Seamless ENC/ARCS
DISPLAY STRATEGY
When ENC cells do not cover all the 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.
NOTE
See the ARCS Seaml ess mode for more details
