Guatemala Subnational NDVI: 10-Day Vegetation Indices and Anomalies

Supplying dekadal NDVI indicators for Guatemala 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 indices, historical averages, and percentage anomalies updated as recently as March 2026.

Use Cases

• Monitoring agricultural health by comparing current vim against vim_lta across different dekads
• Identifying drought-affected regions using the viq anomaly percentage column
• Correlating vegetation density with food security outcomes by joining Pcode references to socioeconomic data

Strengths

• Uses NASA MODIS collection 6.1 high-resolution satellite data from both Aqua and Terra
• Includes vim_lta for direct historical baseline comparison
• Provides n_pixels to indicate the statistical weight and reliability of each aggregate

Limitations

• Aggregated at the sub-national level, which obscures granular pixel-level spatial variance
• Dependent on WFP administrative boundary definitions which may not align with other government or international standards
