include only a subset of the data
To create a mask

contains the area that you do not want masked (i.e. on which the mask
will be built around)
- Choose Tools-Geographic Utilities-Mask to
display the Create a Mask dialog box.
- Choose the selection set that you created in step 2 from the
Selection drop-down list.
- Type a name for the new mask layer.
