evy is a Python package for fetching, processing, and analyzing Enhanced Vegetation Index (EVI) data from MODIS satellite imagery. It provides a high-level interface to work with vegetation data, enabling researchers and practitioners to monitor vegetation health, compute phenological metrics, and perform zonal statistics with ease.
Note: This package is a work in progress. Features and APIs may change as development continues.
- Easy Data Access: Fetch MODIS EVI data from Planetary Computer with automatic quality masking
- Zonal Statistics: Compute statistics (mean, median, max, etc.) for specific geometries
- Temporal Aggregation: Aggregate data at various temporal frequencies (monthly, yearly, quarterly)
- Phenology Analysis: Extract and visualize vegetation growing seasons and phenological patterns
- Land Cover Masking: Filter EVI data by land cover classification (e.g., cropland-only analysis)
- Visualization: Built-in plotting functions for time series and phenology
