navigation, the previous published Littoral Planning Chart shall
be updated with appropriate Notice to Mariners.
3.4.3 New or new edition. When new or new edition Littoral
Planning Charts are produced and the adjacent charts are not
updated, chart detail in the overlap area shall be identical to
the previously published charts, except as noted in 3.4.2.
3.5 Series. Littoral Planning Charts produced, as part of a
series shall be outlined in a location diagram in the
marginalia of the chart.
3.6 Scale.
3.6.1 Standard Scale. Littoral Planning Charts are generally
constructed at a standard scale of 1:50,000. The linear
dimensions (length, width, area, etc.) expressed in Appendix A
of this specification are based on a map distance to ground
distance ratio of 1:50,000. Linear dimensions for non-standard
scale Littoral Planning Charts as described in 3.6.2 shall be
modified proportionally.
3.6.2 Non-standard scales. Littoral Planning Charts may be
produced at a non-standard scale. The linear dimensions
expressed in Appendix A of this specification are based on the
standard scale of 1:50,000. All dimensions reference in
Appendix A shall be modified proportionally to accommodate non-
standard scale charts.
3.6.3 Data density. The standard 1:50,000 scale of the
Littoral Planning Chart is adhered to even in areas where the
corresponding topographic map coverage is at 1:100,000 scale.
The level of topographic detail and density shown on Littoral
Planning Charts shall commensurate with 1:50,000 scale.
3.7 Chart design.
a. Littoral Planning Charts at a standard scale of
1:50,000 provide chart coverage for 8 to 15 nautical miles of
land distance and 5 to 15 nautical miles of sea distance (total
thirty nautical miles); however, the proportion of the land and
water may vary for special user requirements. The charts shall
be oriented east-west, north-south, or skewed. The long edge of
the Littoral Planning Chart runs generally perpendicular to the
coastline to provide sufficient coverage inland and out to sea.
