+# SARESD
+
+ESD processing to correct phase between two bursts.
+
+## Description
+
+This application applies esd processing on two consecutives bursts dimension.
+
+## Parameters
+
+**First interferogram (Vector Image)** `-ininterfup image` *Mandatory* <br />
+First interferogram.
+
+**Second interferogram (Vector Image)** `-ininterflow image` *Mandatory* <br />
+Second interferogram.
+
+**Input SAR  image (for metadata only** `-insar image` *Mandatory* <br />
+SAR Image to extract SAR geometry.
+
+**Index of first interferogram** `-burstindex int` *Default value: 0* <br />
+Index of first interferogram.
+
+**Threshold for correlation rate** `-threshold float` *Default value: 0.3* <br />
+Threshold for correlation rate.
+
+**Averaging on azimut** `-mlazi int` *Default value: 1* <br />
+Averaging on azimut
+
+**Output Tmp** `-out image [dtype]` *Mandatory* <br />
+Output Tmp.
+
+**Azimut shift to correct phase jump into two consecutive interferograms** `-azishift float` *Default value: 0* <br />
+Azimut shift to correct phase jump.
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+Available memory for processing (in MB).
+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARESD -ininterfup ./interferogram_burst0.tiff -ininterflow ./interferogram_burst1.tiff -insar s1a-iw1-slc-vv-20150821t152433-20150821t152458-007363-00a1e0-004.tiff -burstindex 0 -out phaseDiff.tif
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARESD")
+
+app.SetParameterString("ininterfup", "./interferogram_burst0.tiff")
+app.SetParameterString("ininterflow", "./interferogram_burst1.tiff")
+app.SetParameterString("insar", "s1a-iw1-slc-vv-20150821t152433-20150821t152458-007363-00a1e0-004.tiff")
+app.SetParameterInt("burstindex", 0)
+app.SetParameterString("out", "phaseDiff.tif")
+
+app.ExecuteAndWriteOutput()
+```
