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

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

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

    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
