WebMay 24, 2024 · Easy, slow, low memory footprint: compare each segment against all others and check for intersections.Complexity O(n 2).. Slightly faster, medium memory footprint (modified version of above): store edges in spatial "buckets", then perform above algorithm on per-bucket basis. Complexity O(n 2 / m) for m buckets (assuming uniform … WebIntersection ¶ Description ¶ This algorithm combines features from the Input layer and the Intersect Layer, resulting in features that cover both layers’ features. Input Feature (s) that only partially lie within the other layer’s feature (s) are split along the boundary of the other layer’s feature (s). hunter\u0027s moon 2020

However, for example in the case of road viaducts, the lines can cross without intersect, since they are at different levels. So, for these cases, the "Enable topological editing" option should be deselected.
