Osm2pgsql imports OpenStreetMap (OSM) data into a PostgreSQL/PostGIS database. It is an essential part of many rendering toolchains, the Nominatim geocoder and other applications processing OSM data.
- Flexible configuration
Clean up and convert the OSM data in any way you like before importing into the database. Database table names, column structure, data types, can all be configured the way your application or style needs it.
- Stay up-to-date with OSM
An osm2pgsql database can be updated from OSM change files. If you want to, you can keep your database current with only a few minutes delay from the main OSM database.
- Valid Geometries
Osm2pgsl creates point, line, polygon, and multipolygon geometries from OSM data and makes sure they are always valid.
Osm2pgsql is a command line program written in portable C++. It works on Linux, Windows, and macOS.
- Many OSM input formats
Process OSM files of any type (in XML, PBF, or O5M format).
- Any Projection
Import geometries in Lon/Lat (WGS84), Web Mercator (most popular format for map tiles), or any other projection.
- Support for hstore and JSON
Use hstore and JSON(B) PostgreSQL data types to store the complete set of tags of an OSM object in a single database column.
- Resource friendly
You can run a database with all OpenStreetMap data for the whole planet on a single, reasonable-sized machine.
These examples show some use cases of osm2pgsql and highlight some features.
This is the "classical" job of osm2pgsql: Import OSM data into a database to create raster tiles from.
Osm2pgsql imports OSM data using a very flexible configuration making it easy to generate any kind of vector tiles.
The Nominatim Geocoder uses osm2pgsql for the import of OSM data. It adds its own postprocessing to create the special data structures needed for geocoding.
Need only a few feature types? Import only what you need for a quick map.
Osm2pgsql can use many different projections to fit the area covered and your use case.
An osm2pgsql database is well-suited for geospatial analysis using the power of the PostGIS database extension.
Exporting OSM Data
Osm2pgsql and a database can be used as a step in exporting OSM data into many different GIS formats.
Developing and supporting osm2pgsql takes a huge amount of effort. We thank the following companies and organizations for their support:
