Osmosis/Detailed Usage 0.37

This page describes the complete set of command line options available for the Osmosis tool.

Global Options

Short Option	Long Option	Description
-v	-verbose	Specifies that increased logging should be enabled.
-v x	-verbose x	x is a positive integer specifying the amount of increased logging, 0 is equivalent to the -v option alone.
-q	-quiet	Specifies that reduced logging should be enabled.
-q x	-quiet x	x is a positive integer specifying the amount of increased logging, 0 is equivalent to the -q option alone.
-p <plugin_class>	-plugin <plugin_class>	Allows an external plugin to be loaded. <plugin_class> is the name of a class implementing the com.bretth.osmosis.core.plugin.PluginLoader interface. This option may be specified multiple times to load multiple plugins.

Default Arguments

Some tasks can accept un-named or "default" arguments. In the tasks description, the argument name will be followed by "(default)".

For example, the --read-xml task has a file argument which may be unnamed. The following two command lines are equivalent.

osmosis --read-xml file=myfile.osm --write-null

osmosis --read-xml myfile.osm --write-null

Built-In Tasks

All tasks default to 0.6 versions from release 0.31 onwards.

0.6 tasks were first introduced in release 0.30. 0.5 tasks were dropped as of vresion 0.36. 0.4 tasks were dropped as of version 0.22.

API Database Tasks

The tasks are to be used with the schema that backs the OSM API. These tasks support the 0.6 database only, and support both PostgreSQL and MySQL variants. It is highly recommended to use PostgreSQL due to the better testing it receives.

Pipe	Description
inPipe.0	Consumes an entity stream.

Option	Description	Valid Values	Default Value
file (default)	The name of the osm file to be written, "-" means STDOUT.		dump.osm

BitSet is more efficient for very large bounding boxes (where node count is greater than 1/32 of maximum node id), IdList will be more efficient for all smaller bounding boxes. Dynamic breaks the overall id range into small segments and chooses the most efficient of IdList or BitSet for that interval.	BitSet, IdList, Dynamic	Dynamic
clipIncompleteEntities	0.6 only. Specifies what the behaviour should be when entities are encountered that have missing relationships with other entities. For example, ways with missing nodes, and relations with missing members. This occurs most often at the boundaries of selection areas, but may also occur due to referential integrity issues in the database or inconsistencies in the planet file snapshot creation. If set to true the entities are modified to remove the missing references, otherwise they're left intact.	true, false	false

If both lat/lon and slippy map coordinates are used then lat/lon coordinates are overriden by slippy map coordinates.

The clipIncompleteEntities was introduced in version 0.30 and changes default behaviour. It now defaults to false, but the previous behaviour was clipIncompleteEntities=true.

--bounding-polygon (--bp)

Extracts data within a polygon defined by series of lat/lon coordinates loaded from a polygon file.

The format of the polygon file is described at the MapRoom website, with two exceptions:

• A special extension has been added to this task to support negative polygons, these are defined by the addition of a "!" character preceding the name of a polygon header within the file. See an example on the Polygon filter file format page to get a better understanding of how to use negative polygons.
• The first coordinate pair in the polygon definition is not, as defined on the MapRoom site, the polygon centroid; it is the first polygon point. The centroid coordinates are not required by Osmosis (nor are they expected but they won't break things if present and counted as part of the polygon outline).
• An explicit example is provided on the Polygon filter file format page.
• You can find some polygons for european countries at the OSM-Subversion

Data Manipulation Tasks

These tasks allow the entities being passed through the pipeline to be manipulated.

--node-key (--nk)

Given a list of "key" tags, this filter passes on only those nodes that have at least one of those tags set.

Note that this filter only operates on nodes. All ways and relations are filtered out.

This filter will only be available with version >= 0.30 (or svn).

Pipe	Description
inPipe.0	Consumes an entity stream.
outPipe.0	Produces an entity stream.

Option	Description	Valid Values	Default Value
keyList	Comma-separated list of desired keys		N/A

--node-key-value (--nkv)

Given a list of "key.value" tags, this filter passes on only those nodes that have at least one of those tags set.

