You can run the InSAR algorithms separately or sequentially. Supported data is single-look, slant-range data acquired in strip-map mode from single-pol and multi-pol configurations.
Important: The phase-unwrapping software used with INSUNWRAP, SNAPHU, is limited to a maximum file size of approximatlely 23,000 pixels by 23,000 lines (512 megabytes) per channel.
The processing sequence of running InSAR algorithms can be summarized as follows:
- Creation of interferograms
- Ingest SAR data to extract metadata and geocoding information
- Coregister images (automated)
- Create raw or filtered interferogram
- Create interferometric products
- Remove flat-Earth and topographic effects
- Remove residual-orbital errors
- Unwrap the interferometric phase
- Adjust output products
- Convert to orthorectified final product
- Temporal analysis of surface subsidence
- Extract temporal parameters from unwrapped interferometric stacks
- Visualize enhanced temporal information
