RASTER (ARCS) CHARTS

ARCS Charts

Approximately 2,700 ARCS charts are available on 11 chart CD-ROMs, covering the
world's major trading routes and ports. Regionally based chart CD-ROMs RC1 to
RC10 contain standard BA navigation charts, while RC11 contains ocean charts at
scales of 1:3,500,000 and smaller. ARCS charts are facsimile copies of BA paper
charts, and as such share a common numbering system. New editions and new charts
for ARCS and BA paper charts are issued simultaneously. They are supplied on each
Weekly Update CD-ROM until incorporated into the chart CD-ROMs at the next issue.
Occasionally, it is necessary to issue new charts in advance of their intended date of
validity, for example a change in regulations commencing on a future date. In such
cases the current chart will co-exist with the new chart until the date of implementation,
the earlier chart having the suffix "X" after the chart number. The system will allow ac-
cess to both charts for the period of overlap by issue of new chart permits.
Sometimes you may wish to manually add Notices to Mariners or Navtex warnings into
your ARCS charts. In this system this is called Manual Updates. Manual updates are
valid for both ARCS and S57 charts so that you need to define them only once. Fur-
ther, manual updates are valid for all scales so that you don't need to repeat them for
charts published in different scales from the same area.
