Note: AIS and tracked target viewing limitations are as follows:
• AIS and tracked targets are displayed on top of chart 1:1,000,001 for S57 charts.
• AIS and tracked targets are displayed on top of chart 1:1,900,001 for ARCS charts. This allows display
of AIS and tracked targets on top of the largest scale ocean charts (original scale 1:3,500,000) when
they are zoomed to "overscale".
The left illustration shows the cal signs of targets and the right illustration shows the names of targets.
