About line status
Echoview assigns the following line status to line segments in a line:
- good (displayed in green)
- bad (displayed in magenta)
- unverified or uncertain (displayed in cyan)
- none (not displayed - undefined line position)
A line status of good or bad is automatically assigned to line data when lines are created by line picking. Lines are drawn in line status colors with a line thickness. Line status colors and thickness may be specified for all lines in an EV file or for a particular line variable.
To manually assign line status:
- Make a line active by selecting it from the Line and Surface tool list
. - Select the section of the line to which you are assigning a line status, using one of the selection tools.
- On the Shortcut menu (right-click), point to Set Line Status and then click the required line status
Notes:
- When you assign line status manually, new interpolated coordinate points are created.
- If you choose None, the section of the line will be deleted.
- User-defined keyboard shortcuts are available for each type of line status.
Line status has the following uses:
- as a quality control tool for bathymetric applications.
- only pings with a good exclude-below line status are used to calculate the mean line depth (Exclude_below_line_depth_mean) and mean line range (Exclude_below_line_range_mean).
- pings with a bad exclude-below line status can optionally be excluded from analyses (on the Analysis page of the Variable Properties dialog box).
- the exclude-below line status of a ping, is the status of the chosen exclude-below line at the time of the ping.
