Open Data

ODbL 1.0 161,176 RECORDS 61 COUNTRIES

Part of the uMaps atlas is built from OpenStreetMap — the world's open map, made by hundreds of thousands of volunteer mappers. That work is shared under a licence that asks anyone who builds on it to pass the data forward. This page is us doing exactly that.

01Download

The complete OpenStreetMap-derived portion of our database, with the true, unmodified coordinates — no fuzzing, no sign-in, no restrictions.

umaps-osm-derived.json.gz — gzipped JSON, ~5.8 MB compressed (~50 MB raw). Each record carries its originating OSM element id (osm:<type>/<id>), title, description, category, latitude, longitude, and locality.

02Licence and attribution

Location data © OpenStreetMap contributors, available under the Open Database License (ODbL) 1.0. See openstreetmap.org/copyright.

You are free to copy, distribute, adapt and build on this file, including commercially, provided you attribute OpenStreetMap and keep any derived database under the same licence.

03What's in it — and what isn't

Included: named abandoned, ruined and disused places recorded by OSM mappers — derelict buildings, mines and adits, bunkers, ruined chapels, closed institutions, wrecks. Only records with a real name; demolished and under-construction features are excluded, as are roads and waterways. Categories and short descriptions are derived from OSM tags. Every record is unverified by us.

Not included: anything contributed by the uMaps community. Member-submitted sites, access notes, photographs, ratings and visit logs are an independent dataset, are not derived from OpenStreetMap, and are not part of this publication. We deliberately never merge the two, so community contributions stay the community's — and members' own records are governed by our Privacy Policy and Terms of Service.

04Fuzzing, and why the app differs

In the app, public pins are offset within a radius to protect fragile sites. This file is not — the coordinates here are the upstream OSM ones, already public at openstreetmap.org, and the licence is clear that a published derivative database must not be technologically restricted. The two are consistent: the app protects community records; open data stays open.

05Corrections

Found a record that's wrong, sensitive, or shouldn't be mapped? The best fix is upstream at openstreetmap.org, which flows back to everyone. For anything specific to uMaps, email main@efngroup.biz.
