I’m pretty sure I know the answer but I’ll ask anyway. I have some Lat/Lng that I’d like to resolve to street addresses on the server side. Is this possible? Is it a reasonable feature request?
The answer is yes, that’s possible!
We have geopy installed in Server Modules (for full package list, see here - we can install any more that you ask for.)
Here’s a simple server function that does a reverse geocode lookup using a free API:
from geopy.geocoders import ArcGIS
@anvil.server.callable
def geocode(lat, lng):
geolocator = ArcGIS()
location = geolocator.reverse((lat, lng))
print(location.address)
You can also do geocoding from the client side using our GoogleMap integration:
addresses = GoogleMap.geocode(location=lat_lng)
print(addresses[0].formatted_address)
Here’s the relevant section of the reference docs.
Here’s an app that prints the address when you click on a map:

(Note: The results differ slightly depending on which API you use, and most APIs give you a list of nearby addresses to choose from.)

is this broken? I am using the basic account and have followed the code here and I am met with the below when clicking on the map:
ExternalError: Geocode failed: REQUEST_DENIED
Is there a limitation here that the docs aren’t covering?
(EDIT: To specify I am using the GoogleMaps integration on client side)
