Description
Satellite-derived vegetation indicators for Costa Rica are provided at the sub-national level using NASA MODIS collection 6.1 data from Aqua and Terra sensors. Produced by the World Food Programme (WFP), the dataset tracks 10-day NDVI, long-term averages, and anomalies across administrative units. The records are structured for humanitarian monitoring and include pixel counts for each aggregated area.
Use Cases
Monitoring agricultural health by comparing current `vim` against the long-term average `vim_lta`
Identifying drought or stress periods using the `viq` anomaly percentage
Validating the statistical significance of regional aggregates using the `n_pixels` count
Strengths
Uses NASA MODIS collection 6.1 data from both Aqua and Terra satellites
Includes `n_pixels` column to quantify the data density behind each administrative aggregate
Standardized with WFP Pcode references for interoperability with other humanitarian datasets
Limitations
Spatial resolution is limited to sub-national administrative units rather than raw pixel grids
Data quality in tropical regions can be affected by persistent cloud cover during satellite overpasses
