this repo explores challenges faced in accessing electricity my underserved populations in Zambia # Zambia Energy Access Analysis This repository explores challenges faced in accessing electricity by underserved populations in Zambia through comprehensive geospatial analysis and data visualization. ## Overview The project analyzes Zambia's energy infrastructure and population distribution to identify gaps in electricity access. Using population density data, power grid networks, and electrical substations, this analysis provides insights into energy access disparities and potential areas for infrastructure development. ## Project Structure ``` zambia-energy-access-analysis/ │ ├── energy_access.ipynb # Main Jupyter notebook with complete analysis ├── README.md # This file - comprehensive documentation ├── data/ # Directory for storing downloaded data files │ └── (tiff files downloaded during analysis) └── .git/ # Git repository metadata ``` ## Features ### 1. Population Density Analysis - Downloads WorldPop 2020 population data for Zambia - Visualizes population distribution using custom colormap - Applies PowerNorm transformation for better visualization - Identifies population centers and rural areas ### 2. Power Grid Network Mapping - Fetches power lines data from OpenStreetMap via Overpass API - Color-codes transmission lines by voltage levels: - 330kV: Dark red (#c0392b) - 220kV: Orange (#e67e22) - 132kV: Yellow (#f1c40f) - 88kV: Green (#27ae60) - 66kV: Blue (#3498db) - 33kV: Purple (#9b59b6) - 11kV: Pink (#e91e63) ### 3. Electrical Substations Analysis - Maps electrical substations across Zambia - Creates 10km buffer zones around each substation - Visualizes service areas and coverage gaps - Uses EPSG:3395 projection for accurate distance calculations ### 4. Integrated Infrastructure Mapping - Combines all layers into a comprehensive visualization - Shows spatial relationships between population and infrastructure - Identifies underserved areas and infrastructure gaps - Pr …
