Ubuntu Manpage: osmium-fileinfo - show information about an OSM file

Provided by: osmium-tool_1.11.1-1build2_amd64

NAME

       osmium-fileinfo - show information about an OSM file

SYNOPSIS

       osmium fileinfo [OPTIONS] OSM-FILE

DESCRIPTION

Shows various information about OSM files such as the file type, bounding boxes in the header, etc.

This command will usually only read the file header. Use the --extended/-e option to show more
information.

Normally this command will output the data in human readable form. If the --json/-j option is used, the
output will be in JSON format instead.

If the --get/-g option is used, only the value of the named variable will be printed.

The output is split into four sections:

File This section shows the information available without opening the file itself. It contains the
file name, the format deduced from the file name, the compression used and the size of the file in
bytes.

Header This section shows the information available from the header of the file (if available, OPL files
have no header). Any available bounding boxes are shown as well as header options such as the
generator and file format version.

Data This section shows the information available from reading the whole file. It is only shown if the
--extended/-e option was used. It shows the actual bounding box calculated from the nodes in the
file, the first and last timestamp of all objects in the file, a CRC32 checksum of the data in the
file, the number of changesets, nodes, ways, and relations found in the file, whether the objects
in the file were ordered by type (nodes, then ways, then relations) and id, and whether there were
multiple versions of the same object in the file (history files and change files can have that).
See the osmium-sort(1) man page for details of the expected ordering.

Metadata
This section shows which metadata attributes are used in the file. It contains information which
attributes are used by all objects in the file and which are only used by some objects. This
section is only shown if the --extended/-e option was used because the whole file has to be read.

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

OPTIONS

       -e, --extended
              Read the complete file and show additional information.  The default is to read only the header of
              the file.

       -g, --get=VARIABLE
              Get value of VARIABLE.  Can not be used together with --json/-j.

       -G, --show-variables
              Show a list of all variable names.

       -j, --json
              Output in JSON format.  Can not be used together with --get/-g.

       -t, --object-type=TYPE
              Read only objects of given type (node, way, relation, changeset).  By default all types are  read.
              This  option  can  be given multiple times.  This only takes effect if the --extended/-e option is
              also used.

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.

       All timestamps are in the usual OSM ISO format yy-mm-ddThh::mm::ssZ.  Boxes  are  in  the  format  (xmin,
       ymin, xmax, ymax).

       There  are  two  variables for each metadata field.  The metadata.all_objects.* variables are true if all
       objects in the file have the attribute.  The metadata.some_objects.* variables are true if at  least  one
       object  in  the file has the attribute.  Please note that objects last modified by anonymous users (until
       2007) do not have user and uid attributes and can lead to wrong results.

DIAGNOSTICS

       osmium fileinfo 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 fileinfo does all its work on the fly and doesn’t keep much data in main memory.
