Opening SAOCOM SLC data in SNAP

Microwave Toolbox
1

Dear SNAP users and developers,

It is possible now to test SAOCOM images in their SLC fomet in SNAP?

Reminder, SAOCOM published detected images . I roughly translated their guide in english here: SAOCOM. how to read in snap.pdf (286.7 KB)

Following the same steps, I was hoping that SNAP could be able to read them, but I have an error saying “unsupported sample format for 64 bits data”.

I imagine it is caused by the complex encoding of the data.

<RasterInfo>
  <FileName>slc-acqId0000089010-a-tna-0000000000-s1qp-hh</FileName>
  <Lines>5256</Lines>
  <Samples>3077</Samples>
  <HeaderOffsetBytes>115770</HeaderOffsetBytes>
  <RowPrefixBytes>0</RowPrefixBytes>
  <ByteOrder>LITTLEENDIAN</ByteOrder>
  <CellType>FLOAT_COMPLEX</CellType>
  <LinesStep unit="s">0.00492178250942089</LinesStep>
  <SamplesStep unit="s">1.666666666666e-08</SamplesStep>
  <LinesStart unit="Utc">04-DEC-2019 10:19:37.199180483818</LinesStart>
  <SamplesStart unit="s">0.004402818811659999811</SamplesStart>
  <InvalidSample/>
  <RasterFormat>DATA_GEOTIFF</RasterFormat>
</RasterInfo>

thanks for reading,
Quentin

I try to visualize the SAOCOM image in SNAP by following tutorial
