PostGIS vs Elasticsearch geo: which is better for search + maps?

PostGIS wins for spatial analysis and precise geographic relationships tied to relational data, while Elasticsearch wins for fast geo-filtered full-text search across large document sets. PostGIS has been in production since 2001 and implements the OGC Simple Features for SQL specification, giving it a standardized set of geometry types and spatial operators that Elasticsearch does not attempt to match.

How do the two actually differ?

When does PostGIS fit better?

PostGIS is the right choice when the application needs true spatial analysis: finding which polygon a point falls inside, computing route distances along a network, running buffer or intersection operations, or joining geographic data directly against other relational tables in the same query. Because it runs inside PostgreSQL, a single transaction can combine spatial logic with ordinary business data without exporting anything to a separate system.

When does Elasticsearch fit better?

Elasticsearch fits when the primary need is searching large volumes of documents by text and narrowing results with a location filter, such as restaurants matching a keyword within a two mile radius. Its geo_point and geo_shape types support geo-distance and geo-bounding-box queries, but the geometry model is intentionally simpler than PostGIS and is not built for deep spatial analytics like topology checks or polygon overlays.

Which one should a team actually pick?

Teams building GIS platforms, logistics or routing tools, or anything doing serious spatial math should hire for PostGIS and PostgreSQL experience. Teams building search-heavy products such as marketplaces or directories, where location is one filter among many, should lean on Elasticsearch. Many production systems run both: PostGIS as the system of record for spatial data, Elasticsearch as the search layer synced from it.
