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
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
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
Minumum shift on range.
Minumum shift on azimut (output of this application) -minazi float
Default value: 0
Minumum shift on azimut.
Maximum shift on range (output of this application) -maxran float
Default value: 0
Maximum shift on range.
Maximum shift on azimut (output of this application) -maxazi float
Default value: 0
Maximum shift on azimut.
Mean shift on range (output of this application) -meanran float
Default value: 0
Mean shift on range.
Mean shift on azimut (output of this application) -meanazi float
Default value: 0
Mean shift on azimut.
Available RAM (MB) -ram int
Default value: 256
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 (IW and StripMap mode) and Cosmo products are supported for now.
