Environmental Data Preparation for Cholera Ecological Niche Modeling Objectives of Data Preparation Before running the ecological niche model (ENM), we must:✅ Load and preprocess environmental raster data (NetCDF format).✅ Compute average climate conditions across multiple time periods.✅ Remove problematic variables (NA values, zero-inflated layers).✅ Standardize and scale climate predictors for modeling consistency.✅ Mask climate data to the study region for spatial relevance.

This script performs an ecological niche modeling (ENM) analysis for Cholera, utilizing hypervolume analysis to understand its environmental niche based on climate conditions. The study follows a structured workflow integrating occurrence data, environmental predictors, and advanced modeling techniques to project potential Cholera distributions under current and future climate scenarios.
