Questions tagged [overpass-api]

The Overpass API (or OSM3S) is a read-only API that serves up custom selected parts of the OpenStreeetMap map data.

The Overpass API (or OSM3S) is a read-only API that serves up custom selected parts of the OpenStreeetMap map data (elements and tags) via a specifically crafted query language. It acts as a database over the web: the client sends a query to the API and gets back the data set that corresponds to the query.

Unlike OSM's main API, which is optimized for editing, Overpass API is optimized for data consumers that need a few elements within a glimpse or up to roughly 100 million elements in some minutes, both selected by search criteria like e.g. location, type of objects, tag properties, proximity, or combinations of them. It acts as a database backend for various services.

The overpass turbo frontend allows to interactively run Overpass API queries and analyze the resulting data on a map.
