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
option to show more information.
Normally this command will output the data in human readable form. If the
-j,
--json option is used, the output will be in JSON format
instead.
If the
-g,
--get option is used, only the value of the named
variable will be printed.
The output is split into three 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 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).
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.
- -G, --show-variables
- Show a list of all variable names.
- -j, --json
- Output in JSON format. Can not be used together with --get.
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 STDERR is
detected to be a 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 STDERR is
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.
- -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.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 wih 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.maxid.nodes - INTEGER
data.maxid.ways - INTEGER
data.maxid.relations - INTEGER
data.maxid.changesets - INTEGER
All timestamps are in the usual OSM ISO format yy-mm-ddThh::mm::ssZ. Boxes are
in the format (xmin, ymin, xmax, ymax).
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.
