Snaphu Data Export

Exporting data for SNAPHU processing

SNAPHU Data Export 

The main purpose of SNAPHU data export functionality is three-fold:

1. To export data (bands) in the format compatible for SNAPHU processing,
2. To build a SNAPHU configuration file (snaphu.conf), the file where processing parameters for SNAPHU are being stored,
3. To construct a container product that will store metadata and bands to be used when SNAPHU results are being ingested back into the Toolbox.

External processing with SNAPHU

Given that the SNAPHU software is properly installed and configured, unwrapping of exported product is quite straightforward. In the directory where the SNAPHU product is being saved, the following command is to be executed:

snaphu -f snaphu.conf YOUR_PHASE_BAND.img 99999

where YOUR_PHASE_BAND.img stands for the name of the phase band that is to be unwrapped, and 99999 represents the number of lines of the YOUR_PHASE_BAND. Note that the command to be externally called for the phase unwrapping is listed in the header of snaphu.conf file that is created with the SNAPHU writer.

Again, it is strongly recommended that before doing any processing with SNAPHU user becomes familiar with the software and process control flags.
