Geopsy: Signal Viewer
A Signal viewer is a window in Geopsy allowing to view a set or a subset of signals through a table, a graphic , a map or a chronogram . A signal viewer can be created using the View menu and then drag and drop the set of signals of interest in the viewer. Drag and drop signals directly on a signal viewer icon in the toolbar produces the same. When a set or a subset of signals is displayed in a signal viewer (either a table, a graphic, a map or a chronogram) it is possible to perform different actions described hereafter.
Perform basic signal processing
Basic signal processing can be performed on all the signals of the active signal viewer using the menu Waveform.
Perform Advanced Signal processing
Tools are developed as plug-ins and provide specific signal processing. As for basic signal processing, the selected tool is applied to the signals in the active signal viewer. They can be accessed either from Tools menu or from the icons in the toolbar.
All menu items in Edit menu apply to all signals contained in the active signal viewer. In particular the following actions are allowed:
- Editing the metadata in a table
The metadata of signals in the active Table viewer can be modified in the Edit menu. In order to modify metadata It is necessary to unlock the table edition [Ctrl+K]

- Set headers, apply formula to a column
Set headers for a Table viewer allow to modify the header information by means of generic formulas.
- Set receivers
