# r.unpack

Imports a GRASS specific raster archive file (packed with r.pack) as a raster map

=== "Command line"

    **r.unpack**
    [**-op**]
    **input**=*name.pack*
    [**output**=*name*]
    [**--overwrite**]
    [**--verbose**]
    [**--quiet**]
    [**--qq**]
    [**--ui**]

    Example:

    ```sh
    r.unpack input=name.pack
    ```

=== "Python (grass.tools)"

    *grass.tools.Tools.r_unpack*(**input**,
        **output**=*None*,
        **flags**=*None*,
        **overwrite**=*None*,
        **verbose**=*None*,
        **quiet**=*None*,
        **superquiet**=*None*)

    Example:

    ```python
    tools = Tools()
    tools.r_unpack(input="name.pack")
    ```

    This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.

    *grass.script.run_command*("***r.unpack***",
        **input**,
        **output**=*None*,
        **flags**=*None*,
        **overwrite**=*None*,

        **quiet**=*None*,
        **superquiet**=*None*)

    Example:

    ```python
    gs.run_command("r.unpack", input="name.pack")
    ```

## Parameters

    **-o**  
    &nbsp;&nbsp;&nbsp;&nbsp;Override projection check (use current projects's CRS)  
    &nbsp;&nbsp;&nbsp;&nbsp;Assume that the dataset has same coordinate reference system as the current project  
    **-p**

    **--qq**  
    &nbsp;&nbsp;&nbsp;&nbsp;Very quiet module output  
    **--ui**  
    &nbsp;&nbsp;&nbsp;&nbsp;Force launching GUI dialog

=== "Python (grass.tools)"

    **input** : str, *required*  
    &nbsp;&nbsp;&nbsp;&nbsp;Name of input pack file  
    &nbsp;&nbsp;&nbsp;&nbsp;Used as: input, file, *name.pack*  
    **output** : str | type(np.ndarray) | type(np.array) | type(gs.array.array), *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Name for output raster map (default: taken from input file internals)  
    &nbsp;&nbsp;&nbsp;&nbsp;Used as: output, raster, *name*  
    **flags** : str, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Allowed values: *o*, *p*  
    &nbsp;&nbsp;&nbsp;&nbsp;**o**  
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Override projection check (use current projects's CRS)  
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Assume that the dataset has same coordinate reference system as the current project  
    &nbsp;&nbsp;&nbsp;&nbsp;**p**  
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Print projection information of input pack file and exit  
  
    **overwrite** : bool, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Allow output files to overwrite existing files  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*  
    **verbose** : bool, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Verbose module output  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*  
    **quiet** : bool, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Quiet module output  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*  
    **superquiet** : bool, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Very quiet module output  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*  

    Returns:

    **result** : grass.tools.support.ToolResult | np.ndarray | tuple[np.ndarray] | None  
    If the tool produces text as standard output, a *ToolResult* object will be returned. Otherwise, `None` will be returned. If an array type (e.g., *np.ndarray*) is used for one of the raster outputs, the result will be an array and will have the shape corresponding to the computational region. If an array type is used for more than one raster output, the result will be a tuple of arrays.

    Raises:

    *grass.tools.ToolError*: When the tool ended with an error.

## DESCRIPTION

*r.unpack* allows unpacking raster maps packed by *[r.pack](r.pack.md)*.

## NOTES

Name of the raster map is determined by default from pack file
internals. Optionally the name can be given by **output** parameter.
Currently only 2D raster maps are supported.

## EXAMPLE

Pack up raster map *aspect* into *aspect.pack* file.

```sh
r.pack input=aspect
```

the raster map can be afterwards unpacked by

```sh
r.unpack input=aspect.pack
```
