We know location based search is slowly becoming popular and a must have for any content website in the recent era, Drupal 8 needs to have a drop-in solution for geo-spatial search. Right now, there are some alpha modules existing but these modules need some serious investment for them to become production ready.
Search_API_Location module provides the Geo-spatial search experience to Drupal. Geo-spatial search mainly refers to searching data that is associated with a particular location. Currently only D7 supports this feature.
