NAME

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

USAGE

       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.

       The program returns 0, if updates have been successfully applied up to the newest data. 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.

       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

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

       --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.
