SYNOPSIS

projsync

[--endpoint URL] [--local-geojson-file FILENAME] ([--user-writable-directory] | [--system-directory] | [--target-dir DIRNAME]) [--bbox west_long,south_lat,east_long,north_lat] [--spatial-test contains|intersects] [--source-id ID] [--area-of-use NAME] [--file NAME] [--all] [--exclude-world-coverage] [--quiet] [--dry-run] [--list-files]



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 behavior 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
