OSM2PGSQL(1)

NAME
osm2pgsql-expire - Visualize expire output

SYNOPSIS
osm2pgsql-expire [OPTIONS] OSM-FILE (1) osm2pgsql-expire TILES-FILE (2)

DESCRIPTION
This command is currently experimental.

The expire command can be used for two things:

1.  To check what tiles some OSM data is in. If an OSM-FILE is specified osm2pgsql-expire will calculate the tiles covering the objects in that file. Note that the file must not be a change file but a regular OSM data file! Output is, by default, a tile file, but GeoJSON is also possible.

2.  Visualize tile list. If a TILE-FILE (presumably generated by osm2pgsql) is specified, a GeoJSON file is generated showing all mentioned tiles. In this mode all command line options are ignored.

Read the Expire chapter of the osm2pgsql manual (https://osm2pgsql.org/doc/manual.html#expire) for details on how to interpret the -m, \--mode and \--full-area-limit options.

OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (--). Mandatory arguments to long options are mandatory for short options too.

MAIN OPTIONS

-b, --buffer=VALUE
    Set buffer size around geometry relative to tile size. Example: Set to 0.1 for a buffer that’s 10% of the tile size.

-f, --format=FORMAT
    Output format. Options are `tiles' (default) or `geojson'. The GeoJSON output uses the Web Mercator projection (EPSG:3857) which is supported by many programs although, strictly speaking, it is not allowed by the GeoJSON spec.

--full-area-limit=VALUE
    Set full area limit.

-m, --mode=MODE
    Set expire mode. One of boundary_only, full_area (default), and hybrid.

-z, --zoom=ZOOM
    Zoom level on which to calculate tiles.

HELP/VERSION OPTIONS

-h, --help
    Print help.

-V, --version
    Print osm2pgsql version.

LOGGING OPTIONS

--log-level=LEVEL
    Set log level (`debug', `info' (default), `warn', or `error').
