General Description 

Xdi is the primary ISS visualization and interpretation software package. The seismic data that is visualized and interpreted consists of the event parameters extracted from seismograms using amts or xmts (seismological processing software). Seismic events are displayed on a three-dimensional map with symbol sizes and colours adding information. Xdi has the option to connect to the RTS (runtime system), where events are displayed live as they are collected by the system. Various routine reports can easily be generated using Xdi.



Visualization & Interpretation


 

Visualization: Various parameters (like radiated seismic energy, seismic moment, magnitude, event time etc.) are represented by symbol type, size and colour. Seismic events can be filtered by time period, ranges of seismic parameter values and spatially by filtering on polygons, mine boundaries, sites etc. Settings are saved to file and can be accessed by selecting a project.

Interpretation: Contouring is possible for various parameters describing a seismic event. In this way regions of high seismic stress, etc. can easily be identified. Size Distributions indicate the mean recurrence times of seismic events above certain magnitudes, seismic network sensitivities, etc. and plot the results in concise graphical formats. Empirical Probabilities that an event of a certain magnitude will occur within a certain time period based on collected seismic data can be calculated. Time History plots display the time behavior of seismicity in given polygons and have proved very useful in trend detection and indicating areas of potential instability.

 


 


 


Reporting:
Reporting functions enable the user to pre-define routine report formats and automatically generate HTML reports. The text and graphical reports that are generated can be viewed and printed from Linux, Microsoft Windows or IRIX computers using an HTML browser (e.g. Netscape or Internet Explorer). Reports can be displayed on the Intranet, allowing the user who has access to view any report at any time on his desktop PC. When a report is created, a corresponding pdf file is also created. This file can be e-mailed and contains the graphical information pertaining to the report. Each HTML report also has a link to the pdf report.


 

Run Time System (RTS):   Xdi is highly integrated with the ISS system. It can be used to set up and control certain aspects of the RTS and system specific parameters, and it gives direct access to the ISS database.
