A fast, offline Python library for reverse geocoding that converts latitude/longitude coordinates into the nearest city, country code, and administrative regions. It uses a parallelised K-D tree implementation over GeoNames city data and supports custom CSV data sources.

Use cases

• convert gps coordinates to city name offline
• reverse geocode lat lon in python without internet
• find nearest city to a coordinate
• get country code and admin region from coordinates
• bulk reverse geocoding of large coordinate datasets
• use custom city database for reverse geocoding

When to choose

• you need offline reverse geocoding with no API calls
• you need fast nearest-neighbor lookups over large coordinate batches
• you want administrative region data alongside city and country
• you want to plug in your own CSV place database

When to avoid

• you need forward geocoding (address to coordinates)
• you need precise street-level or address-level results
• you need an actively developed project with recent updates
• you need a web service or API rather than a Python library
