6 osmium-cat - concatenate OSM files and convert to different formats
7
9 osmium cat [OPTIONS] OSM-FILE...
10
12 Concatenates all input files and writes the result to the output file.
13 The data is not sorted in any way but strictly copied from input to
14 output.
15 Because this program supports several different input and output for‐
17 mats, it can be used to convert OSM files from one format into another.
18 This commands reads its input file(s) only once and writes its output
20 file in one go so it can be streamed, ie. it can read from STDIN and
21 write to STDOUT.
22
24 -c, --clean=ATTR
25 Clean the attribute (version, timestamp, changeset, uid, user),
26 from the data before writing it out again. The attribute will
27 be set to 0 (the user will be set to the empty string). This
28 option can be given multiple times. Depending on the output
29 format these attributes might show up as 0 or not show up at
30 all.
31 -t, --object-type=TYPE
33 Read only objects of given type (node, way, relation, change‐
34 set). By default all types are read. This option can be given
35 multiple times.
36
38 -h, --help
39 Show usage help.
40 -v, --verbose
42 Set verbose mode. The program will output information about
43 what it is doing to STDERR.
44 --progress
46 Show progress bar. Usually a progress bar is only displayed if
47 STDOUT and STDERR are detected to be TTY. With this option a
48 progress bar is always shown. Note that a progress bar will
49 never be shown when reading from STDIN or a pipe.
50 --no-progress
52 Do not show progress bar. Usually a progress bar is displayed
53 if STDOUT and STDERR are detected to be a TTY. With this option
54 the progress bar is suppressed. Note that a progress bar will
55 never be shown when reading from STDIN or a pipe.
56
58 -F, --input-format=FORMAT
59 The format of the input file(s). Can be used to set the input
60 format if it can’t be autodetected from the file name(s). This
61 will set the format for all input files, there is no way to set
62 the format for some input files only. See osmium-file-for‐
63 mats(5) or the libosmium manual for details.
64
66 -f, --output-format=FORMAT
67 The format of the output file. Can be used to set the output
68 file format if it can’t be autodetected from the output file
69 name. See osmium-file-formats(5) or the libosmium manual for
70 details.
71 --fsync
73 Call fsync after writing the output file to force flushing buf‐
74 fers to disk.
75 --generator=NAME
77 The name and version of the program generating the output file.
78 It will be added to the header of the output file. Default is
79 “osmium/” and the version of osmium.
80 -o, --output=FILE
82 Name of the output file. Default is `-' (STDOUT).
83 -O, --overwrite
85 Allow an existing output file to be overwritten. Normally
86 osmium will refuse to write over an existing file.
87 --output-header=OPTION=VALUE
89 Add output header option. This command line option can be used
90 multiple times for different OPTIONs. See the libosmium manual
91 for a list of available header options. For some commands you
92 can use the special format “OPTION!” (ie. an exclamation mark
93 after the OPTION and no value set) to set the value to the same
94 as in the input file.
95
97 osmium cat exits with exit code
98 0 if everything went alright,
100 1 if there was an error processing the data, or
102 2 if there was a problem with the command line arguments.
104
106 osmium cat does all its work on the fly and doesn’t keep much data in
107 main memory.
108
110 Convert a PBF file to a compressed XML file:
111 osmium cat -o out.osm.bz2 in.osm.pbf
113 Concatenate all change files in the `changes' directory into one:
115 osmium cat -o all-changes.osc.gz changes/*.osc.gz
117 Copy nodes and ways from source to destination file:
119 osmium cat -o dest.osm.pbf source.osm.pbf -t node -t way
121 Remove changeset, uid, and user from a file to protect personal data:
123 osmium cat -c changeset -c uid -c user -o cleaned.osm.pbf data.osm.pbf
