Definition

Spatial network databases render support for spatial networks by providing the necessary data model, query language, storage structure, and indexing methods. Spatial networks can be modeled as graphs where nodes are points embedded in space. One characteristic that distinguishes a spatial network database is the primary focus on the role of connectivity in relationships rather than the spatial proximity between objects. These databases are the kernel of many important applications, including transportation planning; air traffic control; water, electric, and gas utilities; telephone networks; urban management; utility network maintenance, and irrigation canal management. The phenomena of interest for these applications are structured as a spatial graph, which consists of a finite collection of the points (i.e., nodes), the line-segments (i.e., edges) connecting the points, the location of the points and the attributes of the points and...
