4.4.5. Use Depths
Depth Palette
Intensity Palette
When
Use Depths
is enabled the
the
Depth Palette
is used to show
different depths in different colours. The
start and end depth of the palette can
be entered (in metres or feet, depending
on the unit type selected). All depths
shallower than the top depth use the first
colour of the palette and depths deeper
than the bottom depth will use the last
colour of the palette. The bottom depth of
the palette also sets the bottom depth of
the 3D grid.
When
Use Depths
is not enabled
the
Intensity Palette
is used to
colour points for 0-100% of intensity.
The
Intensity Palette
is also used
for the Forward Looking (2D) display.
4.4.6. Draw Points
Normally data is shown as a series of scan images with data being faded based upon
the intensity of the target. Targets with intensity below 5% are not displayed and
those above 5% are semi-transparent becoming more opaque as the targets become
brighter.
With
Draw Points
enabled, data is instead drawn as a points cloud, which allows
accurate measurements to be made between points. Only sonar contacts with an
intensity above a set threshold are considered to be a point (the
Threshold
is set
in the Advanced Options - see Section 4.7.2, “Sonar”).