Note that this filter only operates on nodes. All ways and relations are filtered out.

This filter will only be available with version >= 0.30 (or svn).

Option	Description	Valid Values	Default Value
keyValueList	Comma-separated list of desired key.value combinations		N/A

--way-key (--wk)

Given a list of "key" tags, this filter passes on only those ways that have at least one of those tags set.

Note that this filter only operates on ways. All nodes and relations are passed on unmodified.

This filter is currently only available in svn.

Note that this filter only operates on ways. All nodes and relations are passed on unmodified.

Pipe	Description

outPipe.0	Produces an entity stream.

Option	Description	Valid Values	Default Value
keyValueList	Comma-separated list of desired key.value combinations		highway.motorway,highway.motorway_link,highway.trunk,highway.trunk_link

--tag-filter (--tf)

Filters entities based on their type and optionally based on their tags. Can accept or reject entities that match the filter specification.

Pipe	Description
inPipe.0	Consumes an entity stream.
outPipe.0	Produces an entity stream.

Option	Description	Valid Values	Default Value
filter mode (default)	A two-field dash-separated string which specifies accept/reject behavior and the entity type on which this filter operates.	accept-nodes, accept-ways, accept-relations, reject-nodes, reject-ways, reject-relations	empty string

All keyword arguments are interpreted as tag parameters. They should be in the form "key=value" and specify which tags are matched by this filter. Each tag-filter task operates only on the specified entity type (passing other entity types through without touching them), and within that type accepts or rejects entities according to its tag parameters. If no tag parameters are specified, the filter matches all tags. Multiple values can be specified for one key, in a comma-separated list. A tag value list of * (a single asterisk) matches any value.

The separator character, equality character, and wildcard character ( , = * respectively) can be included in keys or values using the following escape sequences:

Escape sequence	Replaced with
%a	*
%c	,
%e	=
%s	space
%%	literal '%' symbol

In practice, there are only limited circumstances where you absolutely must escape these characters:

• = must be escaped in tag keys
• , must be escaped in tag values
• * only needs to be escaped for tag values that consist of a single *
• % and space must always be escaped.

Example usage:

osmosis \
  --read-xml input.osm \
  --tf accept-ways highway=* \ 
  --tf reject-ways highway=motorway,motorway_link \
  --tf reject-relations \
  --used-node \
  --write-xml output.osm

This will keep only ways with tag highway=(anything), then throw away those ways where tag highway is motorway or motorway_link. All relations are discarded, then all nodes which are not in the ways are discarded. The remaining entities are written out in XML.

You may need to work on two separate entity streams and merge them after filtering. If both inputs for the merge are coming from the same thread (e.g. using the tee task followed by the merge task), Osmosis will experience deadlock and the operation will never finish. One solution is to read the data in two separate tasks:

../osmosis/bin/osmosis \ 
  --rx input.osm \
  --tf reject-relations \
  --tf accept-nodes amenity=* \
  --tf reject-ways outPipe.0=POI \
  \
  --rx input.osm \
  --tf reject-relations \
  --tf accept-ways highway=motorway \
  --used-node outPipe.0=motorway \ 
  \
  --merge inPipe.0=POI inPipe.1=motorway \
  --wx test-merge.osm

--used-node (--un)

Restricts output of nodes to those that are used in ways.

Pipe	Description
inPipe.0	Consumes an entity stream.
outPipe.0	Produces an entity stream.

Option	Description	Valid Values	Default Value
idTrackerType	Specifies the memory mechanism for tracking selected ids. BitSet is more efficient for very large bounding boxes (where node count is greater than 1/32 of maximum node id), IdList will be more efficient for all smaller bounding boxes.	BitSet, IdList	IdList

PostGIS Tasks

Osmosis provides a PostGIS schema for storing a snapshot of OSM data. All geo-spatial aspects of the data are stored using PostGIS geometry data types. Node locations are always stored as a point. Ways are related to nodes as in the normal API schema, however they may optionally have bounding box and/or full linestring columns added as well allowing a full set of geo-spatial operations to be performed on them.

