You can use our Save GPS Location to Airtable automation for this! Here's how:
Select the table used by your Airtable form
Choose the fields that should hold the latitude and longitude.
Copy and paste the GPS Location URL to your Airtable Form's 'Redirect to URL' setting.
After submitting the Airtable form, users are redirected to a location-sharing page. They must select Share My Location and allow location access in their browser before their latitude and longitude can be saved to the fields you configured.
