Address geocoder

The Address geocoder tool lets you upload a CSV and fill missing coordinate values by geocoding addresses.

What you’ll need

• A CSV file containing:
  • either a single address column, or
  • an address column plus optional latitude / longitude columns
• An API key for one of:
  • Azure Maps
  • Google Maps

Step-by-step

1. In the portal, open Tools → Address geocoder
2. Choose your provider (Azure Maps or Google Maps)
3. Paste your API key
4. Upload or drag-and-drop your CSV
5. Map the columns (address / latitude / longitude) if prompted
6. Click Geocode to generate an output CSV

Supported CSV shapes

The tool is flexible about input shape:

• Addresses only
  • one column
  • with or without a header row
• Address + latitude + longitude
  • three columns
  • with or without headers

The tool will always output all original columns, plus latitude / longitude columns that are added or updated as required.

Output

• Output is a CSV download.
• The output preserves the full input file (all columns).
• Latitude/longitude values are written into the mapped columns when present; otherwise new columns are added.

Provider notes

Azure Maps

• Use an Azure Maps subscription key.
• If you see CORS errors in the browser console, ensure your Azure Maps account has allowed origins configured for your portal domain (and http://localhost[:port] for local testing).

Google Maps

• The tool uses the Google Maps JavaScript API geocoder (browser-friendly) rather than the Google web service endpoints.
• Ensure your Google Cloud project has billing enabled and the required Maps APIs enabled for your key.
