aggregate

Limitations

• Geographically restricted to Vietnam sub-national units
• Aggregated format obscures pixel-level spatial variations
• Temporal range start date is not explicitly defined