To perform queries on this schema, see #Dataset Tasks.

The schema creation scripts can be found in the scripts directory within the osmosis distribution. These scripts are:

• pgsql_simple_schema_0.6.sql - Builds the minimal schema.
• pgsql_simple_schema_0.6_action.sql - Adds the optional "action" table which allows derivative tables to be kept up to date when diffs are applied.
• pgsql_simple_schema_0.6_bbox.sql - Adds the optional bbox column to the way table.
• pgsql_simple_schema_0.6_linestring.sql - Adds the optional linestring column to the way table.
• pgsql_simple_load_0.6.sql - A sample data load script suitable for loading the COPY files created by the --write-pgsql-dump task.

Osmosis_PostGIS_Setup describes a procedure for setting up Postgresql/PostGIS for use with osmosis.

--write-pgsql (--wp)

Populates an empty PostGIS database with a "simple" schema. A schema creation script is available in the osmosis script directory.

The 0.5 schema is a one size fits all solution. The 0.6 schema has a number of optional columns and tables that can be optionally installed with additional schema creation scripts. This task queries the schema to automatically detect which of those features is installed.

Dataset Tasks

Dataset tasks are those that act on on the generic dataset interface exposed by several data stores. For example the #PostGIS Tasks. These tasks allow data queries and data manipulation to be performed in a storage method agnostic manner.

--dataset-bounding-box (--dbb)

Extracts data within a specific bounding box defined by lat/lon coordinates. This differs from the --bounding-box task in that it operates on a dataset instead of an entity stream, in other words it uses the features of the underlying database to perform a spatial query instead of examining all nodes in a complete stream.

This implementation will never clip ways at box boundaries, and depending on the underlying implementation may detect ways crossing a box without having any nodes within that box.

inPipe.0	Consumes a dataset.
outPipe.0	Produces an entity stream.

Option	Description	Valid Values	Default Value

Replication Tasks

These tasks are used for replicating changes between data stores. They typically work with change streams and can therefore be coupled with other change stream tasks depending on the job to be performed.

There are two major types of change files:

• Delta - Contain minimal changes to update a dataset. This implies a maximum of 1 change per entity.
• Full-History - Contain the full set of historical changes. This implies that there may be multiple changes per entity.

All tasks support the "delta" style of changesets. Some tasks do not support the "full-history" change files.

--read-change-interval (--rci)

Retrieves a set of change files from a server, merges them into a single stream, and tracks the current timestamp.

The changes produced by this task are typically delta changes.

Pipe	Description
outPipe.0	Produces a change stream.

Option	Description	Valid Values	Default Value
workingDirectory (default)	The directory containing the state and config files.		(current directory)

--read-change-interval-init (--rcii)

--read-replication-interval (--rri)

Retrieves a set of replication files from a server, combines them into a single stream, sorts the result, and tracks the current timestamp. Available since osmosis 0.32.

The changes produced by this task are typically full-history changes.

Pipe	Description
outPipe.0	Produces a change stream.

Option	Description	Valid Values	Default Value
workingDirectory (default)	The directory containing the state and config files.		(current directory)

--read-replication-interval-init (--rrii)

Pipe	Description
n/a

Option	Description	Valid Values	Default Value
workingDirectory (default)	The directory to populate with state and config files.		(current directory)

Note: This will create a configuration.txt and a download.lock file in the <workingDirectory>. Then you need to manually edit the configuration.txt file and change the url to the one of minute or hourly replicate (eg : baseUrl=https://planet.openstreetmap.org/minute-replicate for the web or baseUrl=file:///your/replicate-folder for local filesystem)

If no state.txt file exists, the first invocation will result in the latest state file being downloaded. If you wish to start from a known point you need to download from https://planet.openstreetmap.org/minute-replicate the state file of the start date you want for your replication put it into your <workingDirectory> with name state.txt. You can use the replicate-sequences tool to find a matching file. Take one at least an hour earlier than your start date to avoid missing changes.

