Preliminary details

The import process has been validated using a small dataset. For this reason, radiometric calibration and absolute geolocation have issues.

Purpose

 

Standard products, acquired by the Fucheng-1 missions, are imported into the SARscape Data Format for further processing.

 

Technical Note

 

The import functionality requires only the input Parameter file(s) to be entered. In case the input is a list of files, all products must be of the same type (refer to the "Supported Products" section).

The User should also make sure the appropriate SARscape Preferences are loaded (see the “Preferences” section below).

 

 

Supported Products

 

 

Input Files

 

Input Parameters File list

Input file name(s) of the original Parameter file(s) (manifest.safe). These files are mandatory.

Tip: In order to import a large amount of acquisition, we suggest to use the "Open Folder" or "Select File List" function.

 

Parameters - Principal Parameters

 

Polarization

This option let to choose which polarization should be imported in case the original data contains more than 1 polarization. Options are: All, Copolarization (VV or HH) and Crosspolarization (VH or HV). This is helpful in case of only one polarization is needed (e.g. only copolarization for interferometry purposes) reducing the time of the import and the space on disk needed.

 

Fill dummy during import

Possibility to replace invalid backscatter pixel values with random low values.

 

Rename Output Using Parameters

If this option is not set, the output files will be placed in the output directory with the root name which appears in the Output File List.

If this option is set (recommended), the output files will be placed in the output directory with an automatically generated root name, assigned based on the input file parameters.

 

Note: the Data Type is automatically detected and selected.

 

Parameters - Global

 

It brings to the general section of the Preferences specific parameters. Any modified value will be used and stored for further processing sessions.

 

Parameters - Other Parameters

 

It brings to the general section of the Preferences parameters. Any modified value will be used and stored for further processing sessions.

 

Output Files

 

Output file list

Output file name(s) of the imported data.

Each entry specifies the output path (output directory and root name) of the imported file and associated header files (.sml, .hdr). The output directory can be changed selecting Change Output Directories in the menu. Click on the folder icon to browse to the output directory and then click on the green tick mark to apply the change.

These files are mandatory.

 

Root name of the imported file and associated header files (.sml, .hdr). Specific file suffixes are added according to the data type.

 

.shp

Shape file and associated header files (.sml, .hdr) containing the image perimeter in geographic co-ordinates.

 

.kml

ASCII file containing the image perimeter in geographic co-ordinates. Double clicking on this file will automatically position the boundaries of the scene into the Google Earth environment.

 

Details specific to the measurement units and naming of the output products can be found in the Data Format section.
