WebLine features can share endpoint vertices with other point features (node topology). Point features can be coincident with line features (point events). Two views: Features and topological elements. A layer of polygons can be described and used in the following ways: As collections of geographic features (points, lines, and polygons) As a graph ... WebMar 21, 2024 · A graph-based DCRNN structure is developed to extract and adaptively learn the relationships between bus lines in the network since bus passengers interchange between these lines. As the bus networks are not grid-like, we adopt graph convolution to learn the topological features of the network.
