Once the view and location are selected, the next step is to create a polygon target scan area. This is done by finding the
location of interest and left clicking the cursor onto the spot of the map or satellite view. Each click creates an anchor
point, as shown below. Between each anchor point is a second point, an empty circle, that can be used for area adjustment.
To adjust the area, left click and drag any point to the desired position and release. The following figure shows the results
of polygon modification.
Figure 3-2. Polygon and Anchors.
When the target area polygon is modified the coordinates are not automatically displayed in the Coordinates box. Click
the Refresh Coordinates button to display the new coordinates in the Coordinates box below the map. The total area
encompassed by the polygon will be displayed in the Area box above the map. The modified target area polygon is shown
below. To clear the polygon and select new anchor points click on the Clear Polygon button at the top of the map.
