retain 0.2

Removes all tiles that lie outside the specified area or bounding box.

Usage:

gol retain <gol-file> [<options>]  

Options

-a, --area=<FILE>

Defines the area to which the command should be applied. Currently, only polygon files are supported.

-b, --bbox=<W>,<S>,<E>,<N>

Defines the rectangular area (bounding box) to which the command should be applied. Coordinates are specified in WGS-84 (degrees longitude and latitude) and take the form <west>,<south>,<east>,<north>. Coordinates must not be separated by spaces (otherwise, they would be interpreted as separate arguments).

As an alternative, this option accepts a tile descriptor in the form z/x/y.

-q, --quiet

Displays only minimal output. Apart from error messages, only minimal progress updates are written to stderr.

-s, --silent

No output at all is written to stderr, not even error messages. (Whether a command succeeded or failed can only be ascertained via the status code returned by the process).

-v, --verbose

Writes extra information to stderr.
