OSMIUM-TIME-FILTER(1) OSMIUM-TIME-FILTER(1)

NAME

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

SYNOPSIS

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

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

DESCRIPTION

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

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

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

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.
Name of the output file. Default is `-' (STDOUT).
Allow an existing output file to be overwritten. Normally osmium will refuse to write over an existing file.
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.
