Overview

To better understand how Calculated Channels work, let’s create one using the temperature Channel from the LEO dataset in Tutorial 1. Specifically, we will create a Calculated Channel that converts the camera_1.temperature Channel from Celsius to Fahrenheit.

​
Create a Calculated Channel

  1. In Sift’s homepage, click the Calculated Channels tab.
  2. Click New Calculated Channel.
  3. In the Calculated Channel name box, enter the following: 
    fl_tutorial_6_calculated_channel
  4. Replace fl (in fl_tutorial_6_calculated_channel) with your initials.
  5. In the Asset list, select the Asset you created in Tutorial 1.
  6. In the Input Channels list, select the following Channel:
    • camera_1.temperature
  7. In the Query (expression) box, enter the following: 
    ($1 * 9/5) + 32
Expressions define how a Calculated Channel derives its values from input data. They can reference input Channels (for example, $1), other Calculated Channels, constants, operators, and built-in functions. Before saving, you can preview the output to verify the expression behaves as expected.
  1. Click the Select Run(s) to preview tile.
  2. In the Runs table, click the name of the Run created in Tutorial 1.
  3. Click Preview 1 Runs.
  4. Click Save.
