Line of Sight (LOS)

Line of Sight - Rotate Observer

Once a single Line LOS is calculated, the user can use the Rotation toolbar to rotate the line of sight around the Observer. The step of rotation (in Degrees) can be adjusted on the Line of Sight Settings Dialog. There the user can also set  whether the previous LOS graphic will be deleted when a new one is drawn.

During rotation it is possible that the extent of the Line of Sight view will change and go outside of the extent of the window.  The Recalculate Extent button can be used to recalculate the extent of the current Line of Sight and zoom to it.

The example below shows the result of the rotation of the Observer full 360 degrees. The green areas are visible and the red ones are non-visible from the Observer
