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.
