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. Assuming unwrapping is done based on raster data (as opposed to point data, as is the case for PSI), the following workflow is proposed:1. Import unwrapped phase or deformation data as generated by external software package (e.g., SNAPHU).2. Geocode both ascending and descending unwrapped datasets.3. Align both datasets by interpolating them to a common grid.4. Convert to horizontal/vertical[R-11]. Recommendations:1. It is assumed that the enhancement as described for S1TBX-SE-2 has been used for exporting2. SNAP/S1TBX is not optimized for processing/visualization of vector data (point data in this case). If line-of-sight deformation time series have been generated by external software packages (e.g., StaMPS), the resulting dataset may be a set of points – not necessarily raster data. In these cases, it is recommended for users to implement the functionality described in this enhancement outside of SNAP/S1TBX.
