Where to Find City Elevation Data

Reliable sources for city elevations above sea level:

• NOAA (US): coastal elevation data.
• USGS (US): National Elevation Dataset.
• Wikipedia (global): List of cities by elevation.
• Google Maps: Search city → Terrain layer → elevation shown bottom-left.

For precise survey data, consult national mapping agencies (e.g., USGS, Ordnance Survey UK, IGN France).
