NAME

       osmium-tags-count - count keys/tags

SYNOPSIS

       osmium tags-count [OPTIONS] OSM-FILE [TAG-EXPRESSION...]
       osmium tags-count [OPTIONS] --expressions=FILE OSM-FILE

DESCRIPTION

       Count how often keys or tags appear in the input file.  If the only command line argument is an OSM file,
       all  keys  in  this file are counted.  If there are one or more tag expressions on the command line, only
       the keys and tags matching those expressions are counted.

       See the TAG EXPRESSIONS section for a description of the expression format.

       The output has one line per key/tag found.  Each line contains the count, the tag key, and the tag  value
       (if  matching  tags)  separated  by TAB characters.  Tag keys and values are surrounded by double quotes.
       Any double quotes in the keys and values are doubled.

OPTIONS

       -e FILE, --expressions=FILE
              Read expressions from the specified file, one per line.   Empty  lines  are  ignored.   Everything
              after  the  comment  character  (#)  is also ignored.  See the TAG EXPRESSIONS section for further
              details.

       -m COUNT, --min-count=COUNT
              The minimum count that should be in the output.  Used when  you  are  only  interested  in  common
              keys/tags.

       -M COUNT, --max-count=COUNT
              The  maximum  count  that  should  be  in  the  output.  Used when you are only interested in rare
              keys/tags.

       -s SORT, --sort=SORT
              Sort order.  Order by “count-asc”, “count-desc”, “name-asc”, or “name-desc”.  Default  is  “count-
              desc”.

       -t, --object-type=TYPE
              Read  only  objects  of  given  type  (node, way, relation).  By default all types are read.  This
              option can be given multiple times.

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.

OUTPUT OPTIONS

       -o, --output=FILE
              Name of the output file.  Default is `-' (STDOUT).

       -O, --overwrite
              Allow an existing output file to be overwritten.  Normally osmium will refuse  to  write  over  an
              existing file.

TAG EXPRESSIONS

A filter expression specifies one or more keys and/or tags that should be counted in the data.

Some examples:

amenity
Matches the key “amenity”.

highway=primary
Matches the tag with key “highway” and value “primary”.

highway!=primary
Matches any tag with key “highway” and a value other than “primary”.

type=multipolygon,boundary
Matches any tag with key “type” and value “multipolygon” or “boundary”.

name,name:de=Kastanienallee,Kastanienstrasse
Matches any tag with the key “name” or “name:de” with the value “Kastanienallee” or
“Kastanienstrasse”.

addr:* Matches tags with keys starting with “addr:”

name=*Paris
Matches all tags with key “name” and a value that contains the word “Paris”.

If there is no equal sign (“=”) in the expression only keys are matched and values can be anything. If
there is an equal sign (“=”) in the expression, the key is to the left and the value to the right. An
exclamation sign (“!”) before the equal sign means: A tag with that key, but not the value(s) to the
right of the equal sign. A leading or trailing asterisk (“*”) can be used for substring or prefix
matching, respectively. Commas (“,”) can be used to separate several keys or values.

All filter expressions are case-sensitive. There is no way to escape the special characters such as “=”,
“*” and “,”. You can not mix comma-expressions and “*”-expressions.

The filter expressions specified in a file and/or on the command line are matched in the order they are
given. To achieve best performance, put expressions expected to match more often first.

DIAGNOSTICS

       osmium tags-count 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  tags-count  keeps  all counters in memory.  For a large OSM file and unrestricted keys or, worse,
       tags, this can use quite a lot of memory.  (Counting all tags on a full planet file  will  use  about  16
       GByte RAM.)

       Use the filter expressions to restrict the counting to the keys or tags you are actually interested in.

EXAMPLES

       Count all keys in Spain and display most common keys first:

              osmium tags-count spain.osm.pbf

       Count all building keys in Madrid:

              osmium tags-count madrid.osm.pbf building

       Count all building tags on ways in Madrid, order by name:

              osmium tags-count -t way --sort=name-asc madrid.osm.pbf 'building=*'

       Count all relation types in Sevilla that appear at least 100 times:

              osmium tags-count -t relation -m 100 sevilla.osm.pbf 'type=*'

       Count all tags in the input file.  Note that this might need quite a lot of memory!

              osmium tags-count input.osm.pbf '*=*'
