SARTopographicPhase

Estimates topographic phase for interferogram.

Description

This application estimates the topographic phase between two SAR images in order to improve the interferogram.

Parameters

Input deformation grid -ingrid image Mandatory
Input deformation grid.

Input SAR Slave image (metadata) -insarslave image Mandatory
Input SAR Slave image (metadata).

Input Cartesian Mean Master image -incartmeanmaster image Mandatory
Input Cartesian Mean Master image.

Grid Step for range dimension into SLC geometry -gridsteprange int Default value: 150
Grid Step for range dimension into SLC geometry.

Grid Step for azimut dimension into SLC geometry -gridstepazimut int Default value: 150
Grid Step for azimut dimension into SLC geometry.

ML factor on range -mlran int Default value: 3
ML factor on range.

ML factor on azimut -mlazi int Default value: 3
ML factor on azimut.

Copy cartesian coordonates into output -cartcopy bool Default value: false
If true, Copy cartesian coordonates into output.

Topographic Phase (And Copy of Cartesian Mean Master Image) -out image [dtype] Mandatory
Output Image : Topographic Phase (And Copy of Cartesian Mean Master Image).

Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).

Examples

From the command-line:

otbcli_SARTopographicPhase -insarslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -incartmeanmaster CartesianMaster.tiff -ingrid ./FineDeformation.tiff -out topographicPhase.tiff

From Python:

import otbApplication

app = otbApplication.Registry.CreateApplication("SARTopographicPhase")

app.SetParameterString("insarslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff")
app.SetParameterString("incartmeanmaster", "CartesianMaster.tiff")
app.SetParameterString("ingrid", "./FineDeformation.tiff")
app.SetParameterString("out", "topographicPhase.tiff")

app.ExecuteAndWriteOutput()

Limitations

Only Sentinel 1 (IW and StripMap mode) and Cosmo products are supported for now.
