Description
Guinea sub-national vegetation health is tracked via dekadal NDVI indicators derived from NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme, the data includes 10-day averages, long-term averages, and percentage anomalies. The records are aggregated by administrative units using WFP-standardized Pcode references.
Use Cases
Monitoring agricultural health by comparing current NDVI (vim) against long-term averages (vim_lta)
Identifying drought conditions using the NDVI anomaly percentage (viq)
Assessing the reliability of regional aggregates using the n_pixels count
Strengths
Uses NASA MODIS collection 6.1 high-quality satellite imagery
Includes historical baselines via the vim_lta column for longitudinal comparison
Provides Pcode references for integration with WFP administrative boundaries
Limitations
Aggregated at the sub-national level, masking local variations within administrative units
Temporal frequency is limited to 10-day dekads
Provenance
Source
World Food Programme (WFP) via NASA MODIS
Collection Method
Satellite sensor data aggregation from NASA Aqua and Terra satellites
Freshness
Updated as of March 2026.
Geography

Users will need WFP administrative boundary shapefiles to map the Pcode references provided in the data.
