osm2pgsql [Options] OSM-FILE...

osm2pgsql imports OpenStreetMap data into a PostgreSQL/PostGIS database. It is an essential part of many rendering toolchains, the Nominatim geocoder and other applications processing OSM data.

osm2pgsql can run in either “create” mode (the default) or in “append” mode (option -a, --append).

In “create” mode osm2pgsql will create the database tables required by the configuration and import the OSM file(s) specified on the command line into those tables. Note that you also have to use the -s, --slim option if you want your database to be updatable.

In “append” mode osm2pgsql will update the database tables with the data from OSM change files specified on the command line.

This man page can only cover some of the basics and describe the command line options. See the Osm2pgsql Manual (https://osm2pgsql.org/doc/manual.html) for more information.

This program follows the usual GNU command line syntax, with long options starting with two dashes (--). Mandatory arguments to long options are mandatory for short options too.

-a,  --append

Run in append mode. Adds the OSM change file into the database without removing existing data.

-c,  --create

Run in create mode. This is the default if -a, --append is not specified. Removes existing data from the database tables!

-h,  --help

Print help. Add -v, --verbose to display more verbose help.

-V,  --version

Print osm2pgsql version.

--log-level=LEVEL

Set log level (`debug', `info' (default), `warn', or `error').

--log-progress=VALUE

Enable (true) or disable (false) progress logging. Setting this to auto will enable progress logging on the console and disable it if the output is redirected to a file. Default: true.

--log-sql

Enable logging of SQL commands for debugging.

--log-sql-data

Enable logging of all data added to the database. This will write out a huge amount of data! For debugging.

-v,  --verbose

Same as --log-level=debug.

-d,  --database=NAME

The name of the PostgreSQL database to connect to. If this parameter contains an = sign or starts with a valid URI prefix (postgresql:// or postgres://), it is treated as a conninfo string. See the PostgreSQL manual for details.

-U,  --username=NAME

Postgresql user name.

-W,  --password

Force password prompt.

-H,  --host=HOSTNAME

Database server hostname or unix domain socket location.

-P,  --port=PORT

Database server port.

--schema=SCHEMA

Default for various schema settings throughout osm2pgsql (default: public). The schema must exist in the database and be writable by the database user.

-r,  --input-reader=FORMAT

Select format of the input file. Available choices are auto (default) for autodetecting the format, xml for OSM XML format files, o5m for o5m formatted files and pbf for OSM PBF binary format.

-b,  --bbox=MINLON,MINLAT,MAXLON,MAXLAT

Apply a bounding box filter on the imported data. Example: --bbox -0.5,51.25,0.5,51.75

-i,  --tablespace-index=TABLESPC

Store all indexes in the PostgreSQL tablespace TABLESPC. This option also affects the tables created by the pgsql output. This option is deprecated. Use the --tablespace-slim-index and/or --tablespace-main-index options instead.

--tablespace-slim-data=TABLESPC

Store the slim mode tables in the given tablespace.

--tablespace-slim-index=TABLESPC

Store the indexes of the slim mode tables in the given tablespace.

-p,  --prefix=PREFIX

Prefix for table names (default: planet_osm).

-s,  --slim

Store temporary data in the database. Without this mode, all temporary data is stored in RAM and if you do not have enough the import will not work successfully. With slim mode, you should be able to import the data even on a system with limited RAM, although if you do not have enough RAM to cache at least all of the nodes, the time to import the data will likely be greatly increased.

--drop

Drop the slim mode tables from the database and the flat node file once the import is complete. This can greatly reduce the size of the database, as the slim mode tables typically are the same size, if not slightly bigger than the main tables. It does not, however, reduce the maximum spike of disk usage during import. It can furthermore increase the import speed, as no indexes need to be created for the slim mode tables, which (depending on hardware) can nearly halve import time. Slim mode tables however have to be persistent if you want to be able to update your database, as these tables are needed for diff processing.

-C,  --cache=NUM

Only for slim mode: Use up to NUM MB of RAM for caching nodes. Giving osm2pgsql sufficient cache to store all imported nodes typically greatly increases the speed of the import. Each cached node requires 8 bytes of cache, plus about 10% - 30% overhead. As a rule of thumb, give a bit more than the size of the import file in PBF format. If the RAM is not big enough, use about 75% of memory. Make sure to leave enough RAM for PostgreSQL. It needs at least the amount of shared_buffers given in its configuration. Defaults to 800.

