osmium-getid — get objects from OSM file by ID

Synopsis

osmium getid [Options] OSM-FILE ID...

osmium getid [Options] OSM-FILE -i ID-FILE

osmium getid [Options] OSM-FILE -I ID-OSM-FILE

Description

Get objects with the given IDs from the input and write them to the output.

IDs can be given on the command line (first case in synopsis), or read from text files with one ID per line (second case in synopsis), or read from OSM files (third cases in synopsis). A mixture of these cases is also allowed.

All objects with these IDs will be read from OSM-FILE and written to the output. If the option -r, --add-referenced is used all objects referenced from those objects will also be added to the output.

Objects will be written out in the order they are found in the OSM-FILE.

If the option -r, --add-referenced is not used, the input file is read only once, if it is used, the input file will possibly be read up to three times.

On the command line or in the ID file, the IDs have the form: TYPE-LETTER NUMBER. The type letter is 'n' for nodes, 'w' for ways, and 'r' for relations. If there is no type letter, 'n' for nodes is assumed (or whatever the --default-type option says). So "n13 w22 17 r21" will match the nodes 13 and 17, the way 22 and the relation 21.

The order in which the IDs appear does not matter. Identical IDs can appear multiple times on the command file or in the ID file(s).

On the command line, the list of IDs can be in separate arguments or in a single argument separated by spaces, tabs, commas (,), semicolons (;), forward slashes (/) or pipe characters (|).

In an ID file (option -i/--id-file) each line must start with an ID in the format described above. Lines can optionally contain a space character or a hash sign ('#') after the ID. Any characters after that are ignored. (This also allows files in OPL format to be read.) Empty lines are ignored.

Note that all objects will be taken from the OSM-FILE, the ID-OSM-FILE is only used to detect which objects to get. This might matter if there are different object versions in the different files.

The OSM-FILE can not be a history file unless the -H, --history option is used. Then all versions of the objects will be copied to the output.

If referenced objects are missing from the input file, the type and IDs of those objects is written out to stderr at the end of the program unless the -H, --history option was given.

This command will not work with negative IDs.

Options

--default-type=TYPE
Use TYPE ('node', 'way', or 'relation') for IDs without a type prefix (default: 'node'). It is also allowed to just use the first character of the type here.
-H, --history
Make this program work on history files. This is only needed when using the -r option.
-i, --id-file[=FILE]
Read IDs from text file instead of from the command line. Use the special name "-" to read from stdin. Each line of the file must start with an ID in the format described above. Lines can optionally contain a space character or a hash sign ('#') after the ID. This character and all following characters are ignored. (This allows files in OPL format to be read.) Empty lines are also ignored. This option can be used multiple times.
-I, --id-osm-file=OSMFILE
Like -i but get the IDs from an OSM file. This option can be used multiple times.
-r, --add-referenced
Recursively find all objects referenced by the objects of the given IDs and include them in the output. This only works correctly on non-history files unless the -H option is also used.
--verbose-ids
Also print all requested and missing IDs. This is usually disabled, because the lists can get quite long. (This option implies --verbose.)

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 STDERR is detected to be a 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 STDERR is 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 input 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 input files, there is no way to set the format for some input 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
Add output header option. This option can be given several times. See the libosmium manual for a list of allowed header options.

Diagnostics

osmium getid exits with exit code

0
if all IDs were found
1
if there was an error processing the data or not all IDs were found, (this is only detected if the -h, --history option was not used),
2
if there was a problem with the command line arguments.

Memory Usage

osmium getid does all its work on the fly and only keeps a table of all IDs it needs in main memory.

Examples

Output nodes 17 and 1234, way 42, and relation 111 to stdout in OPL format:

osmium getid -f opl planet.osm.pbf n1234 w42 n17 r111
