Examples

From the command-line:

otbcli_SAROrthoInterferogram -insarslave s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff -insarmaster s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff -incartmeanmaster CartesianMaster.tiff -topographicphase TopographicPhase.tiff -indem S21E055.hgt -gain 0.1 -out s1b-s1a-s4-Orthointerferogram.tiff

From Python:

import otbApplication

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

app.SetParameterString("insarslave", "s1b-s4-slc-vv-20160929t014610-20160929t014634-002277-003d71-002.tiff")
app.SetParameterString("insarmaster", "s1a-s4-slc-vv-20160818t014650-20160818t014715-012648-013db1-002_SLC.tiff")
app.SetParameterString("incartmeanmaster", "CartesianMaster.tiff")
app.SetParameterString("topographicphase", "TopographicPhase.tiff")
app.SetParameterString("indem", "S21E055.hgt")
app.SetParameterFloat("gain", 0.1)
app.SetParameterString("out", "s1b-s1a-s4-Orthointerferogram.tiff")

app.ExecuteAndWriteOutput()

Limitations

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