Sensor configuration

The Sensor configuration allows users to modify the spectral configuration (i.e., spectral range and resolution) of a set of pre-defined sensors stored in the Sensorconf.xml file in the ALG Conf folder.

The user can select the sensor by the in the top-left pop-up menu. The selected sensor can be multiband or hyperspectral. The difference between them resides in that:

  • A multiband sensor (e.g., OLCI/Sentinel-3) has pre-defined spectral channel with their corresponding barycenter and spectral resolution (FWHM).

  • A hypespectral sensor (e.g., FLORIS/FLEX) has pre-defined spectral bands defined by their minimum/maximum wavelengths, spectral resolution (FWHM) and spectral sampling interval (SSI).

Accordingly, the user can modify the spectral configuration of a sensor by modifying its parameter values (i.e., barycenter, FWHM, min/max wavelength or SSI) or by removing the selected () spectral channels/bands from a sensor, pressing the button at the bottom-right corner. In addition, users can add new bands by pressing the button.

The user can add new sensor into the Sensorconf.xml file by selecting the Add new sensor on the Select sensor pop-up menu. In this case, the user should select the sensor spectral mode (multiband or hyperspectral) and fill the values on the table.

The user can also remove a sensor from the Sensorconf.xml file by selecting it from the Select sensor pop-up menu and pressing the Remove sensor button. A warning dialogue window will appear to confirm the removal of the selected sensor.

To apply the changes, click on the Apply or Apply and Close buttons. This will update the Sensor configuration file (Sensorconf.xml) stored in the ALG Conf subfolder. Notice that these changes cannot be undone.
