OSMIUM-FILEINFO(1) OSMIUM-FILEINFO(1) 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 bound- ing 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 os- mium-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 STD- OUT 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 for- mat 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 for- mat 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_ob- jects.* 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.
