Feature Overview
Geocoding is the process of converting addresses like "1600 Amphitheatre Parkway, Mountain View, CA" into geographic coordinates like latitude 37.423021 and longitude -122.083739.
The Geocoding node is an Add In node that allows users to convert addresses within their data that can then be used to place markers on a map, or position a map. This node makes use of either Census, Google or Geocodio free address validation and conversion APIs. These APIs not only generate the exact coordinates for all addresses, but also can help to clean up and reformat address data.
Note: There is a function feature within the Transform node that can generate corresponding latitude/longitude coordinates from zip codes. However, this would be a general location rather than a specific street address.
| API Feature | Information |
| Census API | Default selection. No registration necessary. No limitation on records. |
| Google API | Account required and API key necessary. Limitation of 2, 500 records per day. |
| Geocodio API | Account required and API key necessary. Limitation of 2,500 records per day. |
Important: While Google and Geocodio are free applications, both APIs limit the number of requests to 2,500 queries per day. This means you can submit 2,500 rows of data per day for validation. Exceeding this amount will result in the error below:
