Grid Size – Press the + and - buttons to cycle between pre-set sizes. These are all
square grids. If the grid size becomes too large, it cannot be processed on the DVL, and
it will display a message in red beside the Depth Slices field saying "EKKO_Project
Only". This means that, based on the size of the grid, it cannot be processed into depth
slices on the DVL; the grid must be exported from the DVL and processed in the
EKKO_Project PC software.
Line Spacing – Press the + and - buttons to vary the spacing between adjacent lines.
Note: Target size determines line spacing. In most cases the system must pass over
a target to detect it; line spacing needs to be on the order of the size of the target or
smaller when practical. Line spacing can be further apart for larger targets or targets
with a linear extent. These rules may have to be relaxed for practical purposes such
as survey production rates. Tighter line spacing takes longer to collect and may not
be economically possible in all circumstances.
Line Pattern - Grid lines can be collected in one direction (Forward) or in a back and
forth pattern (Alternating) (Figure 7-30). Collect lines in forward mode when possible to
reduce errors due to a poor odometer calibration. Press the Line Pattern button to
toggle between modes.
