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
-c, --crc
Calculate the CRC32. This is the default if you use the JSON output format.
--no-crc
Do not calculate the CRC32. This is the default unless you use the JSON output
format.
-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.
VARIABLES
The following variables are available:
file.name - STRING
file.format - STRING: XML|PBF
file.compression - STRING: none|bzip2|gzip
file.size - INTEGER (always 0 when reading from STDIN)
header.boxes - STRING (could be multiline)
header.with_history - BOOL (yes|no)
header.option.generator - STRING
header.option.version - STRING
header.option.pbf_dense_nodes - BOOL (yes|no)
header.option.osmosis_replication_timestamp - STRING with TIMESTAMP
header.option.osmosis_replication_sequence_number - INTEGER
header.option.osmosis_replication_base_url - STRING
data.bbox - BOX
(in JSON as nested ARRAY with coordinates)
data.timestamp.first - STRING with TIMESTAMP
data.timestamp.last - STRING with TIMESTAMP
data.objects_ordered - BOOL (yes|no)
data.multiple_versions - STRING (yes|no|unknown)
(in JSON as BOOL and missing if "unknown")
data.crc32 - STRING with 8 hex digits
data.count.nodes - INTEGER
data.count.ways - INTEGER
data.count.relations - INTEGER
data.count.changesets - INTEGER
data.minid.nodes - INTEGER
data.minid.ways - INTEGER
data.minid.relations - INTEGER
data.minid.changesets - INTEGER
data.maxid.nodes - INTEGER
data.maxid.ways - INTEGER
data.maxid.relations - INTEGER
data.maxid.changesets - INTEGER
data.buffers.count - INTEGER
data.buffers.size - INTEGER
data.buffers.capcity - INTEGER
metadata.all_objects.version - BOOL (yes|no)
metadata.all_objects.timestamp - BOOL (yes|no)
metadata.all_objects.changeset - BOOL (yes|no)
metadata.all_objects.uid - BOOL (yes|no)
metadata.all_objects.user - BOOL (yes|no)
metadata.some_objects.version - BOOL (yes|no)
metadata.some_objects.timestamp - BOOL (yes|no)
metadata.some_objects.changeset - BOOL (yes|no)
metadata.some_objects.uid - BOOL (yes|no)
metadata.some_objects.user - BOOL (yes|no)
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.
