Drawing Points

Waypoints may be added to a Survey Plain either by saving a Line as a set of points (as

opposed to the default of saving as a Profile) or with the Draw Points tool as discussed in
this next section.

To draw one or more points

1.

In the Survey planning setup dialog box (Figure 7 on page 16), click on the

Draw points

button (icon shown to the right).

2.

In an area of interest in your imagery, click to establish a point.

The system marks the location in your imagery with a small, red box. At the
same time, the system displays the Waypoint / Profile Editing dialog box (Figure 9),
revealing the point's coordinates in Northings and Eastings. The values may be edited
at this stage, with the changes registered through clicking on the

Apply

button.