If you wish to start from a known point you need to download from https://planet.openstreetmap.org/minute-replicate the state file of the start date you want for your replication put it into your <workingDirectory> with name state.txt. You can use the replicate-sequences tool to find a matching file. Take one at least an hour earlier than your start date to avoid missing changes.

--replicate-apidb (--repa)

This task provides replication files for consumers to download. It is primarily run against the production API database with the results made available on the planet server.

The first time this task runs it will initialise the working directory with the current state of the database server. Every subsequent invocation will read all changes since the last invocation and write the results to the output. All changes will be sorted by type, then id, then version.

directory	The working directory.		replicate

--read-replication-lag (--rrl)

This Task takes the state.txt in an replication working directory and compares its timestamp (that's the timestamp of the last chunk of that that osmosis downloaded) with the timestamp of the servers state.txt (that's the timestamp of the last chunk of that that the server has produced). It then calculates the difference and prints it to stdout. In order to get only the printed value its often useful to pipe the log messages on stderr to /dev/null.

a sample invocation may look like

osmosis --read-replication-lag humanReadable=yes workingDirectory=/osm/diffs 2>/dev/null

Pipe	Description
n/a

Option	Description	Valid Values	Default Value

Option	Description	Valid Values	Default Value
file (default)	The name of the file to be read.		dump.osm.pbf

--write-pbf (--wb)

Writes data to an OSM binary file.

inPipe.0	Consumes an entity stream.

Option	Description	Valid Values	Default Value
file (default)	The name of the file to be written.		dump.osm.pbf
batchlimit	Block size used when compressing. This is a reasonable default. Batchlimits that are too big may cause files to exceed the defined filesize limits.	Integer value.	8000
omitmetadata	Omit non-geographic metadata on OSM entities. This includes version number and timestamp of the last edit to the entity as well as the user name and id of the last modifier. Omitting this metadata can save 15% of the file size when exporting to software that does not need this data.	true, false	false
usedense	Nodes can be represented in a regular format or a dense format. The dense format is about 30% smaller, but more complex. To make it easier to interoperate with (future) software that chooses to not implement the dense format, the dense format may be disabled.	true, false	true
granularity	The granularity or precision used to store coordinates. The default of 100 nanodegrees is the highest precision used by OSM, corresponding to about 1.1cm at the equator. In the current osmosis implementation, the granularity must be a multiple of 100. If map data is going to be exported to software that does not need the full precision, increasing the granularity to 10000 nanodegrees can save about 10% of the file size, while still having 1.1m precision.	Integer value.	100
compress	'deflate' uses deflate compression on each block. 'none' disables compression. These files are about twice as fast to write and twice the size.	deflate, none	deflate

--simplify

The simplify plugin filters to drop some elements in order to simplify the data. Currently it does one extremely crude form of simplification. It drops all nodes apart from the start and end nodes of every way.

Database Login Credentials

All database tasks accept a minimum of four arguments, these are:

• authFile
• host
• database
• user
• password
• dbType

If no arguments are passed, then the default values for host, database, user and password apply.

If authFile is supplied, it must point to a properties file with name value pairs specifying host, database, user and password. For example:

host=localhost
database=osm
user=osm
password=mypassword
dbType=postgresql

Note that the properties file doesn't have to contain all parameters, it may contain only the password leaving other parameters to be specified on the command line separately.

Command line arguments override the authFile parameters, which in turn override the default argument values.

Munin Plugin

Together with the --read-replication-lag-Task Osmosis 0.36 contains a munin plugin that graphs the replication lag, that's the time difference between the local state-file and the state of the server.

To enable it, locate the munin files in your distribution. They are located in a subdir named "script/munin/" and follow the following instructions:

1. copy "osm-replication-lag" to "/usr/share/munin/plugins"
2. make "/usr/share/munin/plugins/osm-replication-lag" executable
3. symlink "/usr/share/munin/plugins/osm-replication-lag" to "/etc/munin/plugins"
4. copy "osm-replication.conf" to "/etc/munin/plugin-conf.d"
5. edit "/etc/munin/plugin-conf.d/osm-replication.conf" and set the workingDirectory
6. restart the munin-node
