DESCRIPTION

       projsync is a program that downloads remote resource files into a local directory. This is
       an alternative to downloading a proj-data-X.Y.Z  archive  file,  or  using  the  on-demand
       networking capabilities of PROJ.

       The following control parameters can appear in any order:

       --endpoint URL
              Defines  the  URL  where  to  download  the  master files.geojson file and then the
              resource files. Defaults to the value set in proj-ini

       --local-geojson-file FILENAME
              Defines the filename for  the  master  GeoJSON  files  that  references  resources.
              Defaults to ${endpoint}/files.geojson

       --user-writable-directory
              Specifies  that  resource  files must be downloaded in the user writable directory.
              This is the default.

       --system-directory
              Specifies    that    resource    files    must     be     downloaded     in     the
              ${installation_prefix}/share/proj  directory.  The  user  launching projsync should
              make sure it has writing rights in that directory.

       --target-dir DIRNAME
              Directory into which resource files must be downloaded.

       --bbox west_long,south_lat,east_long,north_lat
              Specify an area of interest to restrict the resources to  download.   The  area  of
              interest  is  specified as a bounding box with geographic coordinates, expressed in
              degrees in a unspecified geographic CRS.  west_long and east_long should be in  the
              [-180,180]  range,  and  south_lat  and  north_lat  in  the  [-90,90]. west_long is
              generally lower than east_long, except in the  case  where  the  area  of  interest
              crosses the antimeridian.

       --spatial-test contains|intersects
              Specify  how  the  extent  of  the  resource  files are compared to the area of use
              specified explicitly with --bbox.  By default,  any  resource  files  whose  extent
              intersects  the  value specified by --bbox will be selected.  If using the contains
              strategy, only resource files whose extent is contained in the value  specified  by
              --bbox will be selected.

       --source-id ID
              Restrict resource files to be downloaded to those whose source_id property contains
              the ID value. Specifying ? as ID will list all possible values.

       --area-of-use NAME
              Restrict resource files to  be  downloaded  to  those  whose  area_of_use  property
              contains the NAME value. Specifying ? as NAME will list all possible values.

       --file NAME
              Restrict  resource files to be downloaded to those whose name property contains the
              NAME value. Specifying ? as NAME will list all possible values.

       --all  Ask to download all files.

       --exclude-world-coverage
              Exclude files which have world coverage.

       -q / --quiet
              Quiet mode

       --verbose
              New in version 8.1.

              Verbose mode (more than default)

       --dry-run
              Simulate the behavior of the tool without downloading resource files.

       --list-files
              List file names, with the source_id and area_of_use properties.

       --no-version-filtering
              New in version 8.1.

              By  default,  projsync  only  downloads  files   that   are   compatible   of   the
              PROJ_DATA.VERSION  metadata  of  proj.db, taking into account the version_added and
              version_removed properties of  entries  in  files.geojson.   When  specifying  this
              switch,  all  files  referenced  in  files.geojson will be candidate (combined with
              other filters).

       At least one of  --list-files,  --file,  --source-id,  --area-of-use,   --bbox  or   --all
       must be specified.

       Options --file,  --source-id, --area-of-use and --bbox are combined with a AND logic.

EXAMPLES

       1. Download all resource files

          projsync --all

       2. Download resource files covering specified point and attributing to an agency

          projsync --source-id fr_ign --bbox 2,49,2,49
