3.4 General Directions for Object Mensuration

1. Activate Measurement Tool (choose Tools→Measure from the main

menu or the Measurement Tool icon, pictured on Table 4, ‘Group Four:

Image Management Icons,’ from the taskbar of icons).

2. The system displays a set of mensuration icons on the taskbar, and your

pointer changes to a canted arrow with tick marks (hash marks) under it.

3. Choose a mensuration method either by selecting one of the

mensuration icons or by right-clicking in your imagery to reveal a menu

of mensuration choices as shown in Figure 12. (The left-to-right lineup of

mensuration icons corresponds to the top-to-bottom choices in the

submenu.)

4. Draw your line by traversing the desired distance or area to be

measured, releasing your pointer, and finally left-clicking again to

complete the line.

Measure)

A line representing the type of mensuration technique you performed is drawn in

your imagery. Reading from left to right in the set of mensuration icons, the color

schemes for each type of mensuration line is as follows:

• Measure Distance: red

• Object Echo-Shadow: green

• Object Length: purple (magenta)

• Object Echo: green

• Object Shadow: cyan

At the same time that your measured line appears in the imagery, the

metrics for that line appear in a related field of TargetPro’s Cursor panel.

The different ways of mensurating with the Measurement Tool are explained

next.
