NAME

       osmium-check-refs - check referential integrity of OSM file

SYNOPSIS

       osmium check-refs [OPTIONS] OSM-DATA-FILE

DESCRIPTION

       Ways  in OSM files refer to OSM nodes; relations refer to nodes, ways, or other relations.
       This command checks whether all objects referenced in the input file are also  present  in
       the input file.

       Referential  integrity  is  often broken in extracts.  This can lead to problems with some
       uses of the OSM data.  Use this command to make sure your data is good.

       If the option --check-relations/-r is not given, this command will only check if all nodes
       referenced in ways are in the file, with the option, relations will also be checked.

       This  command  expects the input file to be ordered in the usual way: First nodes in order
       of ID, then ways in order of ID, then relations in order of ID.  Negative IDs are allowed,
       they must be ordered before the positive IDs.  See the osmium-sort(1) man page for details
       of the ordering.

       This command will only work for OSM data files, not OSM history files or change files.

       This commands reads its input file only once, ie.  it can read from STDIN.

OPTIONS

       -i, --show-ids
              Print all missing IDs to STDOUT.  If you don’t specify this option, only a  summary
              is shown.

       -r, --check-relations
              Also  check referential integrity of relations.  Without this option, only nodes in
              ways are checked.

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.

MEMORY USAGE

       osmium check-refs will do the check in one pass through the input data.  It  needs  enough
       main memory to store all temporary data.

       Largest memory need will be about 1 bit for each node ID, that’s roughly 860 MB these days
       (February 2020).  With the --check-relations/-r option memory use will be a bit bigger.

DIAGNOSTICS

       osmium check-refs exits with exit code

       0      if all references are satisfied

       1      if there was an error processing the data or some references were not satisfied, or

       2      if there was a problem with the command line arguments.
