Select the line you want to edit.
To select a line, press the Select button (which then enters the active state) and draw a selection box on the screen by tapping and drag, so that it intersects the line you want to select.
If the frame intersects a line, then the Selection button enters the Edit mode. If no line is intersected, then the Selection button returns to its idle state. Once a line is set into edit mode, all of its points acquire a color code that indicates their position on the line: gray for the first, red for the last and cyan for all intermediate vertices. In the middle of each line segment, a small black cross is drawn.
You can modify the geometry of the line by clicking with the pointer any of the vertices and drag it to a new position.You can add new points to the editing line, by clicking with the pointer one of the black crosses and dragging it: a new point is created in its place (as well as two new crosses in the middles of two new defined line segments).
When pointing a vertex on the line by a long-press, a pop-up menu is displayed and you you can either delete the vertex or split the line into two parts in this very point (for the first or the last point of the line, only the delete command is available). Both lines that will result after the splitting action, will share the same name and symbol properties as the original one.
You can continue the line to any direction, by entering points with the pointer. At first, the points will be added next to the end vertex (red dot). If you want the new points to be added before the start vertex, click on the start vertex (gray dot), which will become red and the new vertices will be added ate the beggining of the line.
To finishing line editing, press again on the PENCIL icon. This opens the line’s Properties dialog and offers the
possibility of deleting, continuing, or accepting the changes (and changing the name and symbol of the line).
In the EXTREME version and inside the Greek mapping area, any change of the line geometry (move and add vertices) ask and receive elevation values from the Digital Elevation Model of the Toponavigator WMS.
