MODIS Terra EVI Phenology Annual 250m Grid

MODIS/Terra EVI Phenology annual L4 250m SIN Grid provides gap-filled, smoothed Enhanced Vegetation Index (EVI) data derived from 8-day surface reflectance composites. The dataset is produced by the LAADS organization and is stored in Hierarchical Data Format (HDF) with a sinusoidal projection. Its presence on multiple authoritative platforms indicates its established use in the remote sensing community.

Use Cases

• Tracking annual vegetation growth cycles using the gap-filled Smoothed EVI layer.
• Monitoring land surface changes over time with 250-meter spatial resolution data.
• Studying phenological metrics like start-of-season and end-of-season derived from the EVI time series.
• Integrating with other MODIS land products for comprehensive land cover analysis due to shared sinusoidal projection.

Strengths

• Provides gap-filled and smoothed data, reducing noise common in raw satellite imagery.
• Offers a consistent 250-meter spatial resolution suitable for regional-scale analysis.
• Uses a standardized sinusoidal projection compatible with other MODIS land products.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on license details, with some listing 'other-license-specified' and others 'None'.
• The temporal coverage (start and end years) for the data is not specified.
