Seamless ENC/ARCS
It is possible to display the best chart coverage for the area using all available chart
collections. In general the ENC, AVCS and ARCS can be displayed at the same time if
ENC
+AVCS
and
with ARCS
are ticked on.
If ARCS charts are installed together with ENC the chart on the screen can be displayed in
seamless mode, meaning that for the area of the screen not covered by ENC charts, ARCS
charts is used to complete the pictures.
Display strategy
When ENC cells do not cover whole screen, ECDIS900 looks for an ARCS chart with the
closest scale within the limits of 4 times the current scale. ARCS chart is then eventually
shifted according to its datum and zoomed according to the scale in use.
If no ARCS chart is found the general ENC background chart is used to complete the
coverage.
