Description
Delivering dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for Slovakia, aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme (WFP), the records include current vegetation metrics, long-term averages, and percentage anomalies. The data is structured to support environmental monitoring at the regional level using standardized WFP Pcode references.
Use Cases
Monitoring agricultural health by comparing current vim against the long-term average vim_lta
Identifying regional drought conditions using the viq anomaly percentage
Validating environmental models using the n_pixels count to weight data reliability
Strengths
Uses NASA MODIS collection 6.1 high-resolution satellite imagery
Includes n_pixels column to indicate the data density and reliability of each aggregate
Provides vim_lta for direct historical baseline comparisons
Limitations
Aggregated at the sub-national level, which may mask localized vegetation changes within a specific unit
Satellite-derived NDVI is sensitive to cloud cover interference which can affect data quality in specific dekads
