4.3.3 Info / Select − ARCS − Chart Type
Info about ARCS Chart Type
ARCS means Admiralty Raster Chart Service. This institution scans seacharts of
the British Admiralty (BA) in a raster−data−format. Such a manner scanned
seacharts are available on CD−ROM as Raster Nautical Charts (RNCs) with a
worldwide coverage.
A periodical update−service of the ARCS −seacharts is ensured by the
manufacturer.
A seachart in raster−data−format is divided into pixels and then stored.
On the screen of the ECDIS these pixels will be displayed.
In this way the complete (paper−) chart equivalent is displayed on the screen.
As additional information only the geographically coordinates are displayed (after
selection by courser) on the Information Panel.
Other, for seacharts typically information, as there are buoys, light beacons,
wrecks or depth information can only be read out of the displayed seachart.
There is no object query possible on Raster charts.
