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.
