       osmupdate - Update OSM files


       osmupdate options [oldfile] [newfile]


       This  program  cares about updating an .osm, .o5m or .pbf file. It will download and apply
       OSM Change files (.osc) from the  servers  of  "".   It  also  can
       assemble a new .osc or .o5c file which can be used to update your OSM data file at a later

       If there is no file timestamp available within your input file, you need  to  specify  the
       appropriate timestamp manually. In this case, it is recommended to pick a timestamp of one
       or two days earlier than necessary, just to be on the save side.


       To run this program, please download and install two other  programs  first:  "osmconvert"
       and "wget".


       Two  command line arguments are mandatory: the name of the old and the name of the new OSM
       data file. If the old data file does not have a file timestamp, you may  want  to  specify
       this  timestamp  manually  on  the  command  line.  If you do not, the program will try to
       determine the timestamp by examining the whole old  data  file.   Instead  of  the  second
       parameter, you alternatively may specify the name of a change file (.osc or .o5c). In this
       case, you also may replace the name of the old OSM data file by a timestamp.  Command line
       arguments  which  are  not  recognized by osmupdate will be passed to osmconvert. Use this
       opportunity to supply a bounding box or a bounding polygon if you are going  to  update  a
       regional change file. You also may exclude unneeded meta data from your file by specifying
       this osmconvert option: --drop-author


       The program osmupdate recognizes a few command line options:


              By default, the maximum time range for to assemble a cumulated  changefile  is  250
              days. You can change this by giving a different maximum number of days, for example
              300.  If you do, please ensure that there are daily change files available for such
              a wide range of time.

       --minute --hour --day --sporadic

              By default, osmupdate uses a combination of minutely, hourly and daily changefiles.
              If you want to limit these changefile categories, use one or two of  these  options
              and choose that category/ies you want to be used.  The option --sporadic allows one
              to process changefile sources which do not have  the  usual  "minute",  "hour"  and
              "day" subdirectories.


              The  subprogram  osmconvert  is able to merge more than two changefiles in one run.
              This ability increases merging speed.   Unfortunately,  every  changefile  consumes
              about  200  MB of main memory while being processed. For this reason, the number of
              parallely processable changefiles is limited.  Use  this  commandline  argument  to
              determine  the maximum number of parallely processed changefiles. The default value
              is 7.

       -t=TEMPPATH --tempfiles=TEMPPATH

              On order to cache changefiles, osmupdate needs a separate directory. This parameter
              defines  the  name of this directory, including the prefix of the tempfiles' names.
              The default value is "osmupdate_temp/temp".


              Use this option if you want to keep local copies of every downloaded file. This  is
              strongly  recommended  if  you  are  going  to assemble different changefiles which
              overlap in time ranges. Your data traffic will be minimized.  Do  not  invoke  this
              option  if  you are going to use different change file sources (option --base-url).
              This would cause severe data corruption.


              Define level for gzip compression. Values between 1 (low compression, but fast) and
              9 (high compression, but slow).


              To  accelerate  downloads  or  to  get  regional  file  updates  you may specify an
              alternative download location. Please enter its URL, or simply the word "mirror" if
              you want to use gwdg's planet server.


              To  use old planet URLs, you may need to add the suffix "-replicate" because it was
              custom to have this word in the URL, right after the period identifier "day" etc.

       -v --verbose

              With activated 'verbose' mode, some statistical data and  diagnosis  data  will  be
              displayed.   If  -v  resp.  --verbose is the first parameter in the line, osmupdate
              will display all input parameters.


       This program is for experimental use. Expect malfunctions and data loss. Do  not  use  the
       program in productive or commercial systems.

       osmupdate old_file.o5m new_file.o5m
       osmupdate old_file.pbf new_file.pbf
       osmupdate old_file.osm new_file.osm

              The old OSM data will be updated and written as new_file.o5m or  new_file.o5m.  For
              safety  reasons  osmupdate  will  not delete the old file. If you do not need it as
              backup file, please delete it by yourself.

              osmupdate old_file.osm 2011-07-15T23:30:00Z new_file.osm
              osmupdate old_file.osm NOW-86400 new_file.osm

              If your old OSM data file does not contain a file timestamp, or you do not want  to
              rely on this timestamp, it can be specified manually. Relative times are in seconds
              to NOW.

              osmupdate old_file.o5m change_file.o5c
              osmupdate old_file.osm change_file.osc
              osmupdate 2011-07-15T23:30:00Z change_file.o5c
              osmupdate 2011-07-15T23:30:00Z change_file.osc.gz
              osmupdate NOW-3600 change_file.osc.gz

              Here, the old OSM data file is not updated directly. An OSM changefile  is  written
              instead.  This  changefile can be used to update the OSM data file afterwards.  You
              will have recognized the extension .gz in the last example. In this case,  the  OSM
              Change  file will be written with gzip compression. To accomplish this, you need to
              have the program gzip installed on your system.

              ./osmupdate london_old.o5m london_new.o5m -B=london.poly

              The OSM data  file  london_old.o5m  will  be  updated.  Hence  the  downloaded  OSM
              changefiles  contain  not only London, but the whole planet, a lot of unneeded data
              will be added to this regional file. The -B= argument will clip  these  superfluous
