Podcast episode featuring the Overpass API

Posted by SB79 on 29 December 2012 in German (Deutsch)


if you happen to understand German, I’d like to point you to a recently published podcast episode which features the Overpass API and its developer, Roland Olbricht. “The Overpass API (or OSM3S) is a read-only API that serves up custom selected parts of the OSM map data. 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.” (*)

In this extensive interview, Roland talks about the Overpass query language and its underlying design principles, about the OSM developer community, and about future challenges and ideas (64 bit node IDs, federated databases, permanent IDs, dynamical cleaning of tagging information - to name just a few).
