Existing interferometric processing packages are very often difficult to use. This is due to the fact that until recently most of the available software was developed to address specific sensors and processing configurations. This means that the ability to effectively process interferometric data is generally limited to application experts who also have intimate knowledge of SAR sensors. Typically optimal results can only be achieved after multiple runs of the software with different parameter settings. This constraint limits the commercial acceptance of InSAR processing and hinders the development of new applications. To encourage the use of interferometric data sets, PCI Geomatics has developed an InSAR package that can be easily tailored to work in a fully automatic mode. Most of the required settings are automatically derived from the sensor metadata allowing even novice users with little or no formal SAR training to generate excellent results within a very short period of time.

The goal of the workshop is to describe how to effectively use the new Geomatica InSAR module for end-to-end processing, to exploit the full information content that can be extracted from commercially available interferometric SAR data sets. We will demonstrate how to generate both topographic and deformation information products. We will also show how the deformation products can be automatically sorted into coregistered data stacks for rapid visualization and temporal analysis to provide valuable insights into long term subsidence patterns. We will demonstrate how the flexibility of the system significantly reduces the complexity and redundancy of operational InSAR processing.
