PST provides tools for editing both Road-Centre-line maps and Axial maps, so that they can be used in Network analysis. These tools are available under the ‘Create segment map’ option. Editing procedures include: Splitting polylines to line segments, Split lines in intersections/junctions and also Snapping, Merging and Removing tail lines, using user-defined settings. The ‘Remove tails’ and ‘Merge segments’ functions are especially designed to facilitate the conversion of Axial maps and Road-Centre-line maps respectively.
The ‘Create segment map’ tool also includes error-removing procedures, such as Removing duplicate lines and Removing lines of zero length.
