Purpose

 

Terrain geocoded, radiometrically calibrated and normalized backscattering coefficient data acquired over different satellite orbits are usually mosaiced, making it possible to cover large areas. This functionality can be used also for mosaicing Interferometric products such as Digital Elevation Models and Displacement Maps.

 

Technical Note

 

None.

 

Input Files

 

Input file list

Input file list of the geocoded data (_geo). This file list is mandatory.

 

Parameters - Principal Parameters

 

Interpolation Type

By setting this flag it is possible to specify a spatial region for the Digital Elevation Model extraction (co-ordinates are referred to the output cartographic reference system).

 

In the overlapping areas, pixel values belonging to the last image (with respect to the input file list) are considered as representative.

 

In the overlapping areas, the average of the pixel values are considered as representative.

 

This option is exclusively applicable to mosaic Digital Elevation Model generated with SARscape. In the overlapping areas, the height value is chosen according to the best spatial resolution. The _resolution file is generated during the Digital Elevation Model generation.

 

This option is exclusively applicable to mosaic Digital Elevation Model and Displacement Maps generated with SARscape. In the overlapping areas, the phase value is chosen on the basis of the coherence and baseline. The _precision file is generated during the Digital Elevation Model as well as during the Displacement Maps generation.

In the overlapping areas, a weighted average of the pixel values according to the feathering window is calculated. It is of advantage to set the Feathering Window size to at least the width of the overlapping area.

 

Feathering Window Size

This parameter is activated if Feathering interpolation is chosen. This parameter controls the window size on which a weighted average of the pixel values will be executed.

 

Parameters - Global

 

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

 

Parameters - Other Parameters

Output Files

 

Output file

Output file name of the mosaiced data. This file is mandatory.
