Data Range Bitmap

This operator creates a bitmap (Boolean or multibeam Boolean or color Boolean variable) with a true value for each input value that is within a specified range of values, and a false value for each input value that is outside the specified range. "No data" values are always translated to false.

Echoview accepts a single operand of the following data types as input:

Description

Minimum in-range data value

Specify the minimum and maximum data values of the in-range for the bitmap.

When the operand is a color variable, settings can be entered for the Red, Green and Blue components individually.

When the operand is an angular position variable, settings can be entered for the Minor-axis and the Major-axis.

Data values in the operand variable that are within the range are given a value of 'true'.

Data values in the operand variable that are below the minimum data value and above the maximum data value will be given a bitmap value of 'false'.

Maximum in-range data value

Note: No data values in the operand variable will be translated to 'false' for the bitmap.
