WordPress does not include any geographic functionality or functions to deal with Geodata itself (something that might be called a Geodata API). But there is a standard for how to store geodata, so that plugins can interoperate.

Where to store Geodata ?

Geodata for an object should be stored in the metadata for that object.

• Geodata for posts, pages and other post-types should be stored in postmeta.
• Geodata for users should be stored in usermeta.
• Geodata for comments should be stored in commentmeta.
• Geodata for terms should be stored in termmeta.

Geodata Format

Meta keys and their meta values are listed below.

geo_latitude REQUIRED

(float) decimal degrees -90 to 90 (negative values are in the southern hemisphere).

geo_longitude REQUIRED

(float) decimal degrees -180 to 180 (negative values are in the western hemisphere).

geo_public OPTIONAL

(int) is the geodata public (1) or private (0)? If value is missing or not set to 0, assume public.

geo_address OPTIONAL

(string) freeform textual description of coordinates.

"221B Baker St, Westminster, London NW1 6XE, UK",

"Pasadena, CA", "Soho, NYC", "Idaho", etc.

Accuracy level and language is arbitrary.
