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.
