Guadeloupe Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Dekadal NDVI indicators for Guadeloupe derived from NASA MODIS satellite imagery and aggregated by the World Food Programme (WFP). The data tracks vegetation health through 10-day indices, historical averages, and anomalies at the sub-national administrative level.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against the long-term average (vim_lta)
• Identifying drought or vegetation stress using the NDVI anomaly percentage (viq)
• Validating data reliability for specific regions using the n_pixels count

Strengths

• Uses NASA MODIS collection 6.1 high-resolution satellite data from both Aqua and Terra
• Includes long-term averages (vim_lta) for historical baseline comparison
• Standardized Pcode references for integration with other WFP datasets

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel-level data
• Total record count and specific historical range are not explicitly defined in the metadata
