Signal database preparation

Signal viewer for one group of simultaneously recorded waveforms ready for array processing

This step is performed with Geopsy graphical interface. If you have followed all steps for the preparation of a database, loading coordinates and grouping, you should have now a set of simultaneously recorded waveforms building a group and containing coordinates for each waveform.

Alternatively, you can download here a ready-to-go database file and the corresponding waveform files at this location. Note that you have to re-locate your waveform files as described in detail in this page. Or without a graphical interface: 

 $ geopsy-fk -db Lep_ring01_3C.gpy -fix-signal-paths
 ----WARNING--- Opening Database...----
 File '/home/mao/GEOPSY_DOC_WORKSHOP/RING01_SHORT/WA.WAU01..HHE.D.2010.056.000' does not exist.
 The path may have changed. Would you like to manually select its new location?
   1. Yes <-- default

 ---- Opening Database... ----
   Filter: Signal file (WA.WAU01..HHE.D.2010.056.000)
   Current directory: /tmp
   Please select file '/home/mao/GEOPSY_DOC_WORKSHOP/RING01_SHORT/WA.WAU01..HHE.D.2010.056.000' in its new location.
 File to open:

Provide the absolute or the relative path to the requested file(s). For instance: 

 RING01_SHORT/WA.WAU01..HHE.D.2010.056.000

Files having similar paths are automatically translated. At the end the database is saved with your local paths. You can check that all paths are correct by re-starting the same command: you should get not output. You can also view the signals in a graphical user interface: 

 $ geopsy Lep_ring01_3C.gpy


This database contains two predefined groups: vertical and 3C. Please test, whether you can view the signals, use drag and drop functionality or check the coordinate settings in the table view or map view. If you display the predefined group vertical in a graphic viewer, you should obtain a picture similar to the one displayed on the right.

Another way to get the list of groups is: 

 $ geopsy-fk -db Lep_ring01_3C.gpy -groups
 geopsy-fk: Default groups
 geopsy-fk: Default groups/All signals
 geopsy-fk: Default groups/Temporary signals
 geopsy-fk: Default groups/All files
 geopsy-fk: Default groups/Temporary files
 geopsy-fk: Default groups/Permanent files
 geopsy-fk: Default groups/By names
 geopsy-fk: Default groups/By components
 geopsy-fk: Default groups/By receivers
 geopsy-fk: Default groups/By sources
 geopsy-fk: vertical
 geopsy-fk: 3C

Conventional FK

Single component high resolution FK

Three-component high resolution FK (RTBF)

Direct steering three-component high resolution FK
