NAME

       pyosmium-up-to-date - Bring OSM files up-to-date

USAGE

   pyosmium-up-to-date.py
       Update an OSM file with changes from a OSM replication server.

       Diffs  are downloaded and kept in memory. To avoid running out of memory, the maximum size
       of diffs that can be downloaded at once is limited to 1 GB per default.  This  corresponds
       to  approximately  3  days  of update.  The limit can be changed with the –size parameter.
       However, you should take into account that processing the files requires additional memory
       (about 1GB more).

       The  starting  time is automatically determined from the data in the file.  For PBF files,
       it is also possible to read  and  write  the  replication  information  from  the  osmosis
       headers.  That  means that after the first update, subsequent calls to pyosmium-up-to-date
       will continue the updates from the same server exactly where they have left of.

       This program can update normal OSM data files as well as OSM history  files.   It  detects
       automatically on what type of file it is called.

       The  program returns 0, if updates have been successfully applied up to the newest data or
       no new data was available. It returns 1, if some updates have been applied  but  there  is
       still  data  available  on  the  server (either because the size limit has been reached or
       there was a network error which could not be resolved).  Any  other  error  results  in  a
       return code larger than 1.  The output file is guaranteed to be unmodified in that case.

       Some   OSM   data   sources   require  a  cookie  to  be  sent  with  the  HTTP  requests.
       Pyosmium-up-to-date does not fetch the cookie from these services for  you.   However,  it
       can  read  cookies from a Netscape-style cookie jar file, send these cookies to the server
       and will save received cookies to the jar file.

          usage: pyosmium-up-to-date [options] <osm file>

       <osm file>
              OSM file to update

       -h, --help
              show this help message and exit

       -v     Increase verbosity (can be used multiple times)

       -o <outfile>, --outfile <outfile>
              Name output of file. If missing, the input file will be overwritten.

       --format <format>
              Format the data should be saved in.

       --server <server_url>
              Base      URL      of      the      replication      server.      Default:       ‘‐
              https://planet.osm.org/replication/hour/’ (hourly diffs from osm.org).

       -s <size>, --size <size>
              Maximum size of change to apply at once in MB. Default: 1GB.

       --tmpdir <tmpdir>
              Directory to use for temporary files. Default: directory of input file

       --ignore-osmosis-headers
              Ignore potential replication information in the header of the input file and search
              for the newest OSM object in the file instead.

       -b <wind_back>, --wind-back <wind_back>
              Number of minutes to start downloading before the newest addition  to  input  data.
              (Ignored when the file contains a sequence ID.) Default: 60.

       --force-update-of-old-planet
              Apply update even if the input data is really old.

       --cookie <cookie>
              Netscape-style cookie jar file to read cookies from and where
                                            received cookies will be written to.

       --socket-timeout <socket_timeout>
              Set timeout for file downloads.

       --version
              show program’s version number and exit
