6 osmium-tags-count - count keys/tags
7
9 osmium tags-count [OPTIONS] OSM-FILE [TAG-EXPRESSION...]
10 osmium tags-count [OPTIONS] --expressions=FILE OSM-FILE
11
13 Count how often keys or tags appear in the input file. If the only
14 command line argument is an OSM file, all keys in this file are
15 counted. If there are one or more tag expressions on the command line,
16 only the keys and tags matching those expressions are counted.
17 See the TAG EXPRESSIONS section for a description of the expression
19 format.
20 The output has one line per key/tag found. Each line contains the
22 count, the tag key, and the tag value (if matching tags) separated by
23 TAB characters. Tag keys and values are surrounded by double quotes.
24 Any double quotes in the keys and values are doubled.
25
27 -e FILE, --expressions=FILE
28 Read expressions from the specified file, one per line. Empty
29 lines are ignored. Everything after the comment character (#)
30 is also ignored. See the TAG EXPRESSIONS section for further
31 details.
32 -m COUNT, --min-count=COUNT
34 The minimum count that should be in the output. Used when you
35 are only interested in common keys/tags.
36 -M COUNT, --max-count=COUNT
38 The maximum count that should be in the output. Used when you
39 are only interested in rare keys/tags.
40 -s SORT, --sort=SORT
42 Sort order. Order by “count-asc”, “count-desc”, “name-asc”, or
43 “name-desc”. Default is “count-desc”.
44 -t, --object-type=TYPE
46 Read only objects of given type (node, way, relation). By de‐
47 fault all types are read. This option can be given multiple
48 times.
49
51 -h, --help
52 Show usage help.
53 -v, --verbose
55 Set verbose mode. The program will output information about
56 what it is doing to STDERR.
57 --progress
59 Show progress bar. Usually a progress bar is only displayed if
60 STDOUT and STDERR are detected to be TTY. With this option a
61 progress bar is always shown. Note that a progress bar will
62 never be shown when reading from STDIN or a pipe.
63 --no-progress
65 Do not show progress bar. Usually a progress bar is displayed
66 if STDOUT and STDERR are detected to be a TTY. With this option
67 the progress bar is suppressed. Note that a progress bar will
68 never be shown when reading from STDIN or a pipe.
69
71 -F, --input-format=FORMAT
72 The format of the input file(s). Can be used to set the input
73 format if it can’t be autodetected from the file name(s). This
74 will set the format for all input files, there is no way to set
75 the format for some input files only. See osmium-file-for‐
76 mats(5) or the libosmium manual for details.
77
79 -o, --output=FILE
80 Name of the output file. Default is `-' (STDOUT).
81 -O, --overwrite
83 Allow an existing output file to be overwritten. Normally os‐
84 mium will refuse to write over an existing file.
85
87 A filter expression specifies one or more keys and/or tags that should
88 be counted in the data.
89 Some examples:
91 amenity
93 Matches the key “amenity”.
94 highway=primary
96 Matches the tag with key “highway” and value “primary”.
97 highway!=primary
99 Matches any tag with key “highway” and a value other than “pri‐
100 mary”.
101 type=multipolygon,boundary
103 Matches any tag with key “type” and value “multipolygon” or
104 “boundary”.
105 name,name:de=Kastanienallee,Kastanienstrasse
107 Matches any tag with the key “name” or “name:de” with the value
108 “Kastanienallee” or “Kastanienstrasse”.
109 addr:* Matches tags with keys starting with “addr:”
111 name=*Paris
113 Matches all tags with key “name” and a value that contains the
114 word “Paris”.
115 If there is no equal sign (“=”) in the expression only keys are matched
117 and values can be anything. If there is an equal sign (“=”) in the ex‐
118 pression, the key is to the left and the value to the right. An excla‐
119 mation sign (“!”) before the equal sign means: A tag with that key, but
120 not the value(s) to the right of the equal sign. A leading or trailing
121 asterisk (“*”) can be used for substring or prefix matching, respec‐
122 tively. Commas (“,”) can be used to separate several keys or values.
123 All filter expressions are case-sensitive. There is no way to escape
125 the special characters such as “=”, “*” and “,”. You can not mix
126 comma-expressions and “*”-expressions.
127 The filter expressions specified in a file and/or on the command line
129 are matched in the order they are given. To achieve best performance,
130 put expressions expected to match more often first.
131
133 osmium tags-count exits with exit code
134 0 if everything went alright,
136 1 if there was an error processing the data, or
138 2 if there was a problem with the command line arguments.
140
142 osmium tags-count keeps all counters in memory. For a large OSM file
143 and unrestricted keys or, worse, tags, this can use quite a lot of mem‐
144 ory. (Counting all tags on a full planet file will use about 16 GByte
145 RAM.)
146 Use the filter expressions to restrict the counting to the keys or tags
148 you are actually interested in.
149
151 Count all keys in Spain and display most common keys first:
152 osmium tags-count spain.osm.pbf
154 Count all building keys in Madrid:
156 osmium tags-count madrid.osm.pbf building
158 Count all building tags on ways in Madrid, order by name:
160 osmium tags-count -t way --sort=name-asc madrid.osm.pbf 'building=*'
162 Count all relation types in Sevilla that appear at least 100 times:
164 osmium tags-count -t relation -m 100 sevilla.osm.pbf 'type=*'
166 Count all tags in the input file. Note that this might need quite a
168 lot of memory!
169 osmium tags-count input.osm.pbf '*=*'
