Interactive national map of humanitarian access at woreda (admin3) level for Ethiopia, with OSM health facilities and status-change layers. # Ethiopia Humanitarian Access Map An interactive national map of humanitarian access at **admin3 (woreda)** level for Ethiopia, overlaid with **OpenStreetMap health facilities** and a **facility status-change** layer. **Live map:** aschroedercr.github.io ## What the map shows - **Access choropleth** for all **1,148 woredas**, on a green→red humanitarian ramp (Accessible → Partially accessible → Some restrictions of movement → Hard to reach), with a layer toggle to switch between **December 2025 / February 2026 / April 2026**. - **Health facilities (OSM)** — 1,148 facilities classified as Hospital / Clinic / Pharmacy / Other, clustered at national zoom and de-clustered into individual color-coded markers when you zoom in. - **Facility status changes (Dec–Apr)** — the 95 facilities whose woreda access category changed over the three months, colored by direction (deteriorated / improved / transient), each with a popup showing its Dec → Feb → Apr path. ## Data sources | Layer | Source | |---|---| | Woreda access status | ETC national access map data, April 2026 (`eth_national-access-map-data_-april-2026.xlsx`) | | Admin3 boundaries | OCHA COD-AB Ethiopia v04 (valid 2025-01-01), from HDX | | Health facilities | HOTOSM / OpenStreetMap Ethiopia health facilities | ## Reproducing the map The published `index.html` is self-contained. To regenerate it: 1. Install dependencies: `pip install pandas geopandas folium shapely openpyxl` 2. Place the source files in the project root: - `eth_national-access-map-data_-april-2026.xlsx` - `cod_boundaries/eth_admin3.shp` (+ sidecars) — download the SHP package from the OCHA COD-AB dataset and extract into `cod_boundaries/` - `health_facilities/health_facilities.geojson` — from the HOTOSM export 3. Run: `python build_access_map.py` This writes `ethiopia_access_map.html` (copied to `index.html` for Pages). ## Notes - Facilities are assigned to woredas by **spatial join against full-resolution b …
