The Geophysical TimeLine Demo is a working version of the actual Geophysical TimeLine itself.

Tto run the demo, select a location from the drop down box in the Location panel to propagate the search criteria for this area.  Then select one or more data sources from the Data Source list panel.  Setting a specified time to further narrow down the query is optional from the Time panel.  The Result Options panel offers different ways of viewing the query results.  For maximum return to the query, leave these options at their default values.  Once all of these settings have been set, press the Execute Query button (red arrow button) from the task bar, or select the Execute Query button from the menu bar under the Tools menu.

What will be displayed is a TimeLine of the data resulting from the query.  On the left side will be a tree of data sources from which each file belongs.  On the right is the TimeLine itself with an image representing each file.

If any of the images is double clicked, a visualization window will be created to display the image data.  Depending on the display mode selected, the data in the visualization may be manipulated in various ways.

To use the text interface for our query language, isOQL, go to Tools-> Text Interface. A sample query you can execute with the data onhand is:

DEFINE EXTENT Frames for EOSSchema.EOSFrame;
DEFINE EXTENT Stacks for EOSSchema.Stack;
SELECT F FROM STREAM_BT[NOW - 1 YEAR] AS F;

Feel free to explore the various features of the TimeLine such as the spawning visualization and timeline windows, tool tip metadata, or zoom in and zoom out capabilities.  Note however that several features are not available yet for the demo.  These include, save and open commands as well as tools such as outline and the ruler.  Also note that several features may contain minor bugs given that the application is still in a prototype phase.
