PyAEZ

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.

Introduction

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

Dependencies

numpy
scipy
gdal

Step-by-step Process

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