Geolocation Field

Geolocation Field provides a field type to store geographical locations as pairs of latitude and longitude (lan,lng). The Drupal 8 version also provides a views proximity search plugin. Geolocation Field can be used with all fieldable entities like nodes, users, comments, taxonomy terms, etc.

Geolocation Field aims to provide a light-weight, easy-to-use and robust alternative to more complex solutions.

Drupal 8

The Drupal 8 version of Geolocation Field is a complete rewrite. Please test and open an issue to fix a bug or share your thoughts.

Technical background (Drupal 7/Drupal 8)

At the moment Geolocation stores the following values in the database:

• lat (latitude),
• lng (longitude),
• lat_sin (precalculated latitude sine),
• lat_cos (precalculated latitude cosine),
• lng_rad (precalculated radian longitude).

The precalculated values will speed up proximity SQL look ups.
