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


SYNOPSIS
       osmium check-refs [OPTIONS] INPUT-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.

       This  command 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 1 bit for each node ID, thats roughly 500 MB these  days
       (Summer 2015).

       If  the  option  -r is not given, this command will only check if all nodes references 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.


OPTIONS
       -F, --input-format=FORMAT
              The  format  of  the  input file.  Can be used to set the input format if it can't be autodetected
              from the file name.  See osmium-file-formats(5) or the libosmium manual for details.

       -i, --show-ids
              Print all missing IDs to stdout.  If you don't give 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.

       -v, --verbose
              Set verbose mode.  The program will output information about what it is doing to stderr.


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.
