SARConcatenateBursts¶
Concatenate a list of Bursts to provide a whole SAR Deburst Image.
Description¶
This application performs a burst concatenation and provides a SAR Deburst Image. It reads the input image list (single bursts) and generates a whole SAR image with deburst operations.
This application has several output images and supports “multi-writing”. Instead of computing and writing each image independently, the streamed image blocks are written in a synchronous way for each output. The output images will be computed strip by strip, using the available RAM to compute the strip size, and a user defined streaming mode can be specified using the streaming extended filenames (type, mode and value). Note that multi-writing can be disabled using the multi-write extended filename option: &multiwrite=false, in this case the output images will be written one by one. Note that multi-writing is not supported for MPI writers.
Parameters¶
Input bursts list -il image1 image2... Mandatory
The list of bursts to concatenate.
Input Sentinel1 IW SLC Image (only metadata used) -insar image Mandatory
Raw Sentinel1 IW SLC image, or any extract of such made by OTB (geom file needed).
Output Image -out image [dtype] Mandatory
The concatenated and debursted output image.
Index of the first Burst -burstindex int Default value: 0
Index for the first required Burst
Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).
Examples¶
From the command-line:
otbcli_SARConcatenateBursts -insar s1_iw_slc.tif -il Burst0.png Burst1.png -out otbConcatenateBursts.tif
From Python:
import otbApplication
app = otbApplication.Registry.CreateApplication("SARConcatenateBursts")
app.SetParameterString("insar", "s1_iw_slc.tif")
app.SetParameterStringList("il", ['Burst0.png', 'Burst1.png'])
app.SetParameterString("out", "otbConcatenateBursts.tif")
app.ExecuteAndWriteOutput()
Limitations¶
Only Sentinel1 IW SLC products are supported for now. In order to concatenate several bursts, all valid lines of each burst are required as inputs.ie : Careful with ROI extraction inside a Burst.
