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 <a href="http://wiki.openstreetmap.org/wiki/Nominatim" rel="nofollow ugc">OSM Nominatim</a> 
geocoder enabled by default and supports <a href="https://geocod.io/" rel="nofollow ugc">Geocod.io</a> 
and the <a href="https://developers.google.com/maps/" rel="nofollow ugc">Google Maps API</a> 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..
<h4>What is Geocoding?</h4>
<a href="https://en.wikipedia.org/wiki/Geocoding" rel="nofollow ugc">Geocoding</a> 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.
<h4>Support for Other Geocoders</h4>
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.

A spatial foundation for WordPress. Store and search spatial metadata like you do any other metadata, but using MySQL spatial indexes.
WP GeoMeta lets you take advantage MySQL’s spatial data types and spatial indexes when storing and searching spatial metadata.
It detects when <a href="http://geojson.org/" rel="nofollow ugc">GeoJSON</a> metadata is being stored, and transparently stores a copy in a spatial meta table.
WP GeoMeta also adds support for spatial search operators. When a spatial search operator is used, WP GeoMeta will make sure that the spatial table is used, taking advantage of indexes and spatial relations.
WP GeoMeta isn’t just a plugin, it’s also a library which other plugins can take advantage of. It’s meant to be a spatial platform that other GIS and mapping plugins can build on to allow spatial interoperability between plugins.
<h3>Developers</h3>
WP-GeoMeta is tested and developed in the open over at <a href="https://github.com/BrilliantPlugins/wp-geometa" rel="nofollow ugc">GitHub</a>. Stable versions are pushed to the WordPress plugin repository.
There is more developer documentation in the GitHub repository and I’d love to get pull requests and bug reports over there (but I’ll take them via SVN too if that’s what you like better).

Love how this plugin handles spatial data automatically, and integrates with Advanced Custom Fields!

Awesome plugin, wish it was in core!

This plugin deserves more kudos it is fantastic, although more beneficial if you are on mysql 5.7 or greater.

Great plugin

Store and search spatial metadata like any other metadata, but while taking advantage of MySQL spatial types and indexes.
