5.1 Data Viewer

The Data viewer page uses a simple Java applet to enable you to check that the DCM is receiving data correctly. Your browser must have Java installed for you to be able to do this.

The data viewer is not intended to be a fully functional data visualisation tool. Scream! and similar software packages offer a full range of facilities for displaying and manipulating seismic data, either as it arrives or from stored data files.

The main part of the display shows a selection of the data streams being recorded, whilst the bars at the top and bottom allow you to control what is displayed, and in what manner:

If you cannot see any data in the Data Viewer, you should check first that

•

•

some streams have been checked in the lower portion of the applet, and

the data has been offset correctly. You can automatically zero the streams by clicking on the icon depicting a “0” and a sine wave in the icon bar. Otherwise, you can zoom out until the streams are visible.
