Direction of digitizing |
For classifier objects the user can appoint a direction of digitizing. The direction of a digitizing may be: - arbitrary; - predefined; - lower right ; - counter-clockwise (object at the left); - clockwise (object on the right).
For polygon objects the directions of digitizing can has following values: object at the left (detour of object counter-clockwise: it is used for reservoirs and deepenings of a relief) and object on the right (detour of object clockwise). For linear objects it is possible to use on the right above (for contours and elements of a relief), predefined (for those objects for which it have meaning to distinguish the beginning and the end of the metrics, for example, the rivers are digitized from a source to a mouth) and arbitrary for all other cases. Point objects have only an arbitrary direction of a digitizing. All others objects have arbitrary or predefined direction of a digitizing.
