Time: the software takes a depth value at the set interval (time), and
estimates the coordinates of the sampling point based on the marking
coordinates of the two adjacent points.

Distance: the software takes a depth value at the set interval (distance),
and estimates the coordinates of the sampling point based on the
marking coordinates of the two adjacent points.

Mark: the software takes a depth value at the set interval (marking),
eliminates the depth of the middle point, and rarefies the depth data.
Note: The minimum interval for sampling by time and distance is
0.05 , and for sampling by marking is 1 .
