Purpose

 

This panel is used to project the three displacement components (East, North and Vertical) into the Line-of-Sight.

An example involving this panel can be found in the tutorial.

 

Technical Note

 

After Forward Modeling, the three images with the East, North and Up components can be combined to calculate the displacement in the Line-of-Sight. This is carried out by supplying the _ALOS and _ILOS raster images produced with the interferometric processing. Extent and resolution of the output raster can be set through pull down menus; two alternatives are provided: equal to that of the East/North/Up images or equal to that of the ALOS/ILOS images.

In addiction, to create a perfect matching with a real InSAR displacement map, it is possible to add an orbital contribution; the easier way is to retrieve the orbital contribution through the 'Get from XML...' button, that explore an XML project file (orbital parameters are generally present as result of a Non-Linear or Linear inversion)

Optionally, it can be generated also a wrapped raster map, using X, C and L band with predefined fringe rate or manually setting an arbitrary interval.

 

Input Files

 

East component

Image with the East component of the displacement. This file is mandatory.

 

North component

Image with the North component of the displacement. This file is mandatory.

 

Up component

Image with the Up component of the displacement. This file is mandatory.

 

Azimuth LOS image

ALOS images from an interferometric processing.

 

Incidence LOS image

ILOS images from an interferometric processing.

 

Parameters - Principal Parameters

Raster extent

Extent of the output image in meters.

 

Raster resolution

Resolution of the output image in meters.

 

Add/Edit orbital surface...

Add an orbital contribution (offset, ramp or quadratic surface); typically, orbital parameters come from an inversion and are retrieved with 'Get from XML project file...'.

 

Output wrapped fringes

Create also a wrapped version of the LOS displacement map. The fringe ambiguity can be set from a list or manually.

 

 

Output Files

 

Output image

Image with the displacement projected into the Line-of-Sight. If the 'Output wrapped fringes' flag is set, a wrapped version with the suffix '_wrapped' is also generated
