Distance: This is the distance between the end-points of the
rubber-band line drawn from one contact to another.
Pixel: This displays the x (x-axis coordinate), y (y-axis
coordinate), and z data (intensity) of any pixel in the displayed
image.

Latitude: Degrees north or south of the equator. This changes
to Northings if the data were recorded that way
Longitude: Degrees east or west of the meridian. This changes
to Eastings if the data were recorded that way.
Range: This is the range from the towfish to the current point,
either the cursor or the object being measured.
Width: Across-track distance of mensuration.
Length: Along-track distance of mensuration.
Height: Height is how far an object stands above the seabed.
Height computation uses the length (width in across-track) of
the shadow, distance of the object from the towfish, and the
towfish altitude.
Depth: This is the vertical distance the target is from the sea
surface.
Pings: Number of pings traversed by a drawn line. Also see
‘Number of Pings’.
Beam W.: Width of the beam at a specific range distance. This
parameter is updated with any length measurements. Also see
‘Beam Width’.

L.Rot. (Length Rotation) Rotation angle of the length line
relative to a horizontal line. Angle is computed from a
horizontal line. Also see ‘Length Rotation’ on page 28.
L.Adj. (Length Adjust) is the difference between the length of a
line and its along-track length. In the case of a slanted line,
length is derived from the vertical component of the line, and
the L.Adj. measures the difference between the length of the
line and the along-track length. Also see ‘Length Adjust’.
W.Adj. (Width Adjust) is the difference between the length of
the line and the across-track width. Also see ‘Width Adjust’.
W.Rot. (Width Rotation) Rotation angle of the width line
relative to a horizontal line.
