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

       -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 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=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 time-filter 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 time-filter does all its work on the fly and doesn’t keep much data in main memory.

EXAMPLES

       Extract current planet file from history planet:

              osmium time-filter -o planet.osm.pbf history-planet.osh.pbf

       Extract planet data how it appeared on January 1 2008 from history planet:

              osmium time-filter -o planet-20080101.osm.pbf history-planet.osh.pbf 2008-01-01T00:00:00Z
