The Clipping operation is used to crop one or more region of interest and create a new layer.
It is accessible through:

   Raster Processing > Clipping... (list of all raster layers will be available) 

This wizard consists of the following steps:

    Wizard Page 1 - Selection of the layer to apply the clipping operation (Layer Search)

1. On the List of Layers select the raster layer to clipping. 
2. Optionally use Filter By Name field giving part of the layer name to help find the layer in the list.
3. Press Next  to go to next step or Cancel to close the dialog. 

1. Type: select the type of clipping to be used and set the their specific parameters as explained bellow:

• Region of interest (ROI): Use the tools    or to define one or more rectangular or polygonal ROI over the image.  Use also () to delete  any ROI previously defined.  
• By default all ROIs are selected, however it is possible to select some of then by clicking over it.
• Unique Image: is the default option.  
• Multi Image: it will generetad one Raster for each ROI, with a suffix number at the the Output layer name.
  

• Layer Extent: Select the layer (use Apply button to see the overlapping region defined by the original bbox of the layer). Specify a new bbox (changing the parameters) if desired and use Apply again to see the overlapping region over the image.
• Lower Left X
• Lower Left Y
• Upper Right X
• Upper Right Y

• Layer: The user uses geometries from a vectorial layer to crop the raster.
• Layer: Select the vector layer desired and define how to crop, selecting:
• Aggregate all geometries: Use all geometries from layer to crop the raster, generating only one raster.
• Group by Attribute: Uses a specific attribute from layer to group the geometries to crop the raster, generating one raster for each group (Ex.: group Layer of municipalities by attr state -> will generate one image for each state)
• Use selected geometries: First draw the Vector layer over the image to be cropped at the Map Display and select one or more geometries, and then use this option 

• Dimension:  Informe the upper left  row and upper left column desired (Upper Left corner is 0,0) and also sets the height and width to crop the raster. Hint: Use Info tool from the menu bar to check the desired coordinates.
• Initial Row
• Initial Column
• Height (number of rows from the initial row)
• Width (number of rows from the initial column)

• Press Next  or Back to go to the previous wizard page. 

    Wizard Page 3 - Output information

1. Raster Info - First press and inform the folder where the resulting file will be saved.
2. Name - inform the raster name.
3. Extra Parameters - if there are some, see the details on how to inform then here.
4. Press Finish to save the resulting contrasted raster or Back to go to the previous wizard page.

Hint: The clipping image(s) will be added as a new layer(s) at the TerraView project.
