Abstract:

Polybuiding from links of linear objects is practically applied in practice. Linear objects can be Lines, Polylines, Arcs, etc. In certain graphic softwares, the selection function is used when calculating area, coloring, creating boundary lines. However, before selecting, boundary objects must be processed to enclose closed areas to create closed areas. This article presents the technique for automatically finding and correcting regions for map editing. Errors in the area problem such as free end point, overlap, intersection are automatically detected and notified to the user.
