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.
