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
