Compare and contrast the following overlay techniques: Union, Intersect, Identity, Clip and Erase. What happens to the locations and attributes of data inputs after conducting each of the overlay methods.

Union-Overlay operation that combines the locations and attributes of each layer. All locations and attributes are retained. Intersect-Overlay operation that combines the locations and attributes of each layer, but only where the layers directly overlap with each other. Identity-Overlay operation that identifies the locations where the identity layer overlaps with the base layer. Result creates an output layer in which the geographic area and extent is identical to the base layer and the intersection of the identity layer is recognized. The attributes of the identity layer are added to the output layer. Clip-Clip is an extraction operation that cuts out the features in the input layer that overlay with the clip layer. The clip layer acts as a cookie cutter. The result of this operation creates a new output layer that includes land use features that reside within municipal boundaries. Land uses that fall outside municipal boundaries are discarded. Erase-Erase is an overlay operation that eliminates the features of an input layer where it overlaps with the erase features. The result is new output layer that includes land use features that reside outside the municipal boundaries. Land uses contained inside municipal boundaries are discarded (erased).
