C-MAP specific chart options
Chart overlay, orientation, and look ahead options (previously
described in this section) are common to both C-MAP and
Navionics charts. The following describe C-MAP specific chart
options.
Chart detail
•
Full
All available information for the chart in use.
•
Medium
Minimum information sufficient for navigation.
•
Low
Basic level of information that cannot be removed, and includes
information that is required in all geographic areas. It is not
intended to be sufficient for safe navigation.
Depth palette
Controls the Depth palette used on the map.
Depth filter
Filters out depth values shallower than the selected depth filter
limit.
Safety depth
C-MAP charts use different shades of blue to
distinguish between shallow (lighter shades) and deep (darker
shades) water. After enabling Safety depth, specify the
desired safety depth limit. The Safety depth sets the limit at which
depths will be drawn without blue shading.
Chart categories
Several categories and sub-categories are included. You can turn
on/off the categories individually depending on which information
you want to see.
