Description
Benin's sub-national vegetation health is tracked in this dataset via dekadal (10-day) NDVI indicators derived from NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme, the data aggregates pixel-level observations into administrative units to provide current values, historical averages, and anomalies.
Use Cases
Assessing drought impact by analyzing the `viq` anomaly percentage across different Pcode regions
Comparing seasonal vegetation trends using the `vim` and `vim_lta` columns
Evaluating data reliability per administrative unit using the `n_pixels` count
Strengths
Uses NASA MODIS collection 6.1 high-quality satellite data
Includes historical baselines via the `vim_lta` column
Standardized Pcode references for administrative unit alignment
Limitations
Spatial resolution is limited to administrative aggregates rather than raw pixels
Data quality in specific dekads may be impacted by cloud cover affecting the `n_pixels` count
Provenance
Source
World Food Programme (WFP) via NASA MODIS
