SAR metadata correction.


This application corrects metadata with a focus on GCP.


Input DEM -indem image Mandatory
Input DEM to extract height data.

Input SAR image -insar image Mandatory
SAR Image to extract initial metadata.

Input file to get precise orbits -infineorbits filename [dtype]
Input file to get precise orbits.

Parameters estimation modes -mode [auto|gcp|orbits] Default value: auto

  • User Defined
    This mode allows you to fully modify default values : GCP corrections
  • GCP corrections
    This mode allows you to automatically correct GCP into the output geom file
  • Fine orbits
    This mode allows you to automatically retrieve the fine orbits and to save into a new geom file

Write the OSSIM keywordlist to a geom file -outkwl filename [dtype]
This option allows extracting the OSSIM keywordlist of the image into a geom file.

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


From the command-line:

otbcli_SARMetadataCorrection -indem S21E055.hgt -insar s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff

From Python:

import otbApplication

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

app.SetParameterString("indem", "S21E055.hgt")
app.SetParameterString("insar", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff")



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