Ubuntu Manpage: osmium-add-locations-to-ways - add node locations to ways in OSM file

NAME

       osmium-add-locations-to-ways - add node locations to ways in OSM file

SYNOPSIS

       osmium add-locations-to-ways [OPTIONS] OSM-FILE...

DESCRIPTION

Usually only nodes have locations and the ways refer to those locations via the IDs of the
nodes. This program will copy the input file(s) to the output, taking the locations from
the nodes and adding them to the ways. This makes it easier for other programs to
assemble the way geometries.

The input file must contain all nodes needed for the ways, otherwise there will be an
error. You can change this behaviour using the --ignore-missing-nodes option.

Nodes without any tags will not be copied (unless the --keep-untagged-nodes/-n option is
used). The size of the output file will be similar or a bit smaller than the input file
(unless the --keep-untagged-nodes/-n option is used in which case it will be a lot
bigger).

Note that the OSM files generated by this command use a format extension. Most programs
reading OSM files will not understand this extension and should ignore the extra data.

The osmium add-locations-to-ways command has to keep an index of the node locations in
memory or in a temporary file on disk while doing its work. There are several different
ways it can do that which have different advantages and disadvantages. The default is
good enough for most cases, but see the osmium-index-types(5) man page for details.

If the --keep-untagged-nodes/-n option is used, files created by this command can be
updated with the apply-changes command using the --locations-on-ways option.

This command will not work on full history files.

The command will work with negative IDs (unless the option –keep-member-nodes is used).
The index types for positive IDs and negative IDs are set separately with the --index-
type/-i and --index-type-neg options, respectively.

This commands reads its input file(s) only once (unless the –keep-member-nodes option is
used) and writes its output file in one go so it can be streamed, ie. it can read from
STDIN and write to STDOUT. The input file must be sorted in the usual order: first nodes,
then ways, then relations, objects of each type ordered by id. If there are multiple
input files, they will be read in the order specified on the command line. They must
together have the correct order, so, for instance, the first one can have all the sorted
nodes, the second all the sorted ways, etc. If this is not the case use osmium merge on
the inputs first.

OPTIONS

       -i, --index-type=TYPE
              Set the index type for positive IDs.  For details see the osmium-index-types(5) man
              page.

       --index-type-neg=TYPE
              Set the index type for negative IDs.  For details see the osmium-index-types(5) man
              page.

       -I, --show-index-types
              Shows a list of available index types.  For details see  the  osmium-index-types(5)
              man page.

       -n, --keep-untagged-nodes
              Keep the untagged nodes in the output file.

       --keep-member-nodes
              Keep the nodes that are referenced from relations.  If this option is specified the
              input file(s) are read twice.  Note that the nodes kept when this option is set are
              a strict subset of the nodes kept when –keep-untagged-nodes is set, so setting both
              options is unnecessary.

       --ignore-missing-nodes
              If this is not set a missing node needed for a way results in an error.  If this is
              set,  errors  are  ignored  and  the  way will have an invalid location set for the
              missing node.

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

       -f, --output-format=FORMAT
              The format of the output file.  Can be used to set the output  file  format  if  it
              can’t be autodetected from the output file name.  See osmium-file-formats(5) or the
              libosmium manual for details.

       --fsync
              Call fsync after writing the output file to force flushing buffers to disk.

       --generator=NAME
              The name and version of the program generating the output file.  It will  be  added
              to the header of the output file.  Default is “osmium/” and the version of osmium.

       -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.

       --output-header=OPTION=VALUE
              Add output header option.  This command line option can be used multiple times  for
              different  OPTIONs.   See  the  osmium-output-headers(5)  man  page  for  a list of
              available header options.  For  some  commands  you  can  use  the  special  format
              “OPTION!”  (ie.   an exclamation mark after the OPTION and no value set) to set the
              value to the same as in the input file.

DIAGNOSTICS

       osmium add-locations-to-ways 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 add-locations-to-ways will usually keep all node locations in memory.   For  larger
       data files, this can need several tens of GBytes of memory.  See the osmium-index-types(5)
       man page for details.

EXAMPLES

       Add node locations to an extract keeping all nodes:

              osmium add-locations-to-ways -n -o germany-low.osm.pbf germany.osm.pbf

       Add node locations to a planet file (without untagged nodes):

              osmium add-locations-to-ways -i dense_mmap_array -o planet-low.osm.pbf planet.osm.pbf
