SARMetadataCorrection¶
SAR metadata correction.
Description¶
This application corrects metadata with a focus on GCP.
Parameters¶
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).
Examples¶
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")
app.ExecuteAndWriteOutput()
Limitations¶
Only Sentinel 1 (IW and StripMap mode) and Cosmo products are supported for now.
