Manage Landmarks Panel

   

This option allows to add, delete, and move landmarks. The landmarks management panel (figure 2.20) displays the list of the current landmarks and provides the following tools:

• New: To create a new landmark. This button displays the sub-panel of figure 2.21 that allows to input the data for a new landmark: identifier and position. Once this data is input, pressing the button Ok adds the new landmark to the current set and closes the sub-panel. It is not possible to add a new landmark with the same identifier of an already existing landmark. The button Hide simply closes the panel.
• Move: This options opens the move landmark sub-panel (figure 2.22) in which a new position of the landmark can be input (the landmark identifier is shown but can not be modified). Again, pressing the button Ok enables the position modification and the button Hide closes the panel. The landmark to be moved is the one selected on the landmark list. A landmark can be selected with a single mouse click over its identifier.
• Delete: Deletes the currently selected landmark.
• Mark: Changes the color of the selected landmark from yellow (the default color) to red.
• Unmark: Changes the color of the selected landmark from red to yellow.

A double click over a landmark identifier opens a panel showing the information relative to the corresponding landmark (identifier and position). This panel is similar to the move landmark sub-panel of figure 2.22 (but in this case no data can be modified) and can be closed with the corresponding Hide button.
