Figure 2-12-3 True or false depth judging
The red line is simulative echo signals, and the blue one is the digital water depth point. If these
two match, the water depth is true and accurate. Then conduct the filtering. Hi-Max software
provides three filtering methods. Users can choose anyone up to their needs. Experience tells us
that the
Filter Level
is generally set below “3”. Then click
Process
to finish this step. After
filtering, most of the fake water depth has been processed, and then drag the progress bar below
the wave display window to check the place where the blue line does not match the red line. If
there is no match, users need to hold down and drag the blue line with the left mouse button to
match the red one manually.
The next step is a sampling. There are two sampling methods for users to choose in
Sampling
Settings
. If users choose the model, just enter a proper interval according to needs and then click
Sampling
to complete it. If there is a feature point between two sampling points that need to be
extracted, click the
Sampling
on the menu bar; Users can use the mouse to extract this point
manually.
