Population Density Map of Alexandria

This project visualizes population density in Alexandria using spatial data processing in R. The analysis leverages GIS techniques to read, transform, and map geospatial data.

Features

• Reads and processes a TIFF file containing population density data.
• Converts raster data to an sf object for spatial analysis.
• Creates a percentile-based color map using the viridis color palette.
• Overlays administrative boundaries from a shapefile.
• Adds labeled regions for better readability.

Requirements

Ensure the following R packages are installed:

install.packages(c("sf", "tidyverse", "viridis", "stars", "ggrepel"))

Data Files

• Alexandria_population.tif: Population density raster file.
• Alexandria.shp: Shapefile containing administrative boundaries.

Usage

Run the R script to generate the population density map:

source("Alexandria_Population_Map.R")

Output

Initial SF Object Plot

The default plot of an sf object shows multiple attributes:

Final Population Density Map

The final output map, enhanced with boundaries and labels:
