| OWT Classification - Processor Description | ![]() |
The OWT Classification processor can be invoked from the VISAT tool menu by selecting
the MERIS OWT Classification command from the Processing / Thematic Water Processing menu. On the command line the OWT Classification processor is
available by means of the Graph Processing Tool gpt which is located in the BEAM bin
directory. Typing gpt OWTClassification -h displays further information.

Source product: Here the user specifies the source product. The combo box presents a list of all products opened in the VISAT. The user may select one of these or, by clicking on the button next to the combo box, choose a product from the file system.
