Polars-Reverse-Geocode
Polars plugin based on https://github.com/gx0r/rrgeo.
rrgeo takes a latitude and longitude as input and returns the closest city, country, latitude, and longitude, using a k-d tree to efficiently find the nearest neighbour based on a known list of locations. This can be useful if you need to reverse geocode a large number of coordinates quickly, or just need the rough location of coordinates but don't want the expense or complication of an online reverse geocoder.
Installation
pip install polars-reverse-geocode
Usage example
import polars as pl
from polars_reverse_geocode import find_closest_city
df = pl.DataFrame({
'lat': [37.7749, 51.01, 52.5],
'lon': [-122.4194, -3.9, -.91]
})
print(df.with_columns(city=find_closest_city('lat', 'lon')))
shape: (3, 3)
