Return bad results from MapsSearchClient::get_reverse_geocoding()

[JohnMiner3]

• Package Name: azure.maps.search
• Package Version: latest
• Operating System: Windows
• Python Version: 3.12.7

Describe the bug

I wrote a function to geocode a location given an address using the library. That works fine. But if I reverse geocode a location it returns the wrong address.

To Reproduce
Steps to reproduce the behavior:

1. Run the code at the bottom in a Jupyter notebook. It looks like about 41 pct of the reverse lookups are wrong. See image below.

2. This code was test on a Databricks cluster also with the same results. I had a total of 234 sample addresses.

Expected behavior

This is basic math. x = sqrt(sqr(x))

The same should be with the maps functions. a = reverse-geocode(geocode(a))

Screenshots

Bad reverse lookup.

Using another tool comes up with correct location.

Additional context

The python function output shows what is wrong. If we geocode an address to get coordinates. The reverse geo-code of those coordinates should produce the same result.

Test Maps Search Client

from azure.core.credentials import AzureKeyCredential
from azure.maps.search import MapsSearchClient
api_key = "<your key here>"

def get_additional_address_info(api_key, raw_address):

# create object
azmaps = MapsSearchClient(credential=AzureKeyCredential(api_key))

# initialize variables
longitude = 0.0
latitude = 0.0
address = {'formattedAddress': '', 'postalCode': ''}
coordinates = [0.0, 0.0]

# Perform geocoding
try:
    retval1 = azmaps.get_geocoding(query=raw_address)

    if retval1.get('features'):
        coordinates = retval1['features'][0]['geometry']['coordinates']
        print(coordinates)
        longitude, latitude = coordinates

except Exception as e:
    pass

# Reverse geocoding  
try:
    retval2 = azmaps.get_reverse_geocoding(coordinates=coordinates)

    if retval2.get('features'):
        address = retval2['features'][0]['properties']['address']

except Exception as e:
    pass

return { "address": address['formattedAddress'], "postalCode": address['postalCode'], "longitude": longitude, "latitude": latitude }

Test function

raw_address = "780 Lynnway, Lynn, MA, United States 01905"
retval3 = get_additional_address_info(api_key, raw_address)
print(retval3)
