Line Range Bitmap

This operator creates a bitmap using the ping geometry of operand 1. Every data point in each output ping will be true if the range (from operand 2) at the time of that ping was within the limits specified, and false otherwise.

Description

Minimum in-range depth (meters)

Specify the minimum and maximum depth for the bitmap.

Data values in the operand variable for which the line is in the specified range (inclusive) are given a value of 'true', and otherwise 'false'. If a line is in the specified range, the ping is included. If the line is not in the specified range, the ping is excluded.
