Completing Intersection Passages for Sketch Map Creation

We propose a novel module for computing all possible passages through an intersection by assigning indexes to entry and exit points extracted from textual narratives and computing relative directions between them. Our method relies on a contiguity condition that ensures every input record is connected and computes relative directions using predefined tables. The resulting passages serve as the basis for constructing reliable sketch maps with topological accuracy. This approach facilitates early error detection in spatial data and supports future extensions to cases where intersections are incomplete by retaining non-contiguous records until additional data become available.
