5. How to use the S3-SNOW Processors¶
5.1. Test of the Installation¶
If all plugins described in chapter Software Installation were installed successfully in SNAP, the modules should be visible in their dedicated menus as shown in the figure sequence Figure 5.1 to Figure 5.4.
5.2. Test Products¶
The S3-SNOW project delivery D2.4 ‘Task 2 Data Base’ contains a variety of suitable Sentinel-3 OLCI L1b products which can be used for initial tests of the functionalities of the single processors as well as for the whole processing flow. These products can also be obtained from the S3-SNOW ftp site hosted at BC with the following configuration:
- FTP, Port 21
- ftp.brockmann-consult.de
- username: s3snow
- password: $3Sn0W@bc
- subdirectories: data/<region> (Dome-C, French Alps, Greenland, Morteratsch)
5.3. The SICE Snow Properties Processor¶
5.3.1. GUI Elements¶
When the OLCI SICE Snow Properties Processor is called from its menu entry, the processor GUI is displayed. It contains two tabs ‘I/O Parameters’ and ‘Processing Parameters’, as shown in (Figure 5.5).
5.3.2. Help Documentation¶
From the main menu bar of the processor dialog window, an ‘About’ dialog showing general information on the processor can also be displayed (Figure 5.6).
Also from the main menu bar of the processor dialog window, the SNAP specific help documentation for this processor can be invoked (Figure 5.11, Figure 5.8). This documentation contains some general information, a description of the underlying algorithms (i.e. dedicated references), a description of the processor I/O interface, a description of the processing parameters, and a description how to run the processor from the command line.
5.4. The S3-SNOW Snow Properties Processor¶
5.4.1. GUI Elements¶
When the S3-SNOW Snow Properties Processor is called from its menu entry, the processor GUI is displayed. It contains two tabs ‘I/O Parameters’ and ‘Processing Parameters’, shown for SICE in (Figure 5.9).
5.4.2. Help Documentation¶
From the main menu bar of the processor dialog window, an ‘About’ dialog showing general information on the processor can also be displayed (Figure 5.10).
Also from the main menu bar of the processor dialog window, the SNAP specific help documentation for this processor can be invoked (Figure 5.11, Figure 5.8). This help documentation entry is the same as for the SICE processor.
5.5. The IdePix OLCI Pixel Classification Processor¶
5.5.1. GUI Elements¶
When the IdePix OLCI Pixel Classification is called from its menu entry, the processor GUI is displayed. As all other processors provided for S3-SNOW, it contains two tabs ‘I/O Parameters’ and ‘Processing Parameters’ (Figure 5.12).
5.5.2. Help Documentation¶
From the main menu bar of the processor dialog window, an ‘About’ dialog showing general information on the processor can be displayed (Figure 5.10).
As for all other processors provided for S3-SNOW / SICE, the SNAP specific help documentation for this processor can be invoked from the main menu bar of the processor dialog window. Again, this documentation contains some general information, a description of the underlying algorithms (i.e. dedicated references), a description of the processor I/O interface, a description of the processing parameters, and a description how to run the processor from the command line (Figure 5.14).
5.6. The OLCI O2 Harmonisation Processor¶
5.6.1. GUI Elements¶
When the OLCI O2 Harmonisation is called from its menu entry, the processor GUI is displayed. Again, this processor contains two tabs ‘I/O Parameters’ and ‘Processing Parameters’ (Figure 5.15).
5.6.2. Help Documentation¶
The ‘About’ information and help documentation can be accessed through the ‘Help’ menu in the same way as for all other processors provided for S3-SNOW / SICE.
5.7. The SNAP Slope Processor¶
5.7.1. GUI Elements¶
When the Slope Processor is called from its menu entry, the processor GUI is displayed. Again, this processor contains two tabs ‘I/O Parameters’ and ‘Processing Parameters’ (Figure 5.17).
5.7.2. Help Documentation¶
The ‘About’ information and help documentation can be accessed through the ‘Help’ menu in the same way as for all other processors provided for S3-SNOW / SICE.
