Appendix C: C-MAP Chart Card Features
The C_MAP chart cards display cartographic features which are derived from a
library of symbols. The library includes a set of 16 x 16 pixel bitmaps which
provide realistically shaped icons for many chart objects. However, these
complex icons can overlap and clutter the display at some scales, so it possible
for the user to select smaller, simple icons. Some chart objects are represented
by text; in such cases conventional abbreviated text is used, for example, M –
mud, Sh – shingle, R – rock.
The chartplotter RC520 and RL70RC set up menu provides the sub-menu
CUSTOMISE CHART, which lets you determine how chart features are displayed.
You can set the icon display of many features to custom; you then use the
CUSTOM soft key to switch the customised icons off/on. The factory default for
the CUSTOM options is on.
The chart features controlled from the Customise Chart menu are grouped as
detailed below, some groups are sub-divided into categories
