+# SARGridStatistics
+
+Computes grid statistics.
+
+## Description
+
+This application computes some statistics for a deformation grid such as minimum, maximum shift or mean shift on each dimension.
+
+## Parameters
+
+**Input grid (Vector Image)** `-ingrid image` *Mandatory* <br />
+Input Grid Vector Image (Shift_ran, Shift_azi).
+
+**Threshold for computation of mean shift (used only if grid components are superior or equal to 3)** `-threshold float` *Default value: 0.3* <br />
+Threshold for computation of mean shift (used only if grid components are superior or equal to 3).
+
+**Minumum shift on range (output of this application)** `-minran float` *Default value: 0* <br />
+Minumum shift on range.
+
+**Minumum shift on azimut (output of this application)** `-minazi float` *Default value: 0* <br />
+Minumum shift on azimut.
+
+**Maximum shift on range (output of this application)** `-maxran float` *Default value: 0* <br />
+Maximum shift on range.
+
+**Maximum shift on azimut (output of this application)** `-maxazi float` *Default value: 0* <br />
+Maximum shift on azimut.
+
+**Mean shift on range (output of this application)** `-meanran float` *Default value: 0* <br />
+Mean shift on range.
+
+**Mean shift on azimut (output of this application)** `-meanazi float` *Default value: 0* <br />
+Mean shift on azimut.
+
+**Available RAM (MB)** `-ram int` *Default value: 256* <br />
+Available memory for processing (in MB).
+
+## Examples
+
+From the command-line:
+
+```
+otbcli_SARGridStatistics -ingrid ./grid.tiff
+```
+
+From Python:
+
+```
+import otbApplication
+
+app = otbApplication.Registry.CreateApplication("SARGridStatistics")
+
+app.SetParameterString("ingrid", "./grid.tiff")
+
+app.ExecuteAndWriteOutput()
+```
+
+## Limitations
+
+Only Sentinel 1 products are supported for now.
