When the dataset is selected from the Schedule window in the
explorer, or from one of the menus in the Data Quality Control area, three
workspaces become available. They are accessed by the buttons at the top of the
screen called Quadrapoles, Electrodes and 3D View.
On the electrodes and Quadrapoles screens three menus appear
at the bottom of the workspace. These are IMPORT SYSCAL BIN, REMOVE BAD
DATAPOINTS and SAVE SCHEDULE. The import syscal menu is only active if you go
directly to this screen from the explorer. Rather
than using Input schedule under DATA INPUT of the DI Workspace click
Import Syscal File under The schedule menu on the Explorer. The
remove bad datapoints is for editing data values and is best described in the
quadrapoles description.
The 3D View button presents a workspace that graphically shows the
electrode locations and color coded apparent
resistivity plotted at an appropriate location with respect to the
quadrapole used to collect the datapoint.

Graphical controls using the mouse are as follows: Left click hold and move
rotates the view area. Ctrl (Control) left click and move pans the view. Shift
Right-click hold and move zooms the view area. Double click of any apparent
resistivity colored dot sets the datapoint skip value to 1, i.e.
datapoints selected this way will not be used in the inversion. If you hover
over any apparent resistivity plotted point you get information about that
point. If you hover over an electrode the location of that electrode is
displayed.
Two menus are available:
Rather than using the mouse controls as indicated above
the View aspect may be changed by directly entering values in the thera,
gamma (rotate), thi, and zeta (zoom) controls.
The OW button presents a non-perspective view, the PW button imposes
perspective. The XY, ZY and ZX buttons snap to the planes indicated. The Elec.
switch switchs off the electrodes, the Quad switch switches off the apparent
resistivity presentation, the box switch turns on an outline box, the label
switch turns on XYZ coordinate labels for the extents of the box. The cls
switch turns on a color bar and the extents of the color bar may be
modified using the text entry boxes to the right of the cls switch. The
coloring of the data presentation will change as the color bar extents are
changed.
On the left menu, a list of quadrapoles may be displayed by
checking the Quad. List box. When quadrapoles are selected from the list
the ABMN electrodes are numbered using the
electrode number in the view area.
If one of the X, Y or Z buttons is pushed then a subset of the data from a
plane is displayed. The elevation of the plane is controled used the slider bar
or text entry.
On the screen shown the select button is actually labeled display. Display must
be pushed to calculate the apparent resistivities for display.
