UNAVCO Short Coarse on StaMPSUtilizing ISCE as InSAR processor
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
