Bands
14-29
Drag the cursor around the perimeter of the region you want to define as a
band. A line will appear, defining the boundary.
Fig. 14-20. Draw Band Boundary tool.
If you make a mistake and need to retrace part of the band boundary, simply
backtrack with the cursor; the previous path will be erased and you can
redraw it.
Note: It is important to magnify the image before drawing a boundary. If you
try to draw a very small boundary, the software will think that you are
backtracking and erase the boundary.
When the cursor crosses over the line you are drawing, the drawn band is
complete and the color of the line will change to indicate that it is a boundary.
A band line will appear on the nearest lane.
If you keep drawing, each time the line crosses itself a new band will be
created, replacing the old band.
Note: You cannot perform Gaussian modeling on drawn bands, nor can you use
the Plot Band command.
The areas and quantities of drawn bands can be displayed in reports if you
select the Contour Area and Contour Qty formatting options. They can also
be displayed on the image using Band > Band Attributes and selecting
Contour Area and Contour Qty.
