Preliminary details

The import process has been validated using a small dataset. For this reason, calibration and interferometry might have issues.

Geocoded SLC data can be visualized and analyzed but SARscape does not yet support interferometric processing chains.

 

Purpose

 

NISAR products, provided in Hierarchical Data, 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. The relevant data type is automatically identified.

 

In case the input is a list of files, all products must be of the same type (refer to the "Supported Products" section).

Input Files

 

Input file list

Input file name(s) of the original data (.h5). These files are mandatory.

 

Output file list

Output file name(s) of the imported data. These files are mandatory.

 

Parameters - Principal Parameters

 

Apply Calibration Constant

The calibration constant is applied (if available). Note: this has no effect of phase values.

 

Fill dummy during import

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

 

Rename Output Using Parameters        

If set to true, only relevant information will be copied from the input name(s) to the output name(s), the full root name otherwise.

 

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

 

Root name of the imported file(s) 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 Units of Measure and Nomenclature of the output products can be found in the Data Format section.

 

General Functions

 

Exec

The processing step is executed.

 

Store Batch        

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

 

Close        

The window will be closed.
