French Guiana Subnational NDVI: Dekadal Vegetation Indices and Anomalies

A source of dekadal NDVI indicators for French Guiana, aggregated from NASA MODIS collection 6.1 satellite imagery by the World Food Programme. It tracks vegetation health through 10-day indices, long-term averages, and anomalies mapped to sub-national administrative units.

Use Cases

• Analyzing vegetation health trends using the vim (10-day NDVI) column
• Detecting environmental stress by monitoring the viq (NDVI anomaly) percentage
• Establishing baseline vegetation levels using the vim_lta (long term average) field

Strengths

• Standardized Pcode references for administrative unit mapping
• Derived from NASA MODIS collection 6.1 Aqua and Terra sensors
• Includes n_pixels column to quantify the data density of each aggregate

Limitations

• Spatial resolution is limited to sub-national administrative aggregates
• Geographic scope is restricted to French Guiana
