Invert Options

Shared Edges

This option will create a border in which the grid cells between the masked and unmasked area are in contact with each other. The two zone will touch each other.

Mutually Exclusive

This option will create a border in which the grid cells between the masked and unmasked area have a buffer zone between them. The two zones do not touch each other.

Grid Selection

Browse for files using the Browse... button, or use the interface showing the available grid files in the current working directory.

Click on the names of the files you want to select. Use the buttons to go to the last folder visited, go up one level, or change the way details are viewed in the window.

  • To highlight multiple consecutive files in the list, hold down the Shift key and click the first and last file names in that section of the list.

  • To highlight multiple non-consecutive files, hold down the Ctrl key while clicking the file names.

Move the items to the selection list on the right side of the panel.

  • Click the button to move the highlighted items to the selection list on the right.

  • Click the button to remove the highlighted items from the selection list on the right.

  • Click the button to move all items to the selection list on the right.

  • Click the button to remove all items from the selection list on the right.

Wildcard

Enter the text to use as a filter, then press Enter. Use * for multiple characters or % to replace a single character.

Example:  For example, with topo_* used as a wildcard, the result might be topo _area2_aerial, topo _min, or topo _with_pit.

Save grid(s) to folder

Use this option to save the resulting masked grid to a specified folder.

Overwrite existing file(s)

Select this option to overwrite any existing files with the same name.

Note:   If a file of the same name already exists in the destination folder and you have not given permission for it to be overwritten, a new mask grid will not be generated.
