BACKGROUND IMAGE ADJUSTMENTS
As mentioned previously, the file tree order controls the order of files displayed in the map
view. The tiffs located higher in the file tree structure are shown on top of those lower in
the file tree. In this example the sidescan tiff is on top of the aerial photo, which is
displayed over the background topo.
There are a few options in SB-Interpreter that can make these images more useful for spatial
referencing. By right-clicking on the individual tiffs, the file tree order and transparency
settings can be changed.
One of the more obvious changes needed is to remove the ‘no data’ region of the sidescan tiff.
If we decide we want the chart (topo) to overlay the aerial photo, we can either move the
photo down in the list or move the chart up the list and also change its transparency so we can
still view the aerial photo now located beneath it.
