PyAEZ is a python package consisted of many algorithms related to Agro-ecalogical zoning (AEZ) framework. PyAEZ tries to encapsulate all complex calculations in AEZ and try to provide user friendly, and intuitive ways to input data and output results after calculations.

PyAEZ includes 5 main modules as below. Additionally to that, UtilityCalculations module is also included in PyAEZ to perform additional related utility calculations.

• Module I: Climate Regime
• Module II: Crop Simulations
• Module III: Climate Constraints
• Module IV: Soil Constraints
• Module V: Terrain Constraints
• UtilityCalculations Module

Other than 5 main modules and utility module, following 3 major algorithms related to AEZ also are included in PyAEZ. Those 3 major algorithms can be utilized individually without running whole PyAEZ.

• Biomass Calculations
• Evapotranspiration Calculations
• CropWat Calculations

• numpy
• scipy
• gdal

Following 5 Jupyter notebooks in the repository can be used as worked full example for PyAEZ 5 major modules.

• NB1_ClimateRegime.ipynb
• NB2_CropSimulation.ipynb
• NB3_ClimaticConstraints.ipynb
• NB4_SoilConstraints.ipynb
• NB5_TerrainConstraints.ipynb

API Documentation is located in "docs" folder.
