Geolocation guides

How to scope PredictHQ queries to the places your business cares about.

The recommended pattern is one setup step: create a Saved Location from a lat/lon origin and let Predicted Impact Area calculate the boundary where events actually affect that location - then reference the location_id everywhere. The guides in this section cover the underlying mechanics when you need them: searching by location, place hierarchies, polygons, and joining events with Placekey.

Avoid hand-picked fixed radii - they include irrelevant events and miss relevant ones. See the overview for how the location methods compare.
