Using ALG graphical user interface

The Atmospheric Look-up table Generator (ALG) software tool facilitates consistent and intuitive user interaction through its Graphical User Interface (GUI), thereby streamlining model setup, running and storing Radiative Transfer Models (RTM) data for any spectral configuration in the optical domain.

In order to start using ALG, just double-click on the ALG icon inside the folder where it was installed (e.g., C:\ALG\bin). This will show the following splash screen:

After a few seconds, the main window of the ALG will appear:

This window is divided into the following elements:

  • A menu bar (top-left) with access to the main functionalities of ALG: Creating a New LUT, Preferences, this Help system and Tools.
  • A set of access buttons (top-left), facilitating a quick access to the main functionalities of ALG.
  • A functionalities sub-panel (right), where the different ALG menus for LUT and software configuration will be displayed.

    In this section...

    • Creating a New LUT: Learn how to create, step-by-step, a new LUT by setting the general LUT options, introducing the key input atmospheric variables, defining the sensor spectral range and resolution and compile/generate a LUT file from RTM output data.
    • Preferences: Configure the ALG software to match your user needs, define new sensors, add new atmospheric RTMs.
