+# SARGridOffset
+
+Applies offsets on a deformation grid.
+
+## Description
+
+This application applies offsets on a deformation grid for each dimension.
+
+## Parameters
+
+**Input grid (Vector Image)** `-ingrid image` *Mandatory* <br />
+Input Grid Vector Image (Shift_ran, Shift_azi).
+
+**Offset on distance** `-offsetran float` *Default value: 0* <br />
+Offset on distance
+
+**Offset on azimut** `-offsetazi float` *Default value: 0* <br />
+Offset on azimut
+
+**Output Grid** `-out image [dtype]` *Mandatory* <br />
+Output Grid.
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+Available memory for processing (in MB).
+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARGridOffset -ingrid ./grid.tiff -offsetran -0.1 -offsetazi 0.1 -out correctionGrid.tif
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARGridOffset")
+
+app.SetParameterString("ingrid", "./grid.tiff")
+app.SetParameterFloat("offsetran", -0.1)
+app.SetParameterFloat("offsetazi", 0.1)
+app.SetParameterString("out", "correctionGrid.tif")
+
+app.ExecuteAndWriteOutput()
+```
+
+## Limitations
+
+Only Sentinel 1 products are supported for now.
