Brilliant Geocoder for Gravity Forms

Brilliant Geocoder for Gravity Forms is a powerful and flexible geocoder field
for Gravity Forms. The Geocoder field is easily be configured to capture geocoder
input values from other form fields.

It comes with the OSM Nominatim
geocoder enabled by default and supports Geocod.io
and the Google Maps API once you’ve entered
API keys for those services.

The geocoder field can be displayed as a map, as latitude and longitude
fields, as the raw GeoJSON data, or hidden.

This plugin supports WP-GeoMeta, so if you create posts or users with geocoded
data, their location will be stored as spatial metadata.

NOTICE: This plugin uses 3rd party services to provide geocoding results.
The default geocoder, OSM Nominatim, requests that you include your email address
in API calls if you are making a large number of requests. We send the WP admin
email address by default. You can change what is sent on the Gravity Forms settings
page, under Geocoder..

What is Geocoding?

Geocoding is the process of turning
text (an address) into coordinates (latitude and longitude). With coordinates
you can display data on a map and do location based searching.

Support for Other Geocoders

Brilliant Geocoders for Gravity Forms includes hooks so that you can add
support for other geocoding services.

OSM Nominatim support is built into the plugin, but Geocod.io and Google Maps
API support is written the same way that you would add support for another
service. The Geocod.io example in particular has extensive comments.

Please see geocoders/geocodio.php and geocoders/geocodio.js for details.
