Digitizing direction check

The comparison of the digitizing direction of a polygonal map object and the direction specified in the classifier for this type of objects is carried out.

If the classifier specifies a direction of «Counterclockwise (object at the left)», then the main contour must have a direction of «Counterclockwise», while subobjects should have a direction of «Clockwise».

If the direction is set to «Clockwise (object on the right)», then the main contour should have a direction of «Clockwise», and subobjects should have a direction of «Counterclockwise».

If the direction is set to «Arbitrary», then the main contour can have any direction. The digitizing direction of subobjects should be opposite to the digitizing direction of the main contour of the object.

During the control process in «Editing» mode, objects containing digitizing direction errors are corrected.