-x,  --extra-attributes

Include attributes of each object in the middle tables and make them available to the outputs. Attributes are: user name, user id, changeset id, timestamp and version.

-F,  --flat-nodes=FILENAME

Use a file on disk to store node locations instead of storing them in memory (in non-slim mode) or in the database (in slim mode). This is much more efficient than storing the data in the database. Storing the node information for the full planet requires more than 500GB in PostgreSQL, the same data is stored in “only” 90GB using the flat-nodes mode. This can also increase the speed of applying diff files. This option activates the flat-nodes mode and specifies the location of the database file. It is a single large file. This mode is only recommended for full planet imports as it doesn’t work well with small imports. The default is disabled. The file will stay on disk after import, use --drop to remove it (but you can’t do updates then).

--middle-schema=SCHEMA

Use PostgreSQL schema SCHEMA for all tables, indexes, and functions in the middle. The schema must exist in the database and be writable by the database user. By default the schema set with --schema is used, or public if that is not set.

--middle-with-nodes

When a flat nodes file is used, nodes are not stored in the database. Use this option to force storing nodes with tags in the database, too.

-O,  --output=OUTPUT

Specifies the output to use. Currently osm2pgsql supports pgsql, flex, and null. pgsql is the default output still available for backwards compatibility. New setups should use the flex output which allows for a much more flexible configuration. The null output does not write anything and is only useful for testing or with --slim for creating slim tables.

-S,  --style=FILE

The style file. This specifies how the data is imported into the database, its format depends on the output. (For the pgsql output, the default is /usr/share/osm2pgsql/default.style, for other outputs there is no default.)

--tablespace-main-data=TABLESPC

Store the data tables in the PostgreSQL tablespace TABLESPC.

--tablespace-main-index=TABLESPC

Store the indexes in the PostgreSQL tablespace TABLESPC.

--latlong

Store coordinates in degrees of latitude & longitude.

-m, --merc

Store coordinates in Spherical Mercator (Web Mercator, EPSG:3857) (the default).

-E, --proj=SRID

Use projection EPSG:SRID.

-p, --prefix=PREFIX

Prefix for table names (default: planet_osm). This option affects the middle as well as the pgsql output table names.

--tag-transform-script=SCRIPT

Specify a Lua script to handle tag filtering and normalisation. The script contains callback functions for nodes, ways and relations, which each take a set of tags and returns a transformed, filtered set of tags which are then written to the database.

-x, --extra-attributes

Include attributes (user name, user id, changeset id, timestamp and version). This also requires additional entries in your style file.

-k, --hstore

Add tags without column to an additional hstore (key/value) column in the database tables.

-j, --hstore-all

Add all tags to an additional hstore (key/value) column in the database tables.

-z, --hstore-column=PREFIX

Add an additional hstore (key/value) column named PREFIX containing all tags that have a key starting with PREFIX, eg \--hstore-column "name:" will produce an extra hstore column that contains all name:xx tags.

--hstore-match-only

Only keep objects that have a value in at least one of the non-hstore columns.

--hstore-add-index

Create indexes for all hstore columns after import.

-G, --multi-geometry

Normally osm2pgsql splits multi-part geometries into separate database rows per part. A single OSM object can therefore use several rows in the output tables. With this option, osm2pgsql instead generates multi-geometry features in the PostgreSQL tables.

-K, --keep-coastlines

Keep coastline data rather than filtering it out. By default objects tagged natural=coastline will be discarded based on the assumption that Shapefiles generated by OSMCoastline (https://osmdata.openstreetmap.de/) will be used for the coastline data.

--reproject-area

Compute area column using spherical mercator coordinates even if a different projection is used for the geometries.

--output-pgsql-schema=SCHEMA

Use PostgreSQL schema SCHEMA for all tables, indexes, and functions in the pgsql output. The schema must exist in the database and be writable by the database user. By default the schema set with --schema is used, or public if that is not set.

-e,  --expire-tiles=[MIN_ZOOM-]MAX-ZOOM

Create a tile expiry list.

-o,  --expire-output=FILENAME

Output file name for expired tiles list.

--expire-bbox-size=SIZE

Max size for a polygon to expire the whole polygon, not just the boundary.

-I,  --disable-parallel-indexing

Disable parallel clustering and index building on all tables, build one index after the other.

--number-processes=THREADS

Specifies the number of parallel threads used for certain operations.
