Lao PDR Subnational NDVI Vegetation Indicators and Anomalies

Dekadal NDVI vegetation indicators for Lao People's Democratic Republic, aggregated from NASA MODIS satellite imagery by the World Food Programme. It contains 10-day vegetation indices, long-term averages, and anomalies mapped to sub-national administrative units. The data is derived from NASA's Moderate Resolution Imaging Spectroradiometer collection 6.1.

Use Cases

• Analyzing agricultural drought trends by comparing vim against vim_lta
• Identifying regional vegetation stress using the viq anomaly percentage
• Correlating vegetation health with food security using WFP Pcode identifiers

Strengths

• Derived from NASA MODIS collection 6.1 (Aqua and Terra) sensors
• Includes standardized WFP Pcode references for administrative unit joins
• Provides pixel counts (n_pixels) to indicate data density per unit

Limitations

• Aggregated at the sub-national level, losing fine-grained spatial variance within units
• Optical sensor data is susceptible to cloud cover interference in tropical regions
