Geocoding Using Geopy And Python

December 23, 2023 Post a Comment

I am trying to Geocode a CSV file that contains the name of the location and a parsed out address which includes Address number, Street name, city, zip, country. I want to use GEOP

Solution 1:

I've been using this script to do some batch-geocoding from .csv. It requires that one column contain the complete text address that you wish to geocode, and that one column be titled 'UniqueID', which has a unique identifier for each item in the .csv. It will also print out a list of any addresses that it failed to geocode. It also does a quick check to see if the zip code might be incorrect/throwing off the geocoding:

defmain(path, filename):
# path to where your .csv lives, and the name of the csv.import geopy
    from geopy.geocoders import ArcGIS
    import pandas as pd

    Target_Addresses = pd.read_csv(path+'\\'+filename)
    Target_Addresses['Lat'] = np.nan
    Target_Addresses['Long'] = np.nan
    Indexed_Targets = Target_Addresses.set_index('UniqueID')

    geolocator = ArcGIS() #some parameters here
    Fails = []
    for index, row in Indexed_Targets.iterrows():
        Address = row['Address']
        Result = geolocator.geocode(Address)
        if Result == None:
            Result = geolocator.geocode(Address[:-7])
            if Result == None:
                Fails.append[Address]
            else:
                Indexed_Targets.set_value(index, 'Lat', Result.latitude)
                Indexed_Targets.set_value(index, 'Long', Result.longitude)
        else:
            Indexed_Targets.set_value(index, 'Lat', Result.latitude)
            Indexed_Targets.set_value(index, 'Long', Result.longitude)
    for address in Fails:
        print address
    Indexed_Targets.to_csv(filename[:-4]+"_RESULTS.csv")

if __name__ == '__main__':
    main(path, filename) # whatever these are for you...

This will output a new csv with "_RESULTS" (e.g., an input of 'addresses.csv' will output 'addresses_RESULTS.csv') with two new columns for 'Lat' and 'Long'.

Solution 2:

this is just a beggining, tell me if that helps. It does not write to the csv but I'll edit my answer later if you need that part also
