NAME

6       osmium-renumber - renumber object IDs
7

SYNOPSIS

9       osmium renumber [OPTIONS] OSM-DATA-FILE
10

DESCRIPTION

12       The objects (nodes, ways, and relations) in an OSM file often have very
13       large IDs.  This can make some kinds of postprocessing difficult.  This
14       command will renumber all objects using IDs starting at 1.  Referential
15       integrity will be kept.  All objects which appear in  the  source  file
16       will be in the same order in the output file.  IDs of objects which are
17       not in the file but referenced from ways or relations are  not  guaran‐
18       teed to be in the correct order.
19
20       This  command  expects  the  input file to be ordered in the usual way:
21       First nodes in order of ID, then ways in order of ID, then relations in
22       order of ID.  Negative IDs are allowed, they must be ordered before the
23       positive IDs.  See the osmium-sort(1) man page for details of  the  or‐
24       dering.
25
26       The  input file will be read twice, so it will not work with STDIN.  If
27       you are not renumbering relations (ie.  if the option  --object-type/-t
28       is  used  with nodes and/or ways but not relations) the input file will
29       only be read once, so in that case it will work with STDIN.
30
31       To renumber the IDs in several files, call  osmium  renumber  for  each
32       file  and  specify  the --index-directory/-i option each time.  See the
33       INDEX FILES section for more details.
34
35       You must never upload the data generated by this command to  OSM!  This
36       would  really confuse the OSM database because it knows the objects un‐
37       der different IDs.
38

OPTIONS

40       -i, --index-directory=DIR
41              Directory where the index files for mapping between old and news
42              IDs are read from and written to, respectively.  Use this if you
43              want to map IDs in several OSM files.  Without this option,  the
44              indexes  are  not  read  from or written to disk.  The directory
45              must exist.  Use `.' for the current directory.  The files writ‐
46              ten  will  be named nodes.idx, ways.idx, and relations.idx.  See
47              also the INDEX FILES section below.
48
49       --show-index=TYPE
50              Print the content of the index for TYPE (node, way, or relation)
51              on STDOUT.  Each line contains the old ID, a space character and
52              then the new  ID.   Any  other  options  (except  --index-direc‐
53              tory/-i) are ignored if this option is used.
54
55       -s, --start-id=FIRST_ID or FIRST_NODE_ID,FIRST_WAY_ID,FIRST_RELATION_ID
56              Set  the  first  ID that should be used.  If the ID is positive,
57              IDs are counted upwards, if the ID is negative, they are counted
58              downwards.   This can be set to either a single ID which is used
59              for all object types or a comma-separated list of three IDs used
60              for the first node, way, and relation, respectively.  If this is
61              not set, IDs for all object types start at 1.
62
63       -t, --object-type=TYPE
64              Renumber only objects of given type (node,  way,  or  relation).
65              By default all objects of all types are renumbered.  This option
66              can be given multiple times.
67

COMMON OPTIONS

69       -h, --help
70              Show usage help.
71
72       -v, --verbose
73              Set verbose mode.  The program  will  output  information  about
74              what it is doing to STDERR.
75
76       --progress
77              Show  progress bar.  Usually a progress bar is only displayed if
78              STDOUT and STDERR are detected to be TTY.  With  this  option  a
79              progress  bar  is  always  shown.  Note that a progress bar will
80              never be shown when reading from STDIN or a pipe.
81
82       --no-progress
83              Do not show progress bar.  Usually a progress bar  is  displayed
84              if STDOUT and STDERR are detected to be a TTY.  With this option
85              the progress bar is suppressed.  Note that a progress  bar  will
86              never be shown when reading from STDIN or a pipe.
87

INPUT OPTIONS

89       -F, --input-format=FORMAT
90              The  format  of the input file(s).  Can be used to set the input
91              format if it can’t be autodetected from the file name(s).   This
92              will  set the format for all input files, there is no way to set
93              the format for some  input  files  only.   See  osmium-file-for‐
94              mats(5) or the libosmium manual for details.
95

OUTPUT OPTIONS

97       -f, --output-format=FORMAT
98              The  format  of  the output file.  Can be used to set the output
99              file format if it can’t be autodetected  from  the  output  file
100              name.   See  osmium-file-formats(5)  or the libosmium manual for
101              details.
102
103       --fsync
104              Call fsync after writing the output file to force flushing  buf‐
105              fers to disk.
106
107       --generator=NAME
108              The  name and version of the program generating the output file.
109              It will be added to the header of the output file.   Default  is
110osmium/” and the version of osmium.
111
112       -o, --output=FILE
113              Name of the output file.  Default is `-' (STDOUT).
114
115       -O, --overwrite
116              Allow  an  existing output file to be overwritten.  Normally os‐
117              mium will refuse to write over an existing file.
118
119       --output-header=OPTION=VALUE
120              Add output header option.  This command line option can be  used
121              multiple  times  for  different OPTIONs.  See the osmium-output-
122              headers(5) man page for a list of available header options.  For
123              some  commands you can use the special format “OPTION!” (ie.  an
124              exclamation mark after the OPTION and no value set) to  set  the
125              value to the same as in the input file.
126

INDEX FILES

128       When  the  --index-directory/-i  option is specified, index files named
129       nodes.idx, ways.idx, and relations.idx are read from and written to the
130       given directory together with a file called start_ids that contains the
131       start IDs set with --start-id/-s.
132
133       This can be used to force consistent mapping over  several  invocations
134       of  osmium  renumber,  for  instance when you want to remap an OSM data
135       file and a corresponding OSM change file.
136
137       The index files are in binary format, but you can print the indexes  in
138       text format using the --show-index option:
139
140              osmium renumber -i idxdir --show-index node     >nodes-index.txt
141              osmium renumber -i idxdir --show-index way      >ways-index.txt
142              osmium renumber -i idxdir --show-index relation >relations-index.txt
143

DIAGNOSTICS

145       osmium renumber exits with exit code
146
147       0      if everything went alright,
148
149       1      if there was an error processing the data, or
150
151       2      if there was a problem with the command line arguments.
152

MEMORY USAGE

154       osmium  renumber  needs  quite a bit of main memory to keep the mapping
155       between old and new IDs.  It is intended for small to medium sized  ex‐
156       tracts.   You  will  need  more  than  32  GB RAM to run this on a full
157       planet.
158
159       Memory use is at least 8 bytes per node, way, and relation  ID  in  the
160       input file.
161

EXAMPLES

163       Renumber a PBF file and output to a compressed XML file:
164
165              osmium renumber -o ch.osm.bz2 germany.osm.pbf
166
167       Renumbering the about 3.3 GB Germany PBF file currently (February 2020)
168       takes about three minutes and needs about 7 GB RAM.
169
170       Renumber a PBF file starting the node IDs at 1 (and counting  upwards),
171       the  way  IDs  at  100 and the relation IDs at -200 (and counting down‐
172       wards.
173
174              osmium renumber -o renumbered.osm.pbf -s 1,100,-200 athens.osm.pbf
175
176       Renumber an OSM file storing the indexes on disk:
177
178              osmium renumber -i. -o renumbered.osm data.osm
179
180       then rewrite a change file, too:
181
182              osmium renumber -i. -o renumbered.osc changes.osc
