NAME

osmium-apply-changes - apply OSM change file(s) to OSM data file

SYNOPSIS

osmium apply-changes [OPTIONS] OSM-DATA-FILE OSM-CHANGE-FILE…
osmium apply-changes [OPTIONS] OSM-HISTORY-FILE OSM-CHANGE-FILE…

DESCRIPTION

Merges the content of all OSM change files and applies those changes to the OSM data or history file.

Objects in the data or history file must be sorted by type, ID, and version.

Objects in change files need not be sorted, so it doesn’t matter in what order the change files are given or in what order they contain the data. (If you are using change files of extracts this is not necessarily true and you must specify the change files on the command line in the correct order from oldest to newest. This is because change files from extracts can contain multiple different object versions with the same version and timestamp!)

Changes can be applied to normal OSM data files or OSM history files with this command. File formats will be autodetected from the file name suffixes, see the --with-history/-H option if that doesn’t work.

This commands reads its input file(s) only once and writes its output file in one go so it can be streamed, ie. it can read from STDIN and write to STDOUT.

OPTIONS

-H, --with-history
Update an OSM history file (instead of a normal OSM data file). Both input and output must be history files. This option is usually not necessary, because history files will be detected from their file name suffixes, but if this detection doesn’t work, you can force this mode with this option. Can not be used together with the --locations-on-ways option.
--locations-on-ways
Input has and output should have node locations on ways. Can be used to update files created by the osmium-add-locations-to-ways. See there for details on the format. Can not be used together with the --with-history/-H option.
--redact
Redact (patch) history files. Change files can contain any version of any object which will replace that version of that object from the input. This allows changing the history! This mode is for special use only, for instance to remove copyrighted or private data.

COMMON OPTIONS

-h, --help
Show usage help.
-v, --verbose
Set verbose mode. The program will output information about what it is doing to STDERR.
--progress
Show progress bar. Usually a progress bar is only displayed if STDOUT and STDERR are detected to be TTY. With this option a progress bar is always shown. Note that a progress bar will never be shown when reading from STDIN or a pipe.
--no-progress
Do not show progress bar. Usually a progress bar is displayed if STDOUT and STDERR are detected to be a TTY. With this option the progress bar is suppressed. Note that a progress bar will never be shown when reading from STDIN or a pipe.

INPUT OPTIONS

-F, --input-format=FORMAT
The format of the OSM-DATA-FILE or OSM-HISTORY-FILE. Can be used to set the input format if it can’t be autodetected from the file name. See osmium-file-formats(5) or the libosmium manual for details.
--change-file-format=FORMAT
The format of the OSM-CHANGE-FILE(s). Can be used to set the input format if it can’t be autodetected from the file name(s). This will set the format for all change files, there is no way to set the format for some change files only. See osmium-file-formats(5) or the libosmium manual for details.

OUTPUT OPTIONS

-f, --output-format=FORMAT
The format of the output file. Can be used to set the output file format if it can’t be autodetected from the output file name. See osmium-file-formats(5) or the libosmium manual for details.
--fsync
Call fsync after writing the output file to force flushing buffers to disk.
--generator=NAME
The name and version of the program generating the output file. It will be added to the header of the output file. Default is “osmium/” and the version of osmium.
-o, --output=FILE
Name of the output file. Default is ‘-’ (STDOUT).
-O, --overwrite
Allow an existing output file to be overwritten. Normally osmium will refuse to write over an existing file.
--output-header=OPTION=VALUE
Add output header option. This command line option can be used multiple times for different OPTIONs. See the osmium-output-headers(5) man page for a list of available header options. For some commands you can use the special format “OPTION!” (ie. an exclamation mark after the OPTION and no value set) to set the value to the same as in the input file.

DIAGNOSTICS

osmium apply-changes exits with exit code

0
if everything went alright,
1
if there was an error processing the data, or
2
if there was a problem with the command line arguments.

MEMORY USAGE

osmium apply-changes keeps the contents of all the change files in main memory. This will take roughly 10 times as much memory as the files take on disk in .osm.bz2 format.

EXAMPLES

Apply changes in 362.osc.gz to planet file and write result to new.osm.pbf:

osmium apply-changes --output=new.osm.pbf planet.osm.pbf 362.osc.gz
