School of Earth and Environment ISCE as InSAR processor for StaMPS

Utilize ISCE as a modular Library (Zero-Doppler module)

§ Support for both native and zero-Dopplerü No need to force zero-doppler!

§ Geometry mapping based on orbitsü Orbits are accurate!

§ Fine coregistration (uniform sub-pixel offset)ü Uniform offset is more robust to estimate

§ Resampling§ Interferogram formation

ü No filtering and multi-looking

§ In future:o Cascade coregistrationo Update towards IsceApp.pyo Include TopsApp.py support
