GeoPy

Locating with geocoders

Each geolocation service (like Nominatim) has its own class in geopy.geocoders. (you can write anything in user_agent)

Geocoders each define at least a geocode method, for resolving a location from a string, and may define a reverse method, which resolves a pair of coordinates to an address. For certain locations, you can also change the language (en = English, jp = Japanese).

Calculating Distance

Geopy can calculate geodesic distance between two points with a default of the geodesic distance available as the function geopy.distance.distance.

Reading data with Geocoding

In this code, we will try to get the number of location that is in Sendai city.

We first delay our Geocoding 0.5 second between each address. When the number of data is too many, Geolocator might reject your request. Try to increase the number of second if that happens.

We will be using str accessor, str.contains(), to check whether our string contains a particular substring or not.
