# 3D Bivariate Climate Maps of Nigeria This project creates both 2D and 3D bivariate climate maps of Nigeria, visualizing the relationship between temperature and precipitation using CHELSA climate data. The 3D visualization incorporates elevation data to provide a more immersive representation of climate patterns across the country. ## Project Overview This repository contains R code for generating bivariate climate maps that simultaneously display two climate variables (temperature and precipitation) in both 2D and 3D formats. The project leverages several R packages to download climate data, process spatial information, and create compelling visualizations. The resulting visualizations help to identify climate patterns and regional variations in Nigeria's climate, showing how temperature and precipitation interact across different geographical areas and elevations. ## Features - **2D Bivariate Map**: A traditional flat map showing the relationship between temperature and precipitation - **3D Visualization**: An interactive three-dimensional representation that incorporates elevation data - **Automated Data Processing**: Code to download and process CHELSA climate data for Nigeria - **High-Quality Outputs**: PNG files optimized for presentations and publications ## Sample Outputs ### 2D Bivariate Climate Map ### 3D Climate Visualization ## Technical Implementation The project is implemented in R and uses the following key packages: - **rchelsa**: For downloading CHELSA climate data - **terra**: For raster data processing - **geodata**: For downloading administrative boundary data - **sf**: For handling spatial vector data - **biscale**: For creating bivariate color scales - **elevatr**: For obtaining elevation data - **rayshader**: For 3D visualization - **ggplot2**: For 2D visualization - **cowplot**: For combining plots and legends ### Data Sources - **Climate Data**: CHELSA v2.1 (Climatologies at high resolution for the earth's land surface ar …
