GAMMA output ——Miaplpy input #142

Description

@chdHWang

Describe the bug
When importing coregistered burst SLC data processed by GAMMA via miaplpyAPP miaplpyAPP.cfg --dostep load_data, the slcStack.h5 file is generated successfully with correct dimensions. However, the program throws a dimension broadcast error while creating geometryRadar.h5, failing to generate geometry files for subsequent InSAR processing.
The core error is ValueError: operands could not be broadcast together with shapes (2720,2699) (2720,10797) during incidence angle calculation.
My Operation Workflow

  1. Process Sentinel-1 burst SLC data and complete coregistration using GAMMA software;
  2. Prepare geometry input files for Miaplpy: Directly rename the GAMMA-generated lookup table file to*.utc_to_rdc (I am not sure if this operation is correct, which is the core confusion point);
  3. Execute data loading step: miaplpyAPP miaplpyAPP.cfg --dostep load_data;
  4. The slcStack.h5 file is written normally, but geometryRadar.h5 generation fails with dimension mismatch error.
    Key Questions & Confusion
  5. File usage correctness: Is it correct to directly rename GAMMA-generated lookup table file to *.utc_to_rdc for Miaplpy geometry input?
  6. Dimension mismatch root cause: The slcStack.h5 dimension is fixed as (45, 2692, 2720), but the incidence angle calculation shows abnormal dimensions (2720,2699) and (2720,10797). Is this caused by incorrect lookup table/DEM file?
  7. GAMMA file import specification: Is there an official sample file and detailed specification for importing GAMMA-processed burst SLC data into Miaplpy? Including standard naming rules and file preparation steps for geometry files (utc_to_rdc, rdc.dem, etc.).
