6.11.1 Sidescan Blink Comparator

To quickly compare two overlapping sidescan mosaic layers, the 'Blink Comparator' tool can
be used. The 'Blink Comparator' allows the user to quickly turn on/off a layer or can be set to
cycle a layer on/off to help identify differences in the layers.

To use the 'Blink Comparator' tool, right-click on the mosaic you wish to "Blink" (cycle on
and off) and select 'Blink Comparator' from the menu options as shown below:

Selecting the 'Blink Comparator' menu option, the following window will open:

The options available in the 'Blink Comparator' include:

Layer On: This will turn the selected layer on in the file tree so the layer is displayed in the
map view.

Layer Off: This will turn the selected layer off in the file tree so the layer is not displayed in
the map view.

Cycle: This will turn the cycle the layer on and off in the map view at the user set frequency
using the slider bar to the right the Cycle option.

An example of the use of this tool is presented on the following page. The top image is with
the selected layer off so the user can see the layer underneath. The next image shows the
selected layer cycled on showing an object on the bottom surface that was not present in the
previously collected data.
