S1TBX-SE-11 Retrieval of Vertical and E-W motion components from a pair of interferograms

Description

This enhancement would allow for converting from ascending/descending line-of-sight deformation components to horizontal (East-West) and vertical components. The following workflow is proposed:

  1. Coregister an ASC and a DSC stack. We’ll support two-image stacks (i.e., a single slave).

  2. Form ASC and DSC (DEM flattened) interferograms and multilook.

  3. Unwrap using SNAPHU.

  4. Apply Terrain Correction and Collocation operators to geocode and align the (unwrapped) ASC and DSC interferograms.

  5. Call new operator to convert to horizontal/vertical motion.

Tasks:

  • (Done) Design workflow.

  • (Done) Develop operator for computation of horizontal/vertical motion. Note: we need to update the Collocation operator to make sure the orbit heading is not lost.

  • (Done) Add HTML docs.

  • (Done) Validate with real data.

  • (Done) Add tests.

this feature is now on the master branch. We’ve also added integration tests to . I’ll mark this as resolved.
