Visualization & Interpretation JDI software

The first picture below shows the three basic filters (plane, polygon and parameter) while the other picture demonstrates the ability to display a large number of events as pixels (more than 225000).

Jdi also allows filters to be exported to an evp file which is useful when events from other packages have to be displayed.

Once filters have been created, a number of them can be viewed simultaneously. For example, the entire set of events can be shown as pixels to see where the events occurred, the large events can be highlighted by showing them as spheres.

Event Viewing - Filtered events can be displayed using different symbols while sizing and colouring them according to some event parameter. For example, events can be shown as spheres, sized by magnitude and coloured by time. New developments have increased the control over how events are coloured. Users can define their own colour ranges, use Jdi's automatic colouring tool or a single colour.

Jdi has three basic filters (event parameters, plane and polygon) which can be combined using boolean operations (and, or) to create new filters. Using this method some interesting and advanced filters can be created. For example, filter all events for the last two years greater than magnitude 2.0 that do not occur in a set of polygons.

Event Filtering - Different filters can be applied to event sets. For example, filter events in a certain polygon or in a certain magnitude range.

Jdi is ISS International's package for advanced Visualization and analysis in the Microsoft Windows and Linux environment. Jdi was originally developed as a tool to facilitate the integration of modelled and seismic data but has grown to incorporate many features which are more generally applicable.
