osmium-time-filter — filter OSM data by time from a history file


osmium time-filter [OPTIONS] OSM-HISTORY-FILE [TIME]



Copy all objects that were valid at the given TIME or in the time period between FROM-TIME (inclusive) and TO-TIME (not inclusive) from the input file into the output file. If no time is given, the current time is used.

Usually the INPUT-FILE will be an OSM data file with history. If both FROM-TIME and TO-TIME are given, the result will also have history data, it will also include deleted versions of objects.

If only a single point in time was given, the result will be a normal OSM file without history containing no deleted objects.

The format for the timestamps is "yyyy-mm-ddThh:mm::ssZ".

This commands reads its input file 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.

Common Options

-h, --help

Show usage help.

-v, --verbose

Set verbose mode. The program will output information about what it is doing to STDERR.

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.


Call fsync after writing the output file to force flushing buffers to disk.


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.


Add output header option. This option can be given several times. See the libosmium manual for a list of allowed header options.
