The following indications are intended to simplify the procedure of filling the different processing panels with the appropriate information (i.e. files and parameters).

 

This page must be intended as a general description, which is applicable to all processing panels. Nevertheless some interfaces may require more detailed information about specific files, parameters or settings, which are not considered in the present description; these peculiarities are eventually reported in the relevant section of this guide.

 

 

Input Files

This tab allows the definition of all mandatory inputs and, in particular cases (e.g. the SRTM DEM extraction), also some optional files. The right mouse button enables the following actions:

•Add - to insert a new input file. The same action can be performed with the "Browse" button.

•Add List - to insert a new input file list. It allows pasting list of files from the selected path. The same action can be performed with the "Browse" button.

•Add Folder - to add all the relevant files present in a root folder (e.g. to insert all the manifest.safe in the input file list during Sentinel-1 import).

•Remove - to erase an input file.

•Edit - to modify the name and the path of an input file.

 

Please note: that Drag & Drop option is allowed. The graphical user interface is available to select a file or multiple files and move them to Input Files location and "drop" it there.

 

Optional Files

This tab allows the definition of the inputs which are not mandatory to execute the process. The optional files are required only in some special cases. Usually, the process is executed at first without the use of the optional files and, if the results are not satisfactory, the process is re-executed with their inclusion to improve the results. This is for instance the case of the Coregistration file, which can be adopted to solve some coregistration related failures; or the GCP file, which can be adopted to correct the orbital parameters when they are not sufficiently accurate to achieve an accurate image geo-location.

 

DEM/Cartographic System

This tab allows either the definition of the output cartographic reference system or entering the reference Digital Elevation

, which will be considered in processes such as the Geocoding, the Interferogram Generation, the InSAR DEM Workflow and others. It is worth to mention that, selecting this tab, one has the possibility to either input an existing DEM or extract a new one by means of the dedicated tool.  

 

Output Files

The name and location for the output files is defined. The right mouse button enables the following actions:

•Edit - to modify the name and the path of an output file.

•Remove - to erase an output file. The corresponding input is automatically cancelled.

•Add List - to insert a new output file list. It allows pasting list of files from the selected path. The same action can be performed with the "Browse" button.

•Change Output Directories - to modify the name of the destination folder for all output files.

•Change Output File Extensions - to modify the extensions (i.e. file name suffix) for all output files.

 

Parameters

The interface is structured in order to allow either an easy use (for beginners) or a full interaction with all processing parameters (for advanced users). Two ways are provided to define the processing parameters:

1.Selecting the "Principal Parameters" from the pull down menu, the most important (and easier to understand) values are visualized with the possibility to modify them. Once this has been done the processing step can be executed without changing any of the additional parameters, which are listed in the pull down menu (e.g. "Coregistration", "Filtering", "Flattening", "Others", etc.). Any parameter, which is not specifically set by the user, is automatically retrieved by the program from the currently active Preferences. This is the suggested approach for beginners.

2.Beneath the "Principal Parameters" button, in the pull down menu, there are several groups of advanced parameters, which can be loaded and modified by choice (e.g. coregistration, filtering, flattening, others, etc.). The name of each group is based on the parameters which are contained. Experienced users, who already have a good knowledge of SARscape, often prefer to check and possibly tune all available parameters; this is important in order to exploit the characteristics of the software at their best and also to customize the processing depending on the peculiarities of the input data.

 

It is worth to mention that the original parameters, which are shown within each interface once it is opened, are the same as those written in the currently active Preferences. If one or more parameters are modified in any specific processing interface, these new values are adopted for the subsequent processing, while the values written in the currently active Preferences remain unchanged. In other words, the Preferences are not affected by changes applied on the processing interfaces.

 

In some cases (e.g. General Tools > Geoid Component) the processing can be executed only once the required parameter setting has been selected (i.e. "Geoid Operation").

 

It happens that some portions of the panel appear in light grey (i.e. not editable fields). This is because, in certain processing configurations, those fields must not be considered. This is for instance the case of the "Output Projection", which cannot be specified if a DEM is entered as input; indeed the output cartographic reference system will be the same as the input DEM.  

 

Store Batch

The processing step is stored in the batch list. The Batch Browser button allows to load the processing list.

 

Exec

The processing step is executed.

 

Close

The processing panel is closed.
