Batch geocode in Azure map

Balasaheb Molawade 141

Hi Team,

We are currently using the batch processing functionality of Bing Maps as outlined in the link below: https://blogs.bing.com/maps/2022-10/Batch-Geocoding-and-Batch-Reverse-Geocoding-with-B-8ab099cf6fda90a4fbdca761af8bbdca

We would like to implement similar batch processing capabilities using Azure Maps. If anyone has sample code, guidance, or reference implementations for this functionality, please share it with us.

Thank you in advance for your support.

Thanks!

You would most likely want to use this Azure Maps batch geocoding service: https://dotnet.territoriali.olinfo.it/en-us/rest/api/maps/search/get-geocoding-batch?view=rest-maps-2025-01-01&tabs=HTTP

You basically create a JSON file and post it to the service. It looks like this service is currently only synchronous (send a request, get a response with not extra steps needed in between), and as such is limited to 100 items per request.

Hi Ricky,

Thank you for your response. We will review the details shared and proceed with the implementation accordingly.

Please let us know if any further information is required from our side.

Thanks!

Hi Ricky,

Do you have any sample code available for this functionality.

Additionally, we would like to understand how we can geocode thousands of records at once, instead of being limited to batches of 100 records. Please let us know if there is a recommended approach or best practice for handling bulk geocoding at scale.

Looking forward to your guidance.

Thanks!

Have you looked at the Azure Maps Sample site for code samples? https://samples.azuremaps.com/services-module/methods-for-geocoding-multiple-addresses

Hi,

Thank you for your response. We will review it from our end.

In the meantime, could you please share any available C# sample code for this scenario, if possible?

Looking forward to your response.

Thanks!

There is a code sample in the documentation for the C# nuget library for Azure Maps here: https://dotnet.territoriali.olinfo.it/en-us/azure/azure-maps/how-to-dev-guide-csharp-sdk

To process thousands of addresses you will need to make multiple requests. Note that there wouldn't be any cost difference compared to passing all the addresses in a single request and it is highly likely that making multiple smaller parallel requests will be much faster.

Hi Ricky,

We are using the Azure Maps Geocoding Batch API as referenced in the link below: https://dotnet.territoriali.olinfo.it/en-us/rest/api/maps/search/get-geocoding-batch?view=rest-maps-2025-01-01&tabs=HTTP

We have tested geocoding by processing records in batches of 100. This approach works as expected for smaller datasets; however, when the number of records increases to approximately 100,000, the overall processing time becomes significantly longer.

We understand that there may be a possibility to submit batch geocoding requests asynchronously. We have reviewed the available documentation but were unable to find a clear example or reference implementation for handling asynchronous batch geocode requests at this scale.

Could you please let us know if you have any recommended approach, sample code, or best practices for sending and managing asynchronous batch geocoding requests using the Azure Maps API?

We look forward to your guidance on this.

Thanks!

I don't believe asynchronous batches are available currently in the latest batch geocoding service (only the older v1 service that's less accurate). You can however make multiple parallel requests. Looking at the default limits on queries per second for Azure Maps, you can make 10 queries to the batch geocoding service every second (https://dotnet.territoriali.olinfo.it/en-us/azure/azure-maps/azure-maps-qps-rate-limits). To process 100,000 addresses, you would make 1000 requests, with up to 10 requests made every second. This would take 100 seconds (1m 40s) to request all the addresses (likely a bit longer to when handling all the responses.

If you are using the C# REST library for Azure Maps, you can create 10 instances of the MapsSearchClient, and spread the data across this. A simple example would be to say client 1 will processes addresses 0 to 9,999, and will step through the data, 100 records at a time, while client 2 will process addresses 10,000 to 19,999, and so on.
